使用AudioPlayers从按钮中播放单个音符

Question

我正在对AudioPlayers软件包进行过时的教程，并尝试在按下按钮时播放单个音符。我无法让它上​​班，有人可以帮忙吗

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

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

class XylophoneApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SafeArea(
          child: Center(
            child: TextButton(
              onPressed: () {
                final player = AudioCache();
                player.play('note1.wav'); //ERROR THAT 'play' method is not valid
              },
              child: Text('Click Me'),
            ),
          ),
        ),
      ),
    );
  }
}

为了从资产中播放声音，您需要一个audioplayer并将资产设置为其。

onPressed: () async {
    final player = AudioPlayer();
    await player.setAsset('note1.wav'); // make sure to add on pubspec.yaml and provide correct path
    player.play();
  }

终于找到了修复程序，问题与新版本的听力播放器有关，而无需导入各种功能

onPressed: () {
   final player = AudioPlayer();
   player.play(AssetSource("note1.wav"));
}
