正如名字一样，EasyRefresh很容易就能在Flutter应用上实现下拉刷新以及上拉加载操作，它支持几乎所有的Flutter滚动组件。它的功能与Android的SmartRefreshLayout很相似，同样也吸取了很多三方库的优点。EasyRefresh中集成了多种风格的Header和Footer，但是它并没有局限性，你可以很轻松的自定义。使用Flutter强大的动画，甚至随便一个简单的控件也可以完成。EasyRefresh的目标是为Flutter打造一个强大，稳定，成熟的下拉刷新框架。

特点功能:

  • 支持所有的滚动组件
  • 滚动物理作用域，精确匹配滚动组件
  • 集成多个炫酷的 Header 和 Footer
  • 支持自定义样式，实现各种动画效果
  • 支持下拉刷新、上拉加载(可使用控制器触发和结束)
  • 支持指示器位置设定，结合监听器也放置在任何位置
  • 支持页面启动时刷新，并自定义视图
  • 支持安全区域，不再有遮挡
  • 自定义滚动参数，让列表具有不同的滚动反馈和惯性

简单用例

1.默认构造器

  • child作用域内，所有滚动组件会公用一个physics。如果有滚动嵌套，请使用EasyRefresh.builder或用ScrollConfiguration设置作用域
  EasyRefresh(
    onRefresh: () async {
      ....
    },
    onLoad: () async {
      ....
    },
    child: ListView(),
  )

2.builder构造器

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

3.指示器定位

  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.控制器使用

  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.使用指定的 Header 和 Footer

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