How to make detailed screen that has audio in it after user clicked on the listview item

How do I make detail screen that has an audio in each of them. Do i have to declare for each audio player for each listview item? May anyone can give me insights to make it simpler as possible? Btw, i use just_audio plugin. Thank you in advance to anyone who can help me :)

This is the image of the listview

This is the image of the detail screen

//the declaration

late AudioPlayer player;
late AudioPlayer player2;

  @override
  void initState() {
    super.initState();
    player = AudioPlayer();
    player2 = AudioPlayer();
  }

  @override
  void dispose() {
    player.dispose();
    player2.dispose();
    super.dispose();
  }

//audio player button that I intended to put in detail screen for each listview item

FlatButton(
                onPressed: () async {
                  try {
                    await player.setAsset("assets/audio/mim dengung.mp3");
                    player.play();
                  } on PlayerException catch (e) {
                    print("Error code: ${e.code}");
                    print("Error message: ${e.message}");
                  } on PlayerInterruptedException catch (e) {
                    print("Connection aborted: ${e.message}");
                  } catch (e) {
                    print(e);
                  }
                },
                padding: EdgeInsets.symmetric(horizontal: 50),
                shape: StadiumBorder(
                    side: BorderSide(color: Colors.white54, width: 2)),
                child: Container(

                  decoration: ShapeDecoration(
                    color: Colors.amber,
                    shape: StadiumBorder(),
                  ),
                  child: Row(
                    children: <Widget>[
                      Icon(Icons.volume_up_outlined),

    You are already passing title, longText and image to your DetailScreen inside an Item. So you can just add the audio to Item as well and have access to that inside your DetailScreen. Then you can move the audio player logic to your DetailScreen and just use one audio player which would play the audio based on item.audio.
