我得到了一个包含一些错误 url 的 AudioSources 播放列表（返回 400 错误和一些信息）。我使用 ConcatenatingAudioSource 来包装这些音频并传递给 setAudioSource。
当播放器播放错误的 url 音频源时，它会抛出如下内容：

E/ExoPlayerImplInternal(10255): Playback error
E/ExoPlayerImplInternal(10255):   com.google.android.exoplayer2.ExoPlaybackException: Source error
E/ExoPlayerImplInternal(10255):       at com.google.android.exoplayer2.ExoPlayerImplInternal.handleIoException(ExoPlayerImplInternal.java:624)

在这种情况下如何捕捉错误？

到目前为止我试图抓住的东西：

    audioPlayer.playbackEventStream.listen(
      (event) {},
      onError: (Object e, StackTrace stackTrace) {
        print('A stream error occurred: $e');
      },
    );

    audioPlayer.sequenceStream.listen((event) {},
        onError: (Object e, StackTrace stackTrace) {
      print('A sequence error occurred: $e');
    });
    audioPlayer.sequenceStateStream.listen((event) {},
        onError: (Object e, StackTrace stackTrace) {
      print('A sequencestate error occurred: $e');
    });
    audioPlayer.processingStateStream.listen((event) {},
        onError: (Object e, StackTrace stackTrace) {
      print('A processingState error occurred: $e');
    });
    audioPlayer.playerStateStream.listen((event) {},
        onError: (Object e, StackTrace stackTrace) {
      print('A playerStateStream error occurred: $e');
    });
    audioPlayer.playingStream.listen((event) {},
        onError: (Object e, StackTrace stackTrace) {
      print('A playingStream error occurred: $e');
    });
    audioPlayer.bufferedPositionStream.listen((event) {},
        onError: (Object e, StackTrace stackTrace) {
      print('A bufferedPositionStream error occurred: $e');
    });

    try {
      await audioPlayer
         .setAudioSource(_playlist, preload: true)
         .onError((e, stackTrace) {
             print('A player error occurred: $e');
      });
    } catch (e) {
      print("Error loading playlist occurred: $e");
    }

尝试播放并捕获如下错误：

    try {
        // Playback
    } on Exception catch (_) {
        // Error handling
    }
