A Flutter plugin, Android only at this moment, that allows you query for audio metadata info about artists, albums, songs audio files and genres available on device storage. All work is made using Android native MediaStore API with ContentResolver API and query methods run in background thread. AndroidX support it's OK!
Note: This plugin is under development, Works in Android devices only and some APIs are not available yet. Feedback, pull request, bug reports and suggestions are all welcome!
Feel free to help!

To use this plugin, add flutter_audio_query as a dependency in your pubspec.yaml file. For example:
dependencies:
flutter_audio_query: "^0.3.5+6"To get get audio files metadata info you just need FlutterAudioQuery object instance.
///you need include this file only.
import 'package:flutter_audio_query/flutter_audio_query.dart';
/// create a FlutterAudioQuery instance.
final FlutterAudioQuery audioQuery = FlutterAudioQuery();List<ArtistInfo> artists = await audioQuery.getArtists(); // returns all artists available
artists.forEach( (artist){
print(artist); /// prints all artist property values
} ); /// getting all albums available on device storage
List<AlbumInfo> albumList = await audioQuery.getAlbums();
/// getting all albums available from a specific artist
List<AlbumInfo> albums = await audioQuery.getAlbumsFromArtist(artist: artist.name);
albums.forEach( (artistAlbum) {
print(artistAlbum); //print all album property values
});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,
);
}) :
// or you can load image from File path if available.
Image.file( File( artist.artistArtPath ) )
/// getting all genres available
List<GenreInfo> genreList = audioQuery.getGenres();
genreList.foreach( (genre){
/// getting all artists available from specific genre.
await audioQuery.getArtistsFromGenre(genre: genre.name);
/// getting all albums which appears on genre [genre].
await audioQuery.getAlbumsFromGenre(genre: genre.name);
/// getting all songs which appears on genre [genre]
await audioQuery.getSongsFromGenre(genre: genre.name);
} );/// getting all songs available on device storage
List<SongInfo> songs = await audioQuery.getSongs();
albumList.foreach( (album){
/// getting songs from specific album
audioQuery.getSongsFromAlbum(album: album.name);
} ); /// getting all playlist available
List<PlaylistInfo> playlist = await audioQuery.getPlaylists();
/// Getting playlist songs
List<SongInfo> songs = await audioQuery.getSongsFromPlaylist(playlist: playlist[0]);
/// adding songs into a specific playlist
PlaylistInfo updatedPlaylist = await playlist[0].addSong(song: songs[2] );
//removing song from a specific playlist
updatedPlaylist = await updatedPlaylist.removeSong(song: songs[2]);You can also define a sort query constraint to get the data already sorted using sort enums.ArtistSortType, AlbumSortType, SongSortType, GenreSortType, PlaylistSortType.
/// Getting albums sorted by most recent year first
audioQuery.getAlbums(sortType: AlbumSortType.MOST_RECENT_YEAR )
/// getting artists sorted by number of songs
audioQuery.getArtits(sortType: ArtistSortType.MORE_TRACKS_NUMBER_FIRST);
/// and more...You can search using search methods.
///searching for albums that title starts with 'a'
List<AlbumInfo> albums = await audioQuery.searchAlbums(query "a");
/// searching for songs that title starts with 'la'
List<SongInfo> songs = await audioQuery.searchSongs(query: "la");Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
Please make sure to update tests as appropriate.
