ListView Widget has been introduced to reduce the overload of having various layouts performing the same task.
Purpose Of ListView Widget
Most of the time, the dynamic behavior is achieved by changing the contents that are being displayed in the body. So Flutter provides ListView.Builder() constructor which can be used to generate dynamic contents from external sources.
How to add a ListView to a Column Widget In Flutter?
In Flutter, you can add a ListView
widget inside a Column
widget to create a scrollable list of items vertically aligned within a column. Here’s how you can do it:
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'ListView in Column Example',
home: Scaffold(
appBar: AppBar(
title: Text('ListView in Column Example by flutterfever.com'),
),
body: Column(
children: [
// Other widgets can go here before or after the ListView
Text(
'Above ListView',
style: TextStyle(fontSize: 20),
),
Expanded(
child: ListView.builder(
itemCount: 50, // Example number of list items
itemBuilder: (BuildContext context, int index) {
return ListTile(
title: Text('Item $index'),
);
},
),
),
// Other widgets can go here before or after the ListView
Text(
'Below ListView',
style: TextStyle(fontSize: 20),
),
],
),
),
);
}
}
In this example:
- We have a
Column
widget as the body of theScaffold
. - Inside the
Column
, we have added some text widgets and then anExpanded
widget containing aListView.builder
. - The
Expanded
widget allows theListView
to take all the remaining space in the column. - We’re using
ListView.builder
to create a scrollable list with a specified number of items.
Remember to replace the itemCount
and the itemBuilder
with your own data and UI elements according to your application’s requirements. You can customize the appearance of each list item by modifying the itemBuilder
function.
