How can I load song image in notification using audio_service and just_audio

Here's my code.

  MediaItem item = MediaItem(
      id: song.id.toString(),
      title: song.title,
      duration: Duration(milliseconds: song.duration ?? 0),
      album: song.album,
      artist: song.artist,
      artUri: Uri.parse(song.uri!),//   content://media/external/audio/media/36
      extras: {'url': song.uri!});

The console was:
