How to implement Nested ListView in Flutter?
For child ListView, use that parameter:
shrinkWrap: true,
physics: ClampingScrollPhysics(),
Adding physics: ClampingScrollPhysics()
and shrinkWrap: true
did the trick for me.
sample code:
@override
Widget build(BuildContext context) {
return Container(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Expanded(
child: ListView.builder(
shrinkWrap: true,
itemCount: 123,
itemBuilder: (BuildContext context, int index) {
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text('Parent'),
ListView.builder(
itemCount: 2,
physics: ClampingScrollPhysics(),
shrinkWrap: true,
itemBuilder: (BuildContext context, int index) {
return Text('Child');
}),
],
);
}),
)
],
),
);
}
If you want to have the inner ListView be scrollable independently of the main scroll view, you should use NestedScrollView
. Otherwise, use a CustomScrollView
.
Here is some code illustrating the NestedScrollView
approach.
import 'package:flutter/material.dart';
void main() {
runApp(new MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new Scaffold(
body: new NestedScrollView(
headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
return <Widget>[
new SliverAppBar(
pinned: true,
title: new Text('Flutter Demo'),
),
];
},
body: new Column(
children: <Widget>[
new FlutterLogo(size: 100.0, colors: Colors.purple),
new Container(
height: 300.0,
child: new ListView.builder(
itemCount: 60,
itemBuilder: (BuildContext context, int index) {
return new Text('Item $index');
},
),
),
new FlutterLogo(size: 100.0, colors: Colors.orange),
],
),
),
);
}
}
Screenshot:
Code:
var _container = Container(
height: 200,
color: Colors.blue,
margin: EdgeInsets.symmetric(vertical: 10),
);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("ListView")),
body: Padding(
padding: const EdgeInsets.all(40.0),
child: ListView( // parent ListView
children: <Widget>[
_container,
_container,
Container(
height: 200, // give it a fixed height constraint
color: Colors.teal,
// child ListView
child: ListView.builder(itemBuilder: (_, i) => ListTile(title: Text("Item ${i}"))),
),
_container,
_container,
_container,
],
),
),
);
}
For inner Listview I have just added below code and it solved for me
shrinkWrap: true,
physics: ScrollPhysics(),
