You can use

and add a reference in your yaml file and get dependencies

  assets:
    - assets/audio/

import 'package:audioplayers/audioplayers.dart';
import 'package:flutter/material.dart';

class AudioManagerExample extends StatefulWidget {
  const AudioManagerExample({required this.audioName, Key? key}) : super(key: key);

  final String audioName;

  @override
  _AudioManagerExampleState createState() => _AudioManagerExampleState();
}

class _AudioManagerExampleState extends State<AudioManagerExample> {
  AudioPlayer audioPlayer = AudioPlayer();
  late AudioCache audioCache;

  @override
  void initState() {
    audioCache = AudioCache(fixedPlayer: audioPlayer);
    audioCache.load('audio/${widget.audioName}.mp3');
    super.initState();
  }

  @override
  void dispose() {
    audioCache.clearAll();
    audioPlayer.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        ElevatedButton(
          onPressed: () {
            setState(() {
              audioCache.play('audio/${widget.audioName}.mp3');
            });
          },
          child: Text('Play ${widget.audioName}'),
        ),
        ElevatedButton(
          onPressed: () {
            setState(() {
              audioPlayer.pause();
            });
          },
          child: Text('Pause ${widget.audioName}'),
        ),
        ElevatedButton(
          onPressed: () {
            setState(() {
              audioPlayer.stop();
            });
          },
