我有一个简单的flutter应用程序,当点击狗的Circle头像时会发出吠叫声。如果我按照以下方式将音频文件保存在pubspec.yaml文件中,那么它将起作用
flutter:
uses-material-design: true
assets:
- assets/
- images/
化身用FlatButton控件包装,并且onPressed方法是这样的:
onPressed: (){
audioCache.play('bark.mp3');
},
但是,当我将音频文件保存在“音频”目录中时,不会发生相同的情况,
flutter:
uses-material-design: true
assets:
- audios/
- images/
和onPressed方法:
onPressed: (){
audioCache.play('audios/bark.mp3');
},
当我使用第二种方法保留音频文件时,会出现以下错误:
Cannot find asset: "assets/audios/bark.mp3"
可能是什么问题?
这是main.dart中的以下代码
import 'package:flutter/material.dart';
import 'package:audioplayers/audio_cache.dart';
import 'package:audioplayers/audioplayers.dart';
// The main function is the starting point.
void main() {
runApp(MyApp());
}
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
AudioCache audioCache;
@override
void initState() {
// TODO: implement initState
super.initState();
audioCache = AudioCache();
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
backgroundColor: Colors.indigo[300],
body: SafeArea(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
FlatButton(
onPressed: (){
audioCache.play('bark.mp3');
},
child: CircleAvatar(

),

],

);
}
}
下面有目录树图像。请注意,audios和images文件夹位于根目录中。图像工作正常,但音频不工作。

AudioPlayers被硬编码到“ assets \”文件夹,因此您不能将音频文件放入另一个根文件夹。

我认为您遗漏了一些东西,尝试使用 OnPressed 方法
