Permissions and entitlements

You'll need to request camera and/or microphone permissions (depending on your use case). This must be done within your platform-specific code:

Permissions are configured in AppManifest.xml. In addition to camera and microphone, you may need to add networking and bluetooth permissions.

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />

Connect to LiveKit

Add the following code to connect and publish audio/video to a room:

final roomOptions = RoomOptions(
  adaptiveStream: true,
  dynacast: true,
  // ... your room options
)

final room = Room();

await room.connect(url, token, roomOptions: roomOptions);
try {
  // video will fail when running in ios simulator
  await room.localParticipant.setCameraEnabled(true);
} catch (error) {
  print('Could not publish video, error: $error');
}

await room.localParticipant.setMicrophoneEnabled(true);
