Flutter Scrolling widget inside a Scrolling widget - dart

Question

Hello I am building this page https://cdn.discordapp.com/attachments/460823618805563392/526802427836366848/unknown.png
ListView.builder(
shrinkWrap: true,
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return new Column(
children: <Widget>[
new RopSayac(MediaQuery.of(context).size.width),
stackvideos(),
],
);
},
)
This is my first listView and there is another listview in stack videos too.
new CustomScrollView(
slivers: <Widget>[
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return new VideoTile();
},
),
),
],
),
Video tile is ordinary component which returns an image and text
My full code
import 'package:flutter/material.dart';
import '../Theme.dart' as Theme;
import '../Components/ropSayac.dart';
import '../Components/Stackvideostile.dart';
class Ropo extends StatelessWidget {
Widget didvideomounted(bool asd) {
if (asd == true) {
return new Text("video");
} else
return new Container(
width: 226.0,
height: 226.0,
decoration: new BoxDecoration(
shape: BoxShape.circle,
border: new Border.all(
width: 5.0, color: Theme.Colors.roportajheroborder)),
);
}
Widget stackvideos() {
return new Container(
decoration: new BoxDecoration(
color: Theme.Colors.tabbarbackground,
borderRadius: BorderRadius.all(Radius.circular(8.0)),
),
margin: EdgeInsets.only(top: 40.0, bottom: 10.0),
width: 358.0,
height: 343.0,
child: Column(
children: <Widget>[
Container(
// Üstteki bar
width: 358.0,
height: 46.0,
decoration: new BoxDecoration(
color: Theme.Colors.stackvideostopbar,
borderRadius: BorderRadius.all(Radius.circular(8.0)),
boxShadow: <BoxShadow>[
new BoxShadow(
color: Colors.black12,
blurRadius: 3.0,
offset: new Offset(0.0, 7.0),
),
],
),
child: Center(
child: new Text(
"BENCE Bİ’ ÖNCEKİLERE DE GÖZ AT",
style: Theme.TextStyles.stackvideotitle,
),
),
), //üstteki bar bitti
new CustomScrollView(
slivers: <Widget>[
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return new VideoTile();
},
),
),
],
),
],
),
);
}
List<String> lists = ["asdas","adadsa"];
#override
Widget build(BuildContext context) {
return Container(
color: Theme.Colors.pagebackground,
child: new Stack(
children: <Widget>[
new Container(
margin: EdgeInsets.only(left: 30.0, top: 37.0),
child: Image.asset(
"assets/k.png",
fit: BoxFit.cover,
),
),
ListView.builder(
shrinkWrap: true,
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return new Column(
children: <Widget>[
new RopSayac(MediaQuery.of(context).size.width),
stackvideos(),
],
);
},
)
//new Image.asset("name"),
],
),
);
}
}
And This is the error log

You can take advantage of the CustomScrollView widget and change your layout :
Change this:
ListView.builder(
shrinkWrap: true,
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return new Column(
children: <Widget>[
new RopSayac(MediaQuery.of(context).size.width),
stackvideos(),
],
);
},
)
new CustomScrollView(
slivers: <Widget>[
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return new VideoTile();
},
),
),
],
),
To this:
CustomScrollView(
slivers: <Widget>[
SliverToBoxAdapter(
child: RopSayac(MediaQuery.of(context).size.width),
),
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return new VideoTile();
},
),
),
],
)
