基本上，我想显示一个迷你播放器，每当一个网格被按下，它的细节应该匹配的瓷砖被按下。
class SongJBI extends StatefulWidget {
@override
State<SongJBI> createState() => SongJBIState();
}
class SongJBIState extends State<SongJBI> {
@override
final List<SongModel> sjmodel = [
SongModel(
id: 1,
name: 'rockstar(feat. 21 Savage)',
artist: 'Post Malone',
image: Image.asset('assets/rockstar.jpg'),
),
SongModel(
id: 2,
name: 'My Ordinary Life',
artist: 'The Living Tombstone',
image: Image.asset('assets/mol.jpg'),
),
SongModel(
id: 3,
name: 'House of Memories',
artist: 'Panic! At the Disco',
image: Image.asset('assets/ho.jpg'),
),
SongModel(
id: 4,
name: 'After Dark',
artist: 'Mr. Kitty',
image: Image.asset('assets/ad.jpg'),
),
];
Widget build(BuildContext context) {
return SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: sjmodel.map((smo) {
final data = SongModel(
id: smo.id,
name: smo.name,
artist: smo.artist,
image: smo.image,
);
return GridTile(
child: GestureDetector(
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Song_Screen(recdata: data),
),
);
},
child: GestureDetector(
child: Container(
padding: EdgeInsets.all(10),
child: Column(
children: [
Container(
child: smo.image,
width: 150,
height: 150,
),
Container(
child: Text(
smo.name,
style: TextStyle(
color: Colors.white,
),
),
),
Container(
child: Text(
smo.artist,
style: TextStyle(
color: Colors.white,
),
),
),
],
),
),
),
));
}).toList()),
);
}
}数据最初显示在歌曲屏幕上，但我希望迷你播放器根据点击来更改其数据，以便当歌曲屏幕最小化时，迷你播放器会呈现按下的歌曲网格的详细信息。
这是歌曲屏幕的代码：
import 'package:flutter/material.dart';
import 'package:spotify_clone/Models/song_model.dart';
import 'package:spotify_clone/Widgets/song_recommend.dart';
class Song_Screen extends StatelessWidget {
final SongModel recdata;
Song_Screen({required this.recdata});
@override
double _sliderValue = 0;

}这是迷你播放器的代码，当按下歌曲块并将歌曲屏幕最小化后，它会弹出
import 'package:flutter/material.dart';
class Mini_Player extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Container(
height: 70,
child: Card(

}我真的很糟糕的状态部件和setstate所以请帮助我
这是主屏幕上的迷你播放器和songtile等
