How to use

To use this plugin, add infinite_pagination as a dependency in your pubspec.yaml file. For example:


Usually we use provider as State Management.

import 'package:infinite_pagination/infinite_pagination.dart';

class Catalog extends InfinitePagination<Chapter> {
      : super(
          fetcher: (int startingIndex, int itemsPerPage) async => 
            startingIndex: startingIndex,
            countPerPage: 10,
            total: 142,
            mock: (i) => Chapter(i),
            delay: 500,

Widget build(BuildContext context) {
    return ChangeNotifierProvider(
      create: (_) => Catalog(),
      child: Selector<Catalog, int>(
          selector: (context, catalog) => catalog.itemCount,
          builder: (context, itemCount, child) => ListView.builder(
            key: PageStorageKey('ListView'),
            itemCount: itemCount,
            itemBuilder: (context, index) {
              // Every item of the `ListView` is individually listening
              // to the catalog.
              var catalog = Provider.of<Catalog>(context);

              // Catalog provides a single synchronous method for getting
              // the current data.
              var item = catalog.getByIndex(index);

              if (item == null) {
                return LoadingTile();

              return ListTile(
                leading: CircleAvatar(child: Text('${item.i}')),
                title: Text('Chapter #${item.i}'),
                subtitle: Text('subtitle ${item.i}'),
