如何解决收音机开始但它并没有停止当我在项目中切换页面时它不会停止

我希望在页面之间切换时停止收音机。我第一次按下停止和启动按钮时它起作用，但是当我想停止时再次按下它时它不会停止。收音机一直开着，从不关掉。当我完全关闭应用程序时，收音机就会停止。我想在同一个按钮上进行停止和恢复操作，我希望在页面之间切换时停止。怎么解决？

代码在这里：

import 'package:Flutter/material.dart';
import 'package:Flutter_radio/Flutter_radio.dart';
class RadioSayfasi extends StatefulWidget {
  @override
  _RadioSayfasiState createState() => _RadioSayfasiState();
}

class _RadioSayfasiState extends State<RadioSayfasi> {
  String url= "https://player.web.tr/listen/d695bfdfb2710f7c53feb05550da66ef";

  bool isPlaying= false;
  bool isVisible= true;
  
  @override
  void initState() {
    // Todo: implement initState
    super.initState();
    audioStart();
  }

  Future <void> audioStart() async {
    await FlutterRadio.audioStart();
    print("Radio Başladı");
  }
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
        title: 'IndieXL Online Radio',debugShowCheckedModeBanner: false,home: new Scaffold(
          appBar: new AppBar(
            title: const Text('FM Radio'),backgroundColor: Colors.blueGrey.shade900,centerTitle: true,),body: Container(
            color: Colors.blueGrey.shade900,child: new Column(
              children: <Widget>[
                Expanded(
                  flex: 7,child: Icon(
                    Icons.radio,size: 250,color: Colors.white,Expanded(
                  flex: 2,child: Padding(
                    padding: const EdgeInsets.only(right: 40),child: Align(
                      alignment: FractionalOffset.center,child: IconButton(icon: isPlaying? Icon(
                        Icons.pause_circle_outline,size: 80,)
                          : Icon(
                        Icons.play_circle_outline,onpressed: (){
                          setState(() {
                            FlutterRadio.play(url: url);
                            isPlaying = !isPlaying;
                            isVisible = !isVisible;
                            print("tıkladı");
                          });
                        },SizedBox(height: 50,)
              ],));
  }

}

解决方法

我猜你提到的图书馆，https://github.com/thyagoluciano/flutter_radio

要在离开屏幕时停止广播流，只需覆盖 dispose 方法

https://github.com/thyagoluciano/flutter_radio/blob/master/lib/flutter_radio.dart#L67

@action
dispose() async {
    await FlutterRadio.stop();
}

开始或暂停广播流 https://github.com/thyagoluciano/flutter_radio/blob/master/lib/flutter_radio.dart#L22

onPressed: (){ 
    setState(() { 
        //FlutterRadio.play(url: url); 
        FlutterRadio.playOrPause(url: url); 
        isPlaying = !isPlaying; 
        isVisible = !isVisible; 
        print("tıkladı"); 
    }); 
},
