MissingPluginException(No implementation found for method init on channel com.ryanheise.just_audio.methods)

Question

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)

Solution 1

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.

Solution 2

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.

It didn't help. I'm getting the same result.

Try to change the audio package which you are using.

[Muhammad Ashir]

or maybe you can try to update the version

[Sadikul Haque Sadi]

Yeah. After adding the just_audio_libwinmedia and libwinmedia, the previous error has been solved
