代码片段到Handle Connected Participants

// Connect to a room.
var room = await TwilioProgrammableVideo.connect(connectOptions);

room.onConnected((Room room) {
  print('Connected to ${room.name}');
});

room.onConnectFailure((RoomConnectFailureEvent event) {
    print('Failed connecting, exception: ${event.exception.message}');
});

room.onDisconnected((RoomDisconnectEvent event) {
  print('Disconnected from ${event.room.name}');
});

room.onRecordingStarted((Room room) {
  print('Recording started in ${room.name}');
});

room.onRecordingStopped((Room room) {
  print('Recording stopped in ${room.name}');
});

// ... Assume we have received the connected callback.

// After receiving the connected callback the LocalParticipant becomes available.
var localParticipant = room.localParticipant;
print('LocalParticipant ${room.localParticipant.identity}');

// Get the first participant from the room.
var remoteParticipant = room.remoteParticipants[0];
print('RemoteParticipant ${remoteParticipant.identity} is in the room');
