A Flutter package for paginating a list view

[![pub package](https://img.shields.io/pub/v/paging.svg?style=popout)](https://pub.dartlang.org/packages/paging)

## Installation

Add this to your package's pubspec.yaml file

```yaml
dependencies:
  ...
  paging: ^latest.version.here
```

## Usage
First import paging.dart

```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

```dart

// 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),
                 );
        },
      ),
    );
  }
```
