Android requirements

• Android minSdk 21 or later
• Android SDK Platform 36 installed

The plugin is compiled with Android API 36. If your application declares its own compileSdk, set it to 36 or later:

android {
    compileSdk = 36
}

Basic usage

Create one StringeeClient, subscribe to its event stream, and connect it with an access token generated by your server:

final client = StringeeClient();

final clientSubscription = client.eventStreamController.stream.listen((event) {
  switch (event['eventType']) {
    case StringeeClientEvents.didConnect:
      print('Connected as ${client.userId}');
      break;
    case StringeeClientEvents.requestAccessToken:
      // Fetch a new token from your server, then call client.connect(newToken).
      break;
    case StringeeClientEvents.incomingCall:
      final call = event['body'] as StringeeCall;
      // Present incoming-call UI and call call.initAnswer().
      break;
    case StringeeClientEvents.incomingCall2:
      final call = event['body'] as StringeeCall2;
      // Present incoming-call UI and call call.initAnswer().
      break;
  }
});

await client.connect(accessToken);

Create and observe an outgoing call:

final call = StringeeCall(client);

final callSubscription = call.eventStreamController.stream.listen((event) {
  if (event['eventType'] == StringeeCallEvents.didChangeSignalingState) {
    final state = event['body'] as StringeeSignalingState;
    print('Signaling state: $state');
  }
});

final result = await call.makeCallFromParams(
  MakeCallParams(
    fromUserId,
    toUserId,
    isVideoCall: true,
    videoQuality: VideoQuality.hd,
  ),
);

Release object-level subscriptions when they are no longer needed:

await callSubscription.cancel();
call.destroy();
await clientSubscription.cancel();
await client.disconnect();

StringeeCall2, StringeeChat, and StringeeVideoRoom expose their own event streams. Call their destroy() method after use so the plugin can close the corresponding stream subscription.
