flutter - Flutter auido_service 网络连接不好

问题描述

下午好，请帮忙处理audio_service插件，我不明白如何制作一个在加载音频时互联网连接不佳时不会移动的滑块

StreamBuilder _timeLineSlider(double playbackSlider) {
return StreamBuilder<MediaState>(
    stream: _mediaStateStream,
    builder: (context, snapshot) {
      final mediaState = snapshot.data;

      _playEnded(
        mediaState?.position.inSeconds ?? 0,
        mediaState?.mediaItem?.duration?.inSeconds ?? 0
      );

      Duration _duration = mediaState?.position ?? Duration.zero;

      return SeekBar(
        duration: mediaState?.mediaItem?.duration ?? Duration.zero,
        position: _duration.inSeconds > 0 ? _duration : Duration.zero,
        onChangeEnd: AudioService.seekTo
      );
    }
); }

我就是这样做的，但是如果连接不好，滑块会移动而音频不播放

我得到这样的职位

Stream<MediaState> get _mediaStateStream =>
  Rx.combineLatest2<MediaItem?, Duration, MediaState>(
      AudioService.currentMediaItemStream,
      AudioService.positionStream,
          (mediaItem, position) => MediaState(mediaItem, position));
