I am building a desktop application using flutter where I need to play audio files from local storage and for this I am using just_audio flutter package since it supports Windows. But I Couldn't find any examples of it for windows. I have coded something like this-

import 'package:just_audio/just_audio.dart';
...

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> with WidgetsBindingObserver {
  final _player = AudioPlayer();

  @override
  void initState() {
    super.initState();
    ...
    _init();
  }
   
  Future<void> _init() async {
    await _Player.setFilePath('C:/Users/Admin/Downloads/test.wav', preload: true);
  }
  ...

The await call never finishes and I am getting the following error:

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: MissingPluginException(No implementation found for method init on channel com.ryanheise.just_audio.methods)

Hi If you have used some package, then after pub get try to restart app(Not hot restart, build it again) then it will work.

CodePudding user response：

just_audio doesn't include a Windows implementation. As it says in the README, you need to include another package such as just_audio_libwinmedia that provides a Windows implementation of the package.
