2. Import omnitalk_sdk in your app

Add following lines to pubspec.yaml under dependencies

    dependencies:
        omnitalk_sdk: 0.0.1
        flutter_webrtc ^0.9.24

or you can add it by runnning code below in terminal

    flutter pub add omnitalk_sdk

3. Initialize Omnitalk instance with your service id and key

final Omnitalk omnitalk;
omnitalk = Omnitalk(service id, service key)

4. Get you RTCVideoRenderer

Omnitalk supports 32 users at the same time.
Declare renderers and pass it publish() or subscribe() for its use.

Usage

In order to make a real-time video conference (omnitalk will expand it to video call, audio call, audio conference and others any time soon), you might need these methods below.

1) create session

Argument 'user_id' is optional. If you don't put user_id, omnitalk will give you a random id.

session = await omnitalk.createSession(user_id);

2) create room & join the room

Make a room and join the room. You can get a room list first before make a room. You can also pass a room subject, room secret if you want.

roomObj = await omnitalk.createRoom(subject: roomSubject);
roomId = roomObj?["room_id"];
await omnitalk.joinRoom(room_id: roomId);

3) publish

By publishing you start broadcasting. Pass the RTCVideoRenderer localrenderer and add it in your UI widget.

publishIdx = await omnitalk.publish(
        callType: "videocall", record: false, localRenderer: localVideo);

4) subscribe

To subscribe other broadcasting, pass the publish index. You can get publish_index by listening 'BROADCASTING_EVENT' from server. OryYou can get participants list before you subscribe.

 var partiResult = await omnitalk.partiList(roomId);

    for (var parti in partiResult) {
      int pubIdx = parti["publish_idx"];
      partiList.add(pubIdx);
    }

    for (int i = 0; i < partiList.length; i++) {
      int pubidx = partiList[i];

      await omnitalk.subscribe(
          publishIdx: pubidx, remoteRenderer: remoteVideos[i]);
