问题描述
我是Ffltter开发的新手，我陷入了一个程序中，我想在按下TextButton()时播放音频文件，但在按下该按钮时没有播放音频，并且在调试控制台中收到了一条巨大的消息。有谁能帮我检测一下这个问题吗？
这是我在调试控制台中收到的消息：

这是我的代码：
import 'package:just_audio/just_audio.dart';
import 'package:flutter/material.dart';
void main() {
runApp(Xylophone());
}
class Xylophone extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: SafeArea(
child: Center(
child: TextButton(onPressed: ()async{
final player = AudioPlayer();
await player.setAsset('assets/assets_note1.wav');
},
child:Text('Click me'),
),
),
),
),
);
}
}
推荐答案
将此依赖项添加到pubspec.yaml文件Assets_AUDIO_Player：^3.0.3+3
创建playSound函数，如
playSound() async {
AssetsAudioPlayer audioPlayer = AssetsAudioPlayer();
audioPlayer.open(Audio('assets/bells.mp3'));
}
内部小工具创建按钮
TextButton(
onPressed: () => playSound(),
child: Text('Play'),
),
