onVideoFrameSendStateChanged method

FutureOr<void> onVideoFrameSendStateChanged(dynamic streamId, dynamic streamInfo, dynamic user, dynamic state,)

@detail callback @author wangfujun @brief 视频首帧发送状态发生改变时，收到此回调。 @param streamId 流 ID @param streamInfo 流信息，参看 StreamInfo{@link #StreamInfo} @param user 用户信息，参看 RtcUser{@link #RtcUser} @param state 首帧发送状态，详见 FirstFrameSendState{@link #FirstFrameSendState}

Implementation

FutureOr<void> onVideoFrameSendStateChanged(
    dynamic streamId, dynamic streamInfo, dynamic user, dynamic state) async {
  if ($instance == null || $instance is! IRTCEngineEventHandler) {
    return;
  }
  return ($instance
          as IRTCEngineEventHandler)
      .onVideoFrameSendStateChanged
      ?.call(
          streamId.toString(),
          packObject(
              streamInfo,
              () => StreamInfo.fromMap(
                  StreamInfo.deepPackedMapValues(
                      StreamInfo.mapMemberToConstructorParams(streamInfo)))),
          packObject(
              user,
              () => RtcUser.fromMap(RtcUser
                  .deepPackedMapValues(RtcUser.mapMemberToConstructorParams(
                      user)))),
          t_FirstFrameSendState.android_to_code($p_a
              .FirstFrameSendState.values
              .firstWhere((t) => t.$value == state || t.name == state)));
