How to play local mp3 file with audioplayer plugin in Flutter

A way that worked for me was to create the assets file and load the mp3 file in to the directory.

Then load the file using the Future

 AudioPlayer audio = await AudioCache.play("filetobeloaded.mp3");

I have just created a repo in github that uses audioplayers plugin to stream local mp3 files. This player can seek, pause, stop and play local audio

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);
