paging
A Flutter package for paginating a list view
Installation
Add this to your package's pubspec.yaml file
dependencies:
...
paging: ^latest.version.here
Usage
First import paging.dart
import 'package:paging/paging.dart';
Simple to use. You can pass a type <T> as a parameter to the widget, by default dynamic is assumed.
There are two required parameters:
- pageBuilder: requires a Future of List<T> and gives you the current size of list
- itemBuilder: requires a widget and gives you the item of type <T> to be displayed
// mocking a network call
Future<List<String>> pageData(int previousCount) async {
await Future.delayed(Duration(seconds: 0, milliseconds: 2000));
List<String> dummyList = List();
if (previousCount < 30) {
// stop loading after 30 items
for (int i = previousCount; i < previousCount + _COUNT; i++) {
dummyList.add('Item $i');
}
}
return dummyList;
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Pagination List')),
body: Pagination<String>(
pageBuilder: (currentSize) => pageData(currentSize),
itemBuilder: (index, item){
return Container(
color: Colors.yellow,
height: 48,
child: Text(item),
);
},
),
);
}
