In Flutter, you can implement pull-to-refresh by using the RefreshIndicator
widget. The RefreshIndicator
widget is a Material Design pull-to-refresh indicator that can be used to reload the contents of a ListView
.
Here is an example of how you can implement pull-to-refresh in Flutter:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: RefreshIndicator(
onRefresh: () async {
// Reload the data here
return null;
},
child: ListView(
children: [
// Your list items go here
],
),
),
),
);
}
}
In this example, the RefreshIndicator
widget is used to wrap a ListView
. When the user pulls down on the ListView
, the RefreshIndicator
will appear and animate, indicating that the contents of the ListView
are being reloaded. The onRefresh
callback is called to reload the data, and you can implement this callback to reload the contents of the ListView
.
