# Local Participant

Manage local user media devices, control audio, video, and screenshare, and handle events in RealtimeKit meetings.

Prerequisites

Initialize the SDK and understand the meeting object structure. Refer to [Initialize SDK](https://developers.cloudflare.com/realtime/realtimekit/core/) and [Meeting Object Explained](https://developers.cloudflare.com/realtime/realtimekit/core/meeting-object-explained/).

## Introduction

The local user is accessible via `meeting.self` and contains all information and methods related to the current participant. This includes media controls, device management, participant metadata, and state information.

## Properties

### Metadata Properties

Access participant identifiers and display information:

JavaScript

```

// Participant identifiers

meeting.self.id; // Peer ID (unique per session)

meeting.self.userId; // User ID (persistent across sessions)

meeting.self.name; // Display name

meeting.self.picture; // Display picture URL


```

```

import { useRealtimeKitSelector } from "@cloudflare/realtimekit-react";


// Participant identifiers

const id = useRealtimeKitSelector((m) => m.self.id);

const userId = useRealtimeKitSelector((m) => m.self.userId);

const customParticipantId = useRealtimeKitSelector(

  (m) => m.self.customParticipantId,

);

const name = useRealtimeKitSelector((m) => m.self.name);

const picture = useRealtimeKitSelector((m) => m.self.picture);


```

### Change display name

Update the display name before joining the meeting:

JavaScript

```

await meeting.self.setName("New Name");


```

Note

Name changes only reflect across all participants if done before joining the meeting.

```

await meeting.self.setName("New Name");


```

Note

Name changes only reflect across all participants if done before joining the meeting.

Kotlin

```

meeting.localUser.setDisplayName("New Name")


```

Note

Name changes only reflect across all participants if done before joining the meeting.

Swift

```

meeting.localUser.setDisplayName(name: "New Name")


```

Note

Name changes only reflect across all participants if done before joining the meeting.

```

await meeting.self.setName("New Name");


```

Note

Name changes only reflect across all participants if done before joining the meeting.

Dart

```

if (meeting.permissions.miscellaneous.canEditDisplayName) {

  meeting.localUser.setDisplayName("New Name");

}


```

Note

Name changes only reflect across all participants if done before joining the meeting and the local user has preset permission to change the name.

            {device.label}

          </option>

        ))}

      </select>

    </div>

  );

}


```

```

Swift

```

// Get all audio devices

let audioDevices = meeting.localUser.getAudioDevices()


// Get all video devices

let videoDevices = meeting.localUser.getVideoDevices()


// Get currently selected audio device

let selectedAudioDevice = meeting.localUser.getSelectedAudioDevice()


// Get currently selected video device

let selectedVideoDevice = meeting.localUser.getSelectedVideoDevice()


```

```

import { useRealtimeKitClient } from "@cloudflare/realtimekit-react-native";

import { useState, useEffect } from "react";

import { FlatList, TouchableHighlight, Text, View } from "react-native";


function DeviceSelector() {

  const [meeting] = useRealtimeKitClient();

  const [audioDevices, setAudioDevices] = useState([]);

  const [videoDevices, setVideoDevices] = useState([]);


  useEffect(() => {

    if (!meeting) return;


    const loadDevices = async () => {

      const audio = await meeting.self.getAudioDevices();

      const video = await meeting.self.getVideoDevices();

      setAudioDevices(audio);

      setVideoDevices(video);

    };


    loadDevices();

  }, [meeting]);


  const handleDeviceChange = async (device) => {

    await meeting.self.setDevice(device);

  };


  return (

    <View>

      <FlatList

        data={audioDevices}

        renderItem={({ item }) => (

          <TouchableHighlight onPress={() => handleDeviceChange(item)}>

            <Text>{item.label}</Text>

          </TouchableHighlight>

        )}

        keyExtractor={(item) => item.deviceId}

      />

    </View>

  );

}


```

Get current devices being used:

```

const currentDevices = meeting.self.getCurrentDevices();

// Returns: { audio: MediaDeviceInfo, video: MediaDeviceInfo, speaker: MediaDeviceInfo }


```

Dart

```

// Get all audio devices

final audioDevices = await meeting.localUser.getAudioDevices();


// Get all video devices

final videoDevices = await meeting.localUser.getVideoDevices();


// Get currently selected audio device

final selectedAudioDevice = meeting.localUser.getSelectedAudioDevice();


// Get currently selected video device

final selectedVideoDevice = meeting.localUser.getSelectedVideoDevice();


```

### Change device

Switch to a different media device:

JavaScript

```

// Get all devices

const devices = await meeting.self.getAllDevices();


// Set a specific device (replaces device of the same kind)

await meeting.self.setDevice(devices[0]);


```

Use the device selector example from the previous section. The `handleDeviceChange` function demonstrates how to switch devices.

Kotlin

```

// Get all audio devices

val audioDevices = meeting.localUser.getAudioDevices()


// Set audio device

meeting.localUser.setAudioDevice(audioDevices[0])


// Get all video devices

val videoDevices = meeting.localUser.getVideoDevices()


// Set video device

meeting.localUser.setVideoDevice(videoDevices[0])


// Switch between front and back camera on devices with 2 cameras

meeting.localUser.switchCamera()


```

Swift

```

// Set audio device

meeting.localUser.setAudioDevice(device)


// Set video device

meeting.localUser.setVideoDevice(videoDevice: device)


// Switch between front and back camera

meeting.localUser.switchCamera()


```

Use the device selector example from the previous section. The `handleDeviceChange` function demonstrates how to switch devices.

JavaScript

```

const handleDeviceChange = async (device) => {

  await meeting.self.setDevice(device);

};


```

Dart

```

// Get all available audio devices

final audioDevices = await meeting.localUser.getAudioDevices();


// Switch audio device

await meeting.localUser.setAudioDevice(audioDevices[1]);


// Get all available video devices

final videoDevices = await meeting.localUser.getVideoDevices();


// Switch video device

await meeting.localUser.setVideoDevice(videoDevices[1]);


// Switch between available camera sources

meeting.localUser.switchCamera();


```

## Display local video

### Register video element

Attach the local video track to a `<video>` element:

```

<video id="local-video" autoplay playsinline></video>


```

JavaScript

```

const videoElement = document.getElementById("local-video");


// Register the video element to display video

meeting.self.registerVideoElement(videoElement);


// For local preview (not sent to other users), pass true as second argument

meeting.self.registerVideoElement(videoElement, true);


```

### Deregister video element

Remove the video element when no longer needed:

JavaScript

```

meeting.self.deregisterVideoElement(videoElement);


```

### Use UI Kit component

Display local video with the UI Kit video tile component:

```

import { RtkParticipantTile } from "@cloudflare/realtimekit-react-ui";

import { useRealtimeKitSelector } from "@cloudflare/realtimekit-react";


function LocalVideo() {

  const localUser = useRealtimeKitSelector((m) => m.self);


  return <RtkParticipantTile participant={localUser} />;

}


```

### Manage video element manually

Create custom video element implementations:

```

import {

  useRealtimeKitClient,

  useRealtimeKitSelector,

} from "@cloudflare/realtimekit-react";

import { useEffect, useRef } from "react";


function LocalVideoCustom() {

  const [meeting] = useRealtimeKitClient();

  const videoEnabled = useRealtimeKitSelector((m) => m.self.videoEnabled);

  const videoTrack = useRealtimeKitSelector((m) => m.self.videoTrack);

  const videoRef = useRef(null);


  useEffect(() => {

    if (!videoRef.current || !meeting) return;


    // Register video element

    meeting.self.registerVideoElement(videoRef.current);


    return () => {

      // Cleanup: deregister on unmount

      meeting.self.deregisterVideoElement(videoRef.current);

    };

  }, [meeting]);


  return (

    <video

      ref={videoRef}

      autoPlay

      playsInline

      muted

      style={{ display: videoEnabled ? "block" : "none" }}

    />

  );

}


```

### Get video view

Retrieve a self-preview video view that renders the local camera stream:

Kotlin

```

// Get the self-preview video view

val videoView = meeting.localUser.getSelfPreview()


```

For rendering other participants' video, use:

Kotlin

```

// Get video view for camera stream

val participantVideoView = participant.getVideoView()


// Get video view for screenshare stream

val screenshareView = participant.getScreenShareVideoView()


```

### Manage lifecycle

Control video rendering with lifecycle methods:

Kotlin

```

// Start rendering video

videoView.renderVideo()


// Stop rendering video (but keep the view)

videoView.stopVideoRender()


// Release native resources when done

videoView.release()


```

### Complete Example

Kotlin

```

import android.os.Bundle

import android.widget.FrameLayout

import androidx.appcompat.app.AppCompatActivity

import io.dyte.core.VideoView


class MainActivity : AppCompatActivity() {

    private lateinit var videoView: VideoView


    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)


        // Get the self-preview video view

        videoView = meeting.localUser.getSelfPreview()


        // Add to your layout

        val container = findViewById<FrameLayout>(R.id.video_container)

        container.addView(videoView)


        // Start rendering

        videoView.renderVideo()

    }


    override fun onPause() {

        super.onPause()

        // Stop rendering when activity is paused

        videoView.stopVideoRender()

    }


    override fun onResume() {

        super.onResume()

        // Resume rendering when activity is resumed

        videoView.renderVideo()

    }


    override fun onDestroy() {

        super.onDestroy()

        // Clean up resources

        videoView.release()

    }

}


```

### Get video view

Retrieve video views that render the participant's video streams:

Swift

```

// Get video view for local camera stream

let videoView = meeting.localUser.getVideoView()


// Get video view for screenshare stream

let screenshareView = meeting.localUser.getScreenShareVideoView()


```

### Manage lifecycle

The `UIView` handles its own lifecycle automatically and cleans up native resources when it exits the current window. No manual cleanup is required.

### Example

Swift

```

import UIKit

import RealtimeKit


class VideoViewController: UIViewController {

    private var videoView: UIView?


    override func viewDidLoad() {

        super.viewDidLoad()


        // Get the video view for local camera

        videoView = meeting.localUser.getVideoView()


        // Add to your view hierarchy

        if let videoView = videoView {

            videoView.frame = view.bounds

            videoView.autoresizingMask = [.flexibleWidth, .flexibleHeight]

            view.addSubview(videoView)

        }

    }

}


```

For screenshare:

Swift

```

// Get and display screenshare view

let screenshareView = meeting.localUser.getScreenShareVideoView()

if let screenshareView = screenshareView {

    screenshareView.frame = view.bounds

    screenshareView.autoresizingMask = [.flexibleWidth, .flexibleHeight]

    view.addSubview(screenshareView)

}


```

```

import React from "react";

import { useRealtimeKitSelector } from "@cloudflare/realtimekit-react-native";

import { MediaStream, RTCView } from "@cloudflare/react-native-webrtc";


export default function VideoView() {

  const { videoTrack } = useRealtimeKitSelector(

    (m) => m.participants.active,

  ).toArray()[0];

  const stream = new MediaStream(undefined);

  stream.addTrack(videoTrack);

  return (

    <RTCView

      objectFit={"cover"}

      style={{ flex: 1 }}

      streamURL={stream.toURL()}

      mirror={true}

      zOrder={1}

    />

  );

}


```

### VideoView widget

Display video streams with the `VideoView` widget:

Dart

```

import 'package:realtimekit_core/realtimekit_core.dart';

import 'package:flutter/material.dart';


class LocalVideoView extends StatelessWidget {

  final RtkMeetingParticipant localUser;


  const LocalVideoView({Key? key, required this.localUser}) : super(key: key);


  @override

  Widget build(BuildContext context) {

    return VideoView(

      meetingParticipant: localUser,

      isSelfParticipant: true,

    );

  }

}


```

### VideoView parameters

The `VideoView` widget accepts the following parameters:

* `meetingParticipant` (required): The `RtkMeetingParticipant` whose video should be displayed
* `isSelfParticipant` (optional): Set to `true` for the local participant's self-preview, defaults to `false`
* `key` (optional): Widget key for Flutter's widget tree management

### Example

Dart

```

import 'package:flutter/material.dart';

import 'package:realtimekit_core/realtimekit_core.dart';


class MeetingScreen extends StatelessWidget {

  final RtkMeeting meeting;


  const MeetingScreen({Key? key, required this.meeting}) : super(key: key);


  @override

  Widget build(BuildContext context) {

    return Scaffold(

      appBar: AppBar(title: Text('Video Preview')),

      body: Container(

        child: VideoView(

          meetingParticipant: meeting.localUser,

          isSelfParticipant: true,

        ),

      ),

    );

  }

}


```

For displaying other participants' video:

Dart

```

// Display remote participant video

VideoView(

  meetingParticipant: remoteParticipant,

  isSelfParticipant: false,

)


```

The `VideoView` widget automatically handles video rendering and resource cleanup based on Flutter's widget lifecycle.

## Events

### Room joined

Fires when the local user joins the meeting:

JavaScript

```

meeting.self.on("roomJoined", () => {

  console.log("Successfully joined the meeting");

});


```

```

const roomJoined = useRealtimeKitSelector((m) => m.self.roomJoined);


useEffect(() => {

  if (roomJoined) {

    console.log("Successfully joined the meeting");

  }

}, [roomJoined]);


```

Or use event listener:

```

useEffect(() => {

  if (!meeting) return;


  const handleRoomJoined = () => {

    console.log("Successfully joined the meeting");

  };


  meeting.self.on("roomJoined", handleRoomJoined);


  return () => {

    meeting.self.off("roomJoined", handleRoomJoined);

  };

}, [meeting]);


```

Android SDK uses a different event model. Monitor `roomJoined` property changes or use listeners for state changes.

iOS SDK uses a different event model. Monitor `roomJoined` property changes or use listeners for state changes.

```

const roomJoined = useRealtimeKitSelector((m) => m.self.roomJoined);


useEffect(() => {

  if (roomJoined) {

    console.log("Successfully joined the meeting");

  }

}, [roomJoined]);


```

Or use event listener:

```

useEffect(() => {

  if (!meeting) return;


  const handleRoomJoined = () => {

    console.log("Successfully joined the meeting");

  };


  meeting.self.on("roomJoined", handleRoomJoined);


  return () => {

    meeting.self.off("roomJoined", handleRoomJoined);

  };

}, [meeting]);


```

Flutter SDK uses a different event model. Monitor `roomJoined` property changes or use listeners for state changes.

### Room left

Fires when the local user leaves the meeting:

JavaScript

```

meeting.self.on("roomLeft", ({ state }) => {

  console.log("Left the meeting with state:", state);


  // Handle different leave states

  if (state === "left") {

    console.log("User voluntarily left");

  } else if (state === "kicked") {

    console.log("User was kicked from the meeting");

  } else if (state === "ended") {

    console.log("Meeting has ended");

  } else if (state === "disconnected") {

    console.log("Lost connection to meeting");

  }

});


```

**Possible state values:** `'left'`, `'kicked'`, `'ended'`, `'rejected'`, `'disconnected'`, `'failed'`

```

const roomJoined = useRealtimeKitSelector((m) => m.self.roomJoined);


useEffect(() => {

  if (!roomJoined) {

    console.log("Left the meeting");

  }

}, [roomJoined]);


```

Or use event listener for detailed state:

```

meeting.self.on("roomLeft", ({ state }) => {

  if (state === "left") {

    console.log("User voluntarily left");

  } else if (state === "kicked") {

    console.log("User was kicked");

  }

});


```

Use `RtkSelfEventListener` to monitor when the local user is removed from the meeting:

Kotlin

```

meeting.addSelfEventListener(object : RtkSelfEventListener {

    override fun onRemovedFromMeeting() {

        // display alert that user is no longer in the meeting

    }

})


```

iOS SDK uses a different event model. Monitor `roomJoined` property changes or use listeners for state changes.

```

const roomJoined = useRealtimeKitSelector((m) => m.self.roomJoined);


useEffect(() => {

  if (!roomJoined) {

    console.log("Left the meeting");

  }

}, [roomJoined]);


```

Or use event listener for detailed state:

```

meeting.self.on("roomLeft", ({ state }) => {

  if (state === "left") {

    console.log("User voluntarily left");

  } else if (state === "kicked") {

    console.log("User was kicked");

  }

});


```

Dart

```

class MeetingSelfListener extends RtkSelfEventListener {

  @override

  void onRemovedFromMeeting() {

    // User was removed from the meeting (kicked or meeting ended)

    // Display alert or navigate to exit screen

  }

}


// Add the listener

meeting.addSelfEventListener(MeetingSelfListener());


```

### Video update

Fires when video is enabled or disabled:

JavaScript

```

meeting.self.on("videoUpdate", ({ videoEnabled, videoTrack }) => {

  console.log("Video state:", videoEnabled);


  if (videoEnabled) {

    // Video track is available, can display it

    const videoElement = document.getElementById("my-video");

    const stream = new MediaStream();

    stream.addTrack(videoTrack);

    videoElement.srcObject = stream;

    videoElement.play();

  }

});


```

```

const videoEnabled = useRealtimeKitSelector((m) => m.self.videoEnabled);

const videoTrack = useRealtimeKitSelector((m) => m.self.videoTrack);


useEffect(() => {

  if (videoEnabled && videoTrack) {

    console.log("Video is enabled");

    // Handle video track

  }

}, [videoEnabled, videoTrack]);


```

Kotlin

```

meeting.addSelfEventListener(object : RtkSelfEventListener {

    override fun onVideoUpdate(isEnabled: Boolean) {

        if (isEnabled) {

            // video is enabled, other participants can see local user

        } else {

            // video is disabled, other participants cannot see local user

        }

    }

})


```

Swift

```

extension MeetingViewModel: RtkSelfEventListener {

    func onVideoUpdate(isEnabled: Bool) {

        if (isEnabled) {

            // video is enabled, other participants can see local user

        } else {

            // video is disabled, other participants cannot see local user

        }

    }

}


```

```

const videoEnabled = useRealtimeKitSelector((m) => m.self.videoEnabled);

const videoTrack = useRealtimeKitSelector((m) => m.self.videoTrack);


useEffect(() => {

  if (videoEnabled && videoTrack) {

    console.log("Video is enabled");

    // Handle video track

  }

}, [videoEnabled, videoTrack]);


```

Flutter SDK uses a different event model. Monitor `videoEnabled` property changes.

### Audio update

Fires when audio is enabled or disabled:

JavaScript

```

meeting.self.on("audioUpdate", ({ audioEnabled, audioTrack }) => {

  console.log("Audio state:", audioEnabled);


  if (audioEnabled) {

    // Audio track is available

    console.log("Microphone is on");

  }

});


```

```

const audioEnabled = useRealtimeKitSelector((m) => m.self.audioEnabled);

const audioTrack = useRealtimeKitSelector((m) => m.self.audioTrack);


useEffect(() => {

  if (audioEnabled && audioTrack) {

    console.log("Audio is enabled");

    // Handle audio track

  }

}, [audioEnabled, audioTrack]);


```

Kotlin

```

meeting.addSelfEventListener(object : RtkSelfEventListener {

    override fun onAudioUpdate(isEnabled: Boolean) {

        if (isEnabled) {

            // audio is enabled, other participants can hear local user

        } else {

            // audio is disabled, other participants cannot hear local user

        }

    }

})


```

Swift

```

extension MeetingViewModel: RtkSelfEventListener {

    func onAudioUpdate(isEnabled: Bool) {

        if (isEnabled) {

            // audio is enabled, other participants can hear local user

        } else {

            // audio is disabled, other participants cannot hear local user

        }

    }

}


```

```

const audioEnabled = useRealtimeKitSelector((m) => m.self.audioEnabled);

const audioTrack = useRealtimeKitSelector((m) => m.self.audioTrack);


useEffect(() => {

  if (audioEnabled && audioTrack) {

    console.log("Audio is enabled");

    // Handle audio track

  }

}, [audioEnabled, audioTrack]);


```

Flutter SDK uses a different event model. Monitor `audioEnabled` property changes.

### Screen share update

Fires when screen sharing starts or stops:

JavaScript

```

meeting.self.on(

  "screenShareUpdate",

  ({ screenShareEnabled, screenShareTracks }) => {

    console.log("Screen share state:", screenShareEnabled);


    if (screenShareEnabled) {

      // Screen share tracks are available

      const screenElement = document.getElementById("my-screen-share");

      const stream = new MediaStream();

      stream.addTrack(screenShareTracks.video);

      if (screenShareTracks.audio) {

        stream.addTrack(screenShareTracks.audio);

      }

      screenElement.srcObject = stream;

      screenElement.play();

    }

  },

);


```

```

const screenShareEnabled = useRealtimeKitSelector(

  (m) => m.self.screenShareEnabled,

);

const screenShareTracks = useRealtimeKitSelector(

  (m) => m.self.screenShareTracks,

);


useEffect(() => {

  if (screenShareEnabled && screenShareTracks) {

    console.log("Screen sharing is active");

    // Handle screen share tracks

  }

}, [screenShareEnabled, screenShareTracks]);


```

Kotlin

```

meeting.addSelfEventListener(object : RtkSelfEventListener {

    override fun onScreenShareStartFailed(reason: String) {

        // screen share failed to start

    }


    override fun onScreenShareUpdate(isEnabled: Boolean) {

        if (isEnabled) {

            // screen share is enabled

        } else {

            // screen share is disabled

        }

    }

})


```

Swift

```

meeting.addSelfEventListener(self)


extension MeetingViewModel: RtkSelfEventListener {

    func onRemovedFromMeeting() {

        // User was removed from the meeting (kicked or meeting ended)

        // Display alert or navigate to exit screen

    }


    func onMeetingRoomDisconnected() {

        // Lost connection to the meeting room

        // Display reconnection UI or error message

    }

}


```

You can also monitor the `roomJoined` property for state changes:

Swift

```

let isInMeeting = meeting.localUser.roomJoined


```

```

const screenShareEnabled = useRealtimeKitSelector(

  (m) => m.self.screenShareEnabled,

);

const screenShareTracks = useRealtimeKitSelector(

  (m) => m.self.screenShareTracks,

);


useEffect(() => {

  if (screenShareEnabled && screenShareTracks) {

    console.log("Screen sharing is active");

    // Handle screen share tracks

  }

}, [screenShareEnabled, screenShareTracks]);


```

Flutter SDK uses a different event model. Monitor `screenShareEnabled` property changes.

### Device update

Fires when the active device changes:

JavaScript

```

meeting.self.on("deviceUpdate", ({ device }) => {

  // Handle device change

  if (device.kind === "audioinput") {

    console.log("Microphone changed:", device.label);

  } else if (device.kind === "videoinput") {

    console.log("Camera changed:", device.label);

  } else if (device.kind === "audiooutput") {

    console.log("Speaker changed:", device.label);

  }

});


```

```

useEffect(() => {

  if (!meeting) return;


  const handleDeviceUpdate = ({ device }) => {

    if (device.kind === "audioinput") {

      console.log("Microphone changed:", device.label);

    } else if (device.kind === "videoinput") {

      console.log("Camera changed:", device.label);

    }

  };


  meeting.self.on("deviceUpdate", handleDeviceUpdate);


  return () => {

    meeting.self.off("deviceUpdate", handleDeviceUpdate);

  };

}, [meeting]);


```

Kotlin

```

meeting.self.addSelfEventListener(object : RtkSelfEventListener() {

    override fun onAudioDeviceChanged(device: AudioDevice) {

        // Handle audio device change

        println("Audio device changed: ${device.label}")

    }


    override fun onVideoDeviceChanged(device: VideoDevice) {

        // Handle video device change

        println("Video device changed: ${device.label}")

    }

})


```

Swift

```

meeting.self.addSelfEventListener(self)


// RtkSelfEventListener implementation

func onAudioDeviceChanged(device: AudioDevice) {

    // Handle audio device change

    print("Audio device changed: \(device.label)")

}


func onVideoDeviceChanged(device: VideoDevice) {

    // Handle video device change

    print("Video device changed: \(device.label)")

}


```

```

useEffect(() => {

  if (!meeting) return;


  const handleDeviceUpdate = ({ device }) => {

    if (device.kind === "audioinput") {

      console.log("Microphone changed:", device.label);

    } else if (device.kind === "videoinput") {

      console.log("Camera changed:", device.label);

    }

  };


  meeting.self.on("deviceUpdate", handleDeviceUpdate);


  return () => {

    meeting.self.off("deviceUpdate", handleDeviceUpdate);

  };

}, [meeting]);


```

Dart

```

class DeviceChangeListener extends RtkSelfEventListener {

  @override

  void onAudioDeviceChanged(AudioDevice audioDevice) {

    // Handle audio device change

    print('Audio device changed: ${audioDevice.label}');

  }


  @override

  void onVideoDeviceChanged(VideoDevice videoDevice) {

    // Handle video device change

    print('Video device changed: ${videoDevice.label}');

  }

}


// Add the listener

meeting.addSelfEventListener(DeviceChangeListener());


```

### Device List Update

Triggered when the list of available devices changes (device plugged in or out):

JavaScript

```

meeting.self.on("deviceListUpdate", ({ added, removed, devices }) => {

  console.log("Device list updated");

  console.log("Added devices:", added);

  console.log("Removed devices:", removed);

  console.log("All devices:", devices);

});


```

```

useEffect(() => {

  if (!meeting) return;


  const handleDeviceListUpdate = ({ added, removed, devices }) => {

    console.log("Device list updated");

    console.log("Added devices:", added);

    console.log("Removed devices:", removed);

    console.log("All devices:", devices);

  };


  meeting.self.on("deviceListUpdate", handleDeviceListUpdate);


  return () => {

    meeting.self.off("deviceListUpdate", handleDeviceListUpdate);

  };

}, [meeting]);


```

Kotlin

```

meeting.addSelfEventListener(object : RtkSelfEventListener {

    // Triggered when audio devices are added or removed

    override fun onAudioDevicesUpdated() {

        val audioDevices = meeting.localUser.getAudioDevices()

        // Update UI with new audio device list

    }

})


```

Swift

```

meeting.addSelfEventListener(object: RtkSelfEventListener {

    // Triggered when audio devices are added or removed

    func onAudioDevicesUpdated() {

        let audioDevices = meeting.localUser.getAudioDevices()

        // Update UI with new audio device list

    }

})


```

```

useEffect(() => {

  if (!meeting) return;


  const handleDeviceListUpdate = ({ added, removed, devices }) => {

    console.log("Device list updated");

    console.log("Added devices:", added);

    console.log("Removed devices:", removed);

    console.log("All devices:", devices);

  };


  meeting.self.on("deviceListUpdate", handleDeviceListUpdate);


  return () => {

    meeting.self.off("deviceListUpdate", handleDeviceListUpdate);

  };

}, [meeting]);


```

Dart

```

class DeviceListListener extends RtkSelfEventListener {

  final RealtimekitClient meeting;


  DeviceListListener(this.meeting);


  @override

  void onAudioDevicesUpdated(List<AudioDevice> devices) {

    // Triggered when audio devices are added or removed

    // Update UI with new audio device list

  }


  @override

  void onVideoDeviceChanged(VideoDevice videoDevice) {

    // Handle video device change

    print('Video device changed to: ${videoDevice.label}');

  }

}


// Add the listener

meeting.addSelfEventListener(DeviceListListener(meeting));


```

### Network Quality Score

Monitor your own network quality:

JavaScript

```

meeting.self.on(

  "mediaScoreUpdate",

  ({ kind, isScreenshare, score, scoreStats }) => {

    if (kind === "video") {

      console.log(

        `Your ${isScreenshare ? "screenshare" : "video"} quality score is`,

        score,

      );

    }


    if (kind === "audio") {

      console.log("Your audio quality score is", score);

    }


    if (score < 5) {

      console.log("Your media quality is poor");

    }

  },

);


```

The `scoreStats` object provides detailed statistics:

JavaScript

```

// Audio Producer

{

  "kind": "audio",

  "isScreenshare": false,

### Permission Updates

Triggered when permissions are updated dynamically:

JavaScript

```

// Listen to specific permission updates

meeting.self.permissions.on("chatUpdate", () => {

  console.log("Chat permissions updated");

  // Check meeting.self.permissions for updated permissions

});


meeting.self.permissions.on("pollsUpdate", () => {

  console.log("Polls permissions updated");

});


meeting.self.permissions.on("pluginsUpdate", () => {

  console.log("Plugins permissions updated");

});


// Listen to all permission updates

meeting.self.permissions.on("*", () => {

  console.log("Permissions updated");

});


```

Monitor permissions using selectors:

```

const permissions = useRealtimeKitSelector((m) => m.self.permissions);


useEffect(() => {

  console.log("Permissions updated:", permissions);

}, [permissions]);


```

Android SDK uses a different permissions model. Refer to the Android-specific documentation.

iOS SDK uses a different permissions model. Refer to the iOS-specific documentation.

Monitor permissions using selectors:

```

const permissions = useRealtimeKitSelector((m) => m.self.permissions);


useEffect(() => {

  console.log("Permissions updated:", permissions);

}, [permissions]);


```

Flutter SDK uses a different permissions model. Refer to the Flutter-specific documentation.

### Media Permission Errors

Triggered when media permissions are denied or media capture fails:

JavaScript

```

meeting.self.on("mediaPermissionError", ({ message, kind }) => {

  console.log(`Failed to capture ${kind}: ${message}`);


  // Handle different error types

  if (message === "DENIED") {

    console.log("User denied permission");

  } else if (message === "SYSTEM_DENIED") {

    console.log("System denied permission");

  } else if (message === "COULD_NOT_START") {

    console.log("Failed to start media stream");

  }

});


```

**Possible values:**

* `message`: `'DENIED'`, `'SYSTEM_DENIED'`, `'COULD_NOT_START'`
* `kind`: `'audio'`, `'video'`, `'screenshare'`

```

useEffect(() => {

  if (!meeting) return;


  const handlePermissionError = ({ message, kind }) => {

    console.log(`Failed to capture ${kind}: ${message}`);


    if (message === "DENIED") {

      // Show UI to guide user to grant permissions

    }

  };


  meeting.self.on("mediaPermissionError", handlePermissionError);


  return () => {

    meeting.self.off("mediaPermissionError", handlePermissionError);

  };

}, [meeting]);


```

Kotlin

```

meeting.addSelfEventListener(object : RtkSelfEventListener {

    override fun onMeetingRoomJoinedWithoutCameraPermission() {

        // meeting joined without camera permission

    }


    override fun onMeetingRoomJoinedWithoutMicPermission() {

        // meeting joined without microphone permission

    }

})


```

Swift

```

meeting.addSelfEventListener(self)


extension MeetingViewModel: RtkSelfEventListener {

    func onMeetingRoomJoinedWithoutCameraPermission() {

        // meeting joined without camera permission

    }


    func onMeetingRoomJoinedWithoutMicPermission() {

        // meeting joined without microphone permission

    }

}


```

You can also check permission status using properties:

Swift

```

let hasCameraPermission = meeting.localUser.isCameraPermissionGranted

let hasMicPermission = meeting.localUser.isMicrophonePermissionGranted


```

```

useEffect(() => {

  if (!meeting) return;


  const handlePermissionError = ({ message, kind }) => {

    console.log(`Failed to capture ${kind}: ${message}`);


    if (message === "DENIED") {

      // Show UI to guide user to grant permissions

    }

  };


  meeting.self.on("mediaPermissionError", handlePermissionError);


  return () => {

    meeting.self.off("mediaPermissionError", handlePermissionError);

  };

}, [meeting]);


```

Dart

```

class PermissionListener extends RtkSelfEventListener {

  @override

  void onMeetingRoomJoinedWithoutCameraPermission() {

    // Meeting joined without camera permission

  }


  @override

  void onMeetingRoomJoinedWithoutMicPermission() {

    // Meeting joined without microphone permission

  }

}


// Add the listener

meeting.addSelfEventListener(PermissionListener());


```

You can also check permission status using properties:

Dart

```

final hasCameraPermission = meeting.localUser.isCameraPermissionGranted;

final hasMicPermission = meeting.localUser.isMicrophonePermissionGranted;


```

### Waitlist Status

For meetings with waiting room enabled:

Monitor the `roomState` property for waitlist status. The value `'waitlisted'` indicates the user is in the waiting room.

```

const roomState = useRealtimeKitSelector((m) => m.self.roomState);


useEffect(() => {

  if (roomState === "waitlisted") {

    console.log("Waiting for host to admit you");

  }

}, [roomState]);


```

Kotlin

```

// Get current waitlist status

val waitListStatus = meeting.localUser.waitListStatus


// Listen to waitlist status changes

meeting.addSelfEventListener(object : RtkSelfEventListener {

    override fun onWaitListStatusUpdate(waitListStatus: WaitListStatus) {

        // handle waitlist status here

    }

})


```

Swift

```

// Get current waitlist status

let waitListStatus = meeting.localUser.waitListStatus


// Listen to waitlist status changes

extension MeetingViewModel: RtkSelfEventListener {

    func onWaitlistedUpdate() {

        // handle waitlist update

    }

}


```

```

const roomState = useRealtimeKitSelector((m) => m.self.roomState);


useEffect(() => {

  if (roomState === "waitlisted") {

    console.log("Waiting for host to admit you");

  }

}, [roomState]);


```

Flutter SDK uses a different event model. Monitor `stageStatus` or relevant properties for waitlist status.

### iOS-Specific Events

The iOS SDK provides additional platform-specific events:

#### Proximity Sensor

Triggered when the proximity sensor detects a change (useful for earpiece detection):

Swift

```

extension MeetingViewModel: RtkSelfEventListener {

    func onProximityChanged() {

        // Handle proximity sensor change

        // Useful for detecting when device is near user's ear

    }

}


```

#### Webinar Events

For webinar-specific functionality:

Swift

```

extension MeetingViewModel: RtkSelfEventListener {

    func onWebinarPresentRequestReceived() {

        // Handle request to present in webinar

    }


    func onStoppedPresenting() {

        // Handle stopped presenting in webinar

    }

}


```

#### Room Messages

Listen to broadcast messages in the room:

Swift

```

extension MeetingViewModel: RtkSelfEventListener {

    func onRoomMessage() {

        // Handle room broadcast message

    }

}


```

## Pin and Unpin

Pin or unpin yourself in the meeting (requires appropriate permissions):

Web SDK does not currently support pinning the local participant.

Web SDK does not currently support pinning the local participant.

Android SDK does not currently support pinning the local participant.

Swift

```

// Pin yourself

meeting.localUser.pin()


// Unpin yourself

meeting.localUser.unpin()


// Check if pinned

let isPinned = meeting.localUser.isPinned


```

```

// Pin yourself

await meeting.self.pin();


// Unpin yourself

await meeting.self.unpin();


// Check if pinned

const isPinned = meeting.self.isPinned;


```

Flutter SDK does not currently support pinning the local participant.

## Update Media Constraints

Update video or screenshare resolution at runtime:

Web SDK does not currently expose runtime constraint updates for local participant.

Web SDK does not currently expose runtime constraint updates for local participant.

```

meeting.self.updateVideoConstraints({

  width: { ideal: 1920 },

  height: { ideal: 1080 },

});


```

### Update Screenshare Constraints

Update screenshare resolution while already streaming:

```

meeting.self.updateScreenshareConstraints({

  width: { ideal: 1920 },
