API

FlutterAudioQuery

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();

Getting all artist available on device storage:

List<ArtistInfo> artists = await audioQuery.getArtists(); // returns all artists available

artists.forEach( (artist){
      print(artist); /// prints all artist property values
    } );

Getting albums data:

 /// 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
    });

Getting genre data

/// 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 songs data

/// 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 playlist data

    /// 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]);

Sorting queries

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...

Searching

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");
