fetchStream method

Future<MediaStream?> fetchStream({ String? deviceId, VideoTrackConfig encoderConfig = VideoTrackConfig.h360p_w640p, String facingMode = "user", required CustomMediaDevice mediaDevice, })

Fetch the stream from the device This stream is not managed by the Huddle01 SDK, i.e. it will not be closed by the SDK the user has to close it manually by calling {stream.getTracks().forEach(track => track.stop())} NOTE: using stopTrackOnClose = true while producing will stop the track when producing is stopped

Implementation
