[isa-sabbagh]

Describe the bug publishDate and uploadDate in playlist return null all the time

void _getList() async {
    setState(() => _isLoading = true);
    try {
      var yt = YoutubeExplode();

      // Get playlist metadata.
      var playlist = await yt.playlists.get('https://www.youtube.com/playlist?list=PLDoPjvoNmBAzH72MTPuAAaYfReraNlQgM');

      await for (var video in yt.playlists.getVideos(playlist.id)) {
        print(video.publishDate); // retren null 
        setState(() {
          _videosList.add(YoutubeVideo(
            id: video.id.toString(),
            image: video.thumbnails.lowResUrl,
            title: video.title,
            url: video.url,
            videoPublishedAt: video.publishDate ?? video.uploadDate ?? DateTime.now(),
          ));
        });
      }
    } finally {
      setState(() => _isLoading = false);
    }
  }

That is the intended behavior unfortunately; as you can see in the playlist page youtube doesn't provide any publish or upload date.
