Flutter WebRTC Playing Audio

Question

I wish to play audio from remote stream of webrtc connection, in Flutter. The examples of flutter webrtc use RTCVideoRenderer, but there is no video in my case. The remote stream only consists of audio.

In short:

pc.onTrack = (event) {
  // how can I play the Audio stream in event.streams[0] ?
};

Code:

MediaStream _localStream = await createStream();
RTCPeerConnection pc = await createPeerConnection({});

_localStream.getTracks().forEach((track) async => await pc.addTrack(track, _localStream));  

pc.onTrack = (event) {
  // how can I play the Audio stream in event.streams[0] ?
};
    
Future<MediaStream> createStream() async {
  final Map<String, dynamic> mediaConstraints = {
    'audio': true,
    'video': false
  };

  MediaStream stream = await MediaDevices.getUserMedia(mediaConstraints);
  return stream;
}

How can I play the audio from remote stream in flutter?
