EndlessListView
The EndlessListView class is a Flutter widget that enables infinite scrolling behavior. It allows for loading more data when the user scrolls to the end of the current list. This widget is useful for displaying large lists of data that may not be available all at once, or for optimizing performance by reducing the amount of data loaded at any given time.
Example Usage
import 'package:flutter/material.dart';
import 'package:endless_list_view/endless_list_view.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'EndlessListView Example',
home: EndlessListViewExample(),
);
}
}
class EndlessListViewExample extends StatefulWidget {
@override
_EndlessListViewExampleState createState() =>
_EndlessListViewExampleState();
}
class _EndlessListViewExampleState extends State<EndlessListViewExample> {
final List<Widget> _items = List.generate(20, (index) => Text('Item $index'));
Future<List<Widget>> _loadMoreData() async {
await Future.delayed(Duration(seconds: 2));
return List.generate(20,
(index) => Text('Item ${index + _items.length} - Loaded asynchronously'));
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('EndlessListView Example'),
),
body: EndlessListView(
initialItems: _items,
onLoadMoreData: _loadMoreData,
),
);
}
}
In this example, we create an EndlessListView widget and provide it with an initial list of 20 items. When the user scrolls to the end of the list, the _loadMoreData function is called, which simulates loading another 20 items asynchronously. These items are then added to the end of the list, and the user can continue scrolling infinitely.
