flutter_easy_refresh

English | 中文

Just like the name, EasyRefresh can easily implement pull-down refresh and pull-up load on Flutter applications. It supports almost all Flutter Scrollable widgets. Its function is very similar to Android's SmartRefreshLayout, and it also absorbs the advantages of many third-party libraries. EasyRefresh integrates various styles of Header and Footer, but it has no limitations, you can easily customize it. Using Flutter's powerful animations, even just a simple control can be done. The goal of EasyRefresh is to create a powerful, stable and mature pull-to-refresh framework for Flutter.

Companion Packages

For pagination helpers, use the standalone easy_paging package.

import 'package:easy_paging/easy_paging.dart';
import 'package:easy_refresh/easy_refresh.dart';

Sample implementation: example/lib/page/sample/paging_page.dart

Sample

1. Default constructor

• In the child scope, all scrolling components will share one physics. If there is scroll nesting, use EasyRefresh.builder or set the scope with ScrollConfiguration

  EasyRefresh(
    onRefresh: () async {
      ....
    },
    onLoad: () async {
      ....
    },
    child: ListView(),
  );

2. Builder constructor

  EasyRefresh.builder(
    onRefresh: () async {
      ....
      return IndicatorResult.success;
    },
    onLoad: () async {
      ....
    },
    childBuilder: (context, physics) {
      return ListView(
        physics: physics,
      );
    },
  );

3. Indicator locate

  EasyRefresh(
    header: Header(
      position: IndicatorPosition.locator,
    ),
    footer: Footer(
      position: IndicatorPosition.locator,
    ),
    onRefresh: () async {
      ....
    },
    onLoad: () async {
      ....
      return IndicatorResult.noMore;
    },
    child: CustomScrollView(
      slivers: [
        SliverAppBar(),
        const HeaderLocator.sliver(),
        ...
        const FooterLocator.sliver(),
      ],
    ),
  );

4. Use controller

  EasyRefreshController _controller = EasyRefreshController(
    controlFinishRefresh: true,
    controlFinishLoad: true,
  );
  ....
  EasyRefresh(
    controller: _controller,
    onRefresh: () async {
      ....
      _controller.finishRefresh();
      _controller.resetFooter();
    },
    onLoad: () async {
      ....
      _controller.finishLoad(IndicatorResult.noMore);
    },
    ....
  );
  ....
  _controller.callRefresh();
  _controller.callLoad();

5. Specify Header and Footer

  EasyRefresh(
    header: MaterialHeader(),
    footer: MaterialFooter(),
    child: ListView(),
    ....
  );
  // Global
  EasyRefresh.defaultHeaderBuilder = () => ClassicHeader();
  EasyRefresh.defaultFooterBuilder = () => ClassicFooter();

6. NestedScrollView

  EasyRefresh.builder(
    header: MaterialHeader(
      clamping: true,
    ),
    onRefresh: () async {
      ....
    },
    onLoad: () async {
      ....
    },
    childBuilder: (context, physics) {
      return NestedScrollView(
        physics: physics,
        body: ListView(
          physics: physics,
        );
      );
    },
  );
  // or
  EasyRefresh.builder(
    header: MaterialHeader(
      clamping: true,
      position: IndicatorPosition.locator,
    ),
    onRefresh: () async {
      ....
    },
    onLoad: () async {
      ....
    },
    childBuilder: (context, physics) {
      return NestedScrollView(
        physics: physics,
        headerSliverBuilder: (context, innerBoxIsScrolled) {
          return [
            const HeaderLocator.sliver(clearExtent: false),
            ....
          ];
        },
        body: ListView(
          physics: physics,
        );
      );
    },
  );
