How to play local mp3 file with audioplayer 0.2.0 in Flutter.

pubspec.yaml

flutter:
    assets:
    - sounds/music.mp3

main.dart

Future<ByteData> loadAsset() async {
    return await rootBundle.load('sounds/music.mp3');
}

// FIXME: This code is not working.
Future playLocal() async {
    final result = await audioPlayer.play(loadAsset());
    if (result == 1) setState(() => playerState = PlayerState.playing);
}

Can I get local assets path from rootBundle? Can I pay audio from ByteData on audioPlayer?

The audioplayer plugin currently only supports network paths and files. You can move an asset to a temporary folder and play it with this code:

import 'package:path_provider/path_provider.dart';

...

final file = new File('${(await getTemporaryDirectory()).path}/music.mp3');
await file.writeAsBytes((await loadAsset()).buffer.asUint8List());
final result = await audioPlayer.play(file.path, isLocal: true);
