rtcEngine$onSimulcastSubscribeFallback$info$event method

FutureOr<void> rtcEngine$onSimulcastSubscribeFallback$info$event(dynamic engine, dynamic streamId, dynamic info, dynamic event,)

@detail callback @author panjian.fishing @brief 音视频流因网络环境变化等原因发生回退，或从回退中恢复时，触发该回调。 @param engine 当前 ByteRTCEngine 实例 @param streamId 流 ID @param info 流信息, 参看 ByteRTCStreamInfo{@link #ByteRTCStreamInfo}。 @param event 流切换信息。详见 ByteRTCRemoteStreamSwitchEvent{@link #ByteRTCRemoteStreamSwitchEvent}。
