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),
                 );
        },
      ),
    );
  }
