Is it possible to play a sound from the assets when the user clicks on a button on a home_widget?

[myThorsten]

Hello :)

I am trying to make a home_widget which will play sounds. I successfully implemented your example, the title is changing just fine. Now I want to expand on that. I am usning the package flutter_sound . Here is what I am trying:

import 'dart:io';
import 'dart:math';

import 'package:flutter_sound_lite/flutter_sound.dart';
import 'package:home_widget/home_widget.dart';
import 'package:logger/logger.dart';

import '../../../core/file_helper.dart';

void backgroundCallback(Uri? data) async {
  if (data?.host == 'titleclicked') {
    final greetings = ['Hello', 'Hallo', 'Bonjour', 'Hola', 'Ciao', '哈洛', '안녕하세요', 'xin chào'];
    final selectedGreeting = greetings[Random().nextInt(greetings.length)];

    await HomeWidget.saveWidgetData<String>('title', selectedGreeting);
    await HomeWidget.updateWidget(name: 'HomeWidgetExampleProvider', iOSName: 'HomeWidgetExample');

    final FlutterSoundPlayer player = FlutterSoundPlayer(logLevel: Level.warning);
    player.openAudioSession(); // this line throws the error, await is not necessary since .startPlayer will wait autoatically
    final File file = await FileHelper.assetToFile(assetSource: 'default/woo.aac');
    print(file);
    await player.startPlayer(
      fromURI: file.path,
      codec: Codec.aacADTS,
      sampleRate: 32000,
    );
  }
}

The output I am getting is this:

E/flutter (11630): [ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: MissingPluginException(No implementation found for method resetPlugin on channel com.dooboolab.flutter_sound_player)

Is that even possible?

Thank you, Thorsten
