如何解决如何以颤动的方式播放前一屏幕的音频？
有一个带有其URL的歌曲列表，我正在使用Assets_Audio_Player来播放来自URL的音频，并且当我在播放流的同一位置添加播放按钮和播放功能时，它将播放歌曲名称。但是我创建了一个播放器，并且想要它，以便在单击歌曲时转到播放器并播放歌曲。
歌曲列表
class AryanaSayeed extends StatefulWidget {
@override
_AryanaSayeedState createState() => _AryanaSayeedState();
}
class _AryanaSayeedState extends State<AryanaSayeed> {
var played = 0;
final assetsAudioPlayer = AssetsAudioPlayer.withId("0");
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Colors.red[500],title: Text('Aryana Sayeed'),centerTitle: true,actions: <Widget>[
Icon(
Icons.search,),SizedBox(width: 10)
],body: StreamBuilder(
stream: Firestore.instance.collection('aryana sayeed').snapshots(),builder: (
context,snapshot,) {
if (snapshot.data == null)
return Center(
child: CircularProgressIndicator(
backgroundColor: Colors.red,valueColor: new AlwaysStoppedAnimation<Color>(Colors.teal),);
return ListView.builder(
itemCount: snapshot.data.documents.length,itemBuilder: (context,index) {
return SingleChildScrollView(
child: Column(
children: <Widget>[
ListTile(
onTap: () {
Navigator.push(
context,MaterialPageRoute(
builder: (context) => Player1(),));
},leading: Icon(
Icons.audiotrack,color: Colors.red,title: Text(
snapshot.data.documents[index]['name'],style: TextStyle(fontFamily: 'Font'),Divider(
thickness: 1,indent: 40,endIndent: 40,],));
});
},);
}
}

解决方法
在歌曲列表文件中，ListTitle小部件下的onTap函数应如下所示：
onTap: () {
Navigator.push(
context,MaterialPageRoute(
builder: (context) => Player1(name: snapshot.data.documents[index]['name'],url: snapshot.data.documents[index]['url']),));
},然后播放器文件应如下所示：
import 'package:flutter/material.dart';
class _PlayerState1 extends StatefulWidget {
String name;
String url;
_PlayerState1({this.name,this.url});
@override
__PlayerState1State createState() => __PlayerState1State();
}
class __PlayerState1State extends State<_PlayerState1> {
final assetsAudioPlayer = AssetsAudioPlayer.withId("0");
@override
Widget build(BuildContext context) {
return Scaffold(
body: GestureDetector(
onTap: () {
try {
await assetsAudioPlayer.open(
Audio.network(widget.url),);
} catch (t) {
//mp3 unreachable
}
},),);
}
}
