Uint8List support for arturi

[HadiWannous]

Feature proposal

i need the mediaItem support for uint8list as audio artwork...there is no working way to parse it in uri form

Motivating use case(s)

supporting fetched data from audio file to make the artwork appear in the notification

You can write the data to a file and then use a file URI.

Currently working on an implementation using a file and the following error has occured:

D/HWUI    (12310): --- Failed to create image decoder with message 'unimplemented'

My code looks like this:

final File file = File(path);
file.writeAsBytesSync(data.buffer.asUint8List());
MediaItem item = MediaItem(
      id: song.id.toString(),
      album: song.album,
      title: song.title,
      artist: song.artist,
      duration: Duration(milliseconds: song.duration ?? 0),
      artUri: file.uri,
);
mediaItem.add(item);

Any idea why this wouldn't work? Or why the error? The same thing works on Linux, but on Android it raises this error.
