Feature/get artwork

[sc4v3ng3r]

Getting artwork on Android >= Q:

Since Android API level 29 ALBUM_ART constant is deprecated and plus scoped storage approach we can't load artwork from absolute image path. So if your app is running over Android API >= 29 you will get all artwork fields with null. To fetch images on these API levels you can use getArwork method.

 /// detecting, loading and displaying an artist artwork.

 ArtistInfo artist // assuming a non null instance

 // check if artistArtPath isn't available.

 (artist.artistArtPath == null)

    ? FutureBuilder<Uint8List>(
      future: audioQuery.getArtwork(

        type: ResourceType.ARTIST, id: artist.id),
        builder: (_, snapshot) {
          if (snapshot.data == null)
            return Container(
              height: 250.0,
              child: Center(
                child: CircularProgressIndicator(),
              ),
            );

            return CardItemWidget(
              height: 250.0,
              title: artist.name,
              subtitle: "Number of Albums: ${artist.numberOfAlbums}",
              infoText: "Number of Songs: ${artist.numberOfTracks}",
              // The image bytes
              // You can use Image.memory widget constructor 
              // or MemoryImage image provider class to load image from bytes
              // or a different approach.
              rawImage: snapshot.data,
            );
