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控件。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。

在布局文件中添加 EasyreFresh

import 'package:flutter_easyrefresh/easy_refresh.dart';
//....
// 方式一
EasyRefresh(
  child: ScrollView(),
  onRefresh: () async{
    ....
    },
  onLoad: () async {
    ....
    },
)
  // 方式二
  EasyRefresh.custom(
  slivers: <Widget>[],
  onRefresh: () async{
    ....
    },
  onLoad: () async {
    ....
    },
)
  // 方式三
  EasyRefresh.builder(
  builder: (context, physics, header, footer) {
    return CustomScrollView(
      physics: physics,
      slivers: <Widget>[
        ...
        header,
        ...
        footer,
      ],
    );
  }
  onRefresh: () async{
    ....
    },
  onLoad: () async {
    ....
    },
)

触发刷新和加载动作

EasyRefreshController _controller = EasyRefreshController();
  ....
  EasyRefresh(
    controller: _controller,
    ....
  );
  ....
  _controller.callRefresh();
  _controller.callLoad();

控制加载和刷新完成

EasyRefreshController _controller = EasyRefreshController();
  ....
  EasyRefresh(
 enableControlFinishRefresh: true,
 enableControlFinishLoad: true,
    ....
  );
  ....
  _controller.finishRefresh(success: true);
  _controller.finishLoad(success： true, noMore: false);

使用指定的 Header 和 Footer

import 'package:flutter_easyrefresh/easy_refresh.dart';
import 'package:flutter_easyrefresh/material_header.dart';
import 'package:flutter_easyrefresh/material_footer.dart';
....
  new EasyRefresh(
    header: MaterialHeader(),
    footer: MaterialFooter(),
    child: ScrollView(),
    ....
  )

添加国际化支持

不提供自带国际化支持，请自行设置ClassicalHeader和ClassicalFooter中需要展示的文字。

ClassicalHeader API

EasyRefresh(
    header: ClassicalHeader(
      double extent = 60.0,
    double triggerDistance = 70.0,
    bool float = false,    //Header 浮动（Header显示在列表之上）
    Duration completeDuration = const Duration(seconds: 1),
    bool enableInfiniteRefresh = false,    //是否开启无限加载
    bool enableHapticFeedback = true,    //是否触发震动反馈
    bool overScroll = true,
    this.key,
    this.alignment,    //对齐
    this.refreshText,    //提示刷新文字(下拉刷新)
    this.refreshReadyText,    //准备刷新文字(释放刷新)
    this.refreshingText,    //正在刷新文字(刷新中)
    this.refreshedText,    //刷新完成文字(刷新完成)
    this.refreshFailedText,    //刷新失败文字
    this.noMoreText,    //没有更多文字
    this.showInfo: true,    //是否显示额外信息(默认为时间)
    this.infoText,    //额外信息
    this.bgColor: Colors.transparent,    //背景颜色
    this.textColor: Colors.black,    //字体颜色
    this.infoColor: Colors.teal,    //额外信息字体颜色
  ),
),

ClassicalFooter API

footer:   ClassicalFooter({
  double extent = 60.0,
  double triggerDistance = 70.0,
  bool float = false,
  Duration completeDuration = const Duration(seconds: 1),
  bool enableInfiniteLoad = true,    //是否开启无限加载
  bool enableHapticFeedback = true,    //是否触发震动反馈
  bool overScroll = false,    //上拉到底部时，是否继续允许往上拖拽页面（是否允许超出滚动区域）
  bool safeArea = true,
  EdgeInsets padding,
  this.key,
  this.alignment,
  this.loadText,    //提示加载文字
  this.loadReadyText,    // 准备加载文字
  this.loadingText,    // 正在加载文字
  this.loadedText,    // 加载完成文字
  this.loadFailedText,    // 加载失败文字
  this.noMoreText,
  this.showInfo: true,
  this.infoText,
  this.bgColor: Colors.transparent,
  this.textColor: Colors.black,
  this.infoColor: Colors.teal,
})

构造器API

控制器

import 'package:flutter_easyrefresh/easy_refresh.dart';
EasyRefreshController _controller;
initState(){
  _controller = EasyRefreshController();
}
_controller.callRefresh();    //触发刷新
callLoad();    // 触发加载
finishRefresh();    // 完成刷新
finishLoad();    // 完成加载
resetRefreshState();    // 恢复刷新状态(用于没有更多后)
resetLoadState();    // 恢复加载状态(用于没有更多后)
_controller._easyRefreshState;    // 状态

默认构造器

/// 默认构造器
/// 将child转换为CustomScrollView可用的slivers
EasyRefresh({
  Key key,
  this.controller,    // 控制器
  this.scrollController,
  this.onRefresh,    //刷新回调(null为不开启刷新)
  this.onLoad,    // 加载回调(null为不开启加载)
  this.enableControlFinishRefresh = false,    // 是否开启控制结束刷新
  this.enableControlFinishLoad = false,    // 是否开启控制结束加载
  this.taskIndependence = false,    // 任务独立(刷新和加载状态独立)
  this.header,
  this.headerIndex,
  this.footer,
  this.firstRefresh,    // 首次刷新
  this.firstRefreshWidget,    // 首次刷新组件,不设置时使用header
  this.emptyWidget,    // 空视图,当不为null时,只会显示空视图,保留[headerIndex]以上的内容
  this.topBouncing = true,    // 顶部回弹(Header的overScroll属性优先，且onRefresh和header都为null时生效)
  this.bottomBouncing = true,    // 底部回弹(Footer的overScroll属性优先，且onLoad和footer都为null时生效)
  this.behavior = const EmptyOverScrollScrollBehavior(),    // 滚动行为
  @required this.child,
})

custom 构造器

/// 直接使用CustomScrollView可用的slivers
EasyRefresh.custom({
  ...
    this.listKey,
  this.scrollDirection = Axis.vertical,    // 列表方向
  this.reverse = false,    // 反向
  this.scrollController,
  this.primary,
  this.shrinkWrap = false,
  this.center,
  this.anchor = 0.0,
  this.cacheExtent,
  this.semanticChildCount,
  this.dragStartBehavior = DragStartBehavior.start,
  @required this.slivers,
})

EasyRefresh.builder

EasyRefresh.builder({
  Key key,
  this.controller,
  this.onRefresh,
  this.onLoad,
  this.enableControlFinishRefresh = false,
  this.enableControlFinishLoad = false,
  this.taskIndependence = false,
  this.scrollController,
  this.header,
  this.footer,
  this.firstRefresh,
  this.topBouncing = true,
  this.bottomBouncing = true,
  this.behavior = const EmptyOverScrollScrollBehavior(),
  @required this.builder,    // 子组件构造器(final EasyRefreshChildBuilder builder;)
})

EasyRefreshChildBuilder 构造函数

typedef EasyRefreshChildBuilder = Widget Function(
    BuildContext context, ScrollPhysics physics, Widget header, Widget footer);

ScrollNotificationInterceptor() 滚动通知拦截器

滚动通知拦截器(用于拦截其他UI组件的滑动事件)。

经试验，不用该组件包裹，好像也没啥问题。

  @override
  _SwiperRefreshState createState() => _SwiperRefreshState();
}
class _SwiperRefreshState extends State<SwiperRefresh> {
  int _count = 20; // 条目总数
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: EasyRefresh.builder(
        builder: (context, physics, header, footer) {
          return CustomScrollView(
            slivers: [
              SliverList(
                delegate: SliverChildListDelegate([
                  Container(
                    height: 210,
                    // 滚动通知拦截器(用于拦截其他UI组件的滑动事件)
                    child: ScrollNotificationInterceptor(
                      child: Swiper(
                        itemCount: 5,
                        viewportFraction: 0.8,
                        scale: 0.9,
                        itemBuilder: (context, index) {
                          return Container(
                            height: double.infinity,
                            color: Color(Base.getRandomColor()),
                            child: Center(child: Text('swiper ${index + 1}', textScaleFactor: 2)),
                          );
                        },
                      ),
                    ),
                  ),
                ]),
              ),
            ],
          );
        },
      ),
    );
  }
}
