ThumbnailSet(id.value),

For playlist : https://www.youtube.com/playlist?list=PLP_uM5nc6HCAu1X-VJznlTU-iWRbw0on4
https://img.youtube.com/vi/PLP_uM5nc6HCAu1X-VJznlTU-iWRbw0on4/maxresdefault.jpg (or any variant)
returns no image.
Solution is to probably get the first video url, as i couldn't find any alt

implementing either https://github.com/Tyrrrz/YoutubeExplode/pull/391/files
or use oembed

Waiting for your thoughts on this and potential fix

I implemented a custom solution that requires parsing the html page.

https://github.com/khaled-0/Syncara/blob/fdfa6de4e89e5633262ab1597edf1e3f47c68876/lib/provider/library_provider.dart#L74

  // Parse html page to retrieve custom thumbnails
  static Future<Playlist> _playlistWithThumbnail(
    Playlist playlist,
  ) async {
    try {
      final response = await yt.YoutubeHttpClient().getString(
        playlist.externalURL,
      );
      final img = parse(response).querySelectorAll("meta[property='og:image']");

      final max = img.last.attributes["content"]!;
      final std = (img.elementAtOrNull(1) ?? img.first).attributes["content"]!;

      return playlist.copyWith(thumbnailStd: std, thumbnailMax: max);
    } catch (_) {
      return playlist;
    }
  }
