如何在Flutter中集成Twilio JavaScript视频库

Question

我是Flutter的新手，我想在我的Flutter应用程序中集成Twilio JavaScript视频库。我不确定这是否有可能。求你了，我需要一些指导。

Answer 1

您可以使用包https://pub.dev/packages/twilio_programmable_video
示例https://gitlab.com/twilio-flutter/programmable-video/-/tree/master/programmable_video/example

Join a room的代码段

Room _room;
final Completer<Room> _completer = Completer<Room>();
void _onConnected(Room room) {
print('Connected to ${room.name}');
_completer.complete(_room);
}
void _onConnectFailure(RoomConnectFailureEvent event) {
print('Failed to connect to room ${event.room.name} with exception: ${event.exception}');
_completer.completeError(event.exception);
}

Future<Room> connectToRoom() async {
var connectOptions = ConnectOptions(
accessToken,
roomName: roomName,
region: region,                       // Optional region.
preferAudioCodecs: [OpusCodec()],     // Optional list of preferred AudioCodecs
preferVideoCodecs: [H264Codec()],     // Optional list of preferred VideoCodecs.
audioTracks: [LocalAudioTrack(true)], // Optional list of audio tracks.
dataTracks: [
LocalDataTrack(
DataTrackOptions(
ordered: ordered,                      // Optional, Ordered transmission of messages. Default is `true`.
maxPacketLifeTime: maxPacketLifeTime,  // Optional, Maximum retransmit time in milliseconds. Default is [DataTrackOptions.defaultMaxPacketLifeTime]
maxRetransmits: maxRetransmits,        // Optional, Maximum number of retransmitted messages. Default is [DataTrackOptions.defaultMaxRetransmits]
name: name                             // Optional
),                                // Optional
),
],                                    // Optional list of data tracks
videoTracks([LocalVideoTrack(true, CameraCapturer(CameraSource.FRONT_CAMERA))]), // Optional list of video tracks. 
);
_room = await TwilioProgrammableVideo.connect(connectOptions);
_room.onConnected.listen(_onConnected);
_room.onConnectFailure.listen(_onConnectFailure);
return _completer.future;
}

Handle Connected Participants的代码段

// 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');
