If the number of children of ConcatenatingAudioSource is too large, there will be performance problems

[itning]

Which API doesn't behave as documented, and how does it misbehave? If set setShuffleModeEnabled = true and ConcatenatingAudioSource has about 1300 children The player will become very lagging.

Minimal reproduction project

Future<void> setSource(List<MusicDataContent> musics, int initIndex) async {
    ConcatenatingAudioSource concatenatingAudioSource =
    ConcatenatingAudioSource(children: []);
    List<AudioSource> children = [];
    for (var music in musics) {
      String musicUrl = HttpHelper.get().getMusicUrl(music.musicId!);
      Uri coverUri = Uri.parse(HttpHelper.get().getCoverUrl(music.musicId!));
      MediaItem mediaItem = MediaItem(
        id: music.musicId!,
        artist: music.singer ?? '',
        title: music.name ?? '',
        artUri: coverUri,
      );
      AudioSource audioSource;
      audioSource = AudioSource.uri(
        Uri.parse(musicUrl),
        tag: mediaItem,
      );
      children.add(audioSource);
    }
    concatenatingAudioSource.addAll(children);
    try {
      _player.setAudioSource(concatenatingAudioSource,
          initialIndex: initIndex);
    }  catch (e) {
      LogHelper.get().error('catch exception', e);
    }
  }

To Reproduce (i.e. user steps, not code) Steps to reproduce the behavior:

1. _player.setShuffleModeEnabled(true);
2. _player.seekToNext()

Error messages

No error message

Expected behavior No lagging behavior

Closing (for similar reasons as before). @itning are you not reading my previous replies to you? I would appreciate valid bug reports, but when you keep posting invalid ones without reading the instructions carefully it actually creates more of a burden for me and does not help.
