Can anybody tell me how to use this latest library to play a single audio file present in the asset folder of the root of flutter? The code sample of this library on pub.dev is quite difficult to understand

CodePudding user response：

First create an instance of AudioPlayer class.

final player = AudioPlayer();

then add asset file in player.setSource method.

await player.setSource(AssetSource('sounds/coin.wav'));

It's as simple as the following snippet. Where click.mp3 is inside the assets folder.

final player = AudioPlayer();
player.play(AssetSource('click.mp3')),

A complete example:

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

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
      debugShowCheckedModeBanner: false,
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  AudioPlayer? _player;

  @override
  void dispose() {
    _player?.dispose();
    super.dispose();
  }

  void _play() {
    _player?.dispose();
    final player = _player = AudioPlayer();
    player.play(AssetSource('click.mp3'));
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: const [
            Text(
              'Click on the play button to play a sound',
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _play,
        tooltip: 'Play',
        child: const Icon(Icons.volume_up),
      ),
    );
  }
}
