v3的easy refresh在使用Cupertino样式时，初始化刷新失效

[kidozh]

RT，当我的界面使用了Cupertino的时候，无法初始化刷新，并且有一个很奇怪的placeholder，如下图所示

当然也可以手动下滑刷新出页面，但是每个页面都需要手动下拉刷新，就很麻烦。

但是使用material界面的时候，初始化刷新又是正常的：

这个很迷惑，我也不知道是什么原因。

不清楚你的具体问题是什么，也许参考示例可以帮助你，并找到问题

就是在使用Cupertino样式https://docs.flutter.dev/development/ui/widgets/cupertino下使用EasyRefresh并开启refreshOnStart: true,时，无法在开启的时候自动刷新，而是出现上面的BUG。

我测试没有问题嘞，能给一个简单的示例吗？

请参考这个

import 'dart:io';

import 'package:easy_refresh/easy_refresh.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return const CupertinoApp(
      title: 'Flutter Demo',
      theme: CupertinoThemeData(
          // This is the theme of your application.
          //
          // Try running your application with "flutter run". You'll see the
          // application has a blue toolbar. Then, without quitting the app, try
          // changing the primarySwatch below to Colors.green and then invoke
          // "hot reload" (press "r" in the console where you ran "flutter run",
          // or simply save your changes to "hot reload" in a Flutter IDE).
          // Notice that the counter didn't reset back to zero; the application
          // is not restarted.
          //primarySwatch: Colors.blue,
          ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;
  EasyRefreshController _controller = EasyRefreshController(controlFinishRefresh: true, controlFinishLoad: true);

  @override
  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return CupertinoPageScaffold(
      navigationBar: const CupertinoNavigationBar(
        middle: const Text("DEMO"),
      ),
      child: EasyRefresh(
        header: ClassicHeader(),
        footer: ClassicFooter(),
        refreshOnStart: true,
        controller: _controller,
        onLoad: () async{
          //sleep(Duration(seconds: 5));
          setState((){
            _counter += 10;
          });
          _controller.finishLoad(IndicatorResult.success);
          return IndicatorResult.success;
        },
        onRefresh: () async{
          //sleep(Duration(seconds: 5));
          setState((){
            _counter = 10;
          });

          _controller.finishRefresh(IndicatorResult.success);
          return IndicatorResult.success;

        },
        child: ListView.builder(
          itemBuilder: (context, index) {
            return Card(
              child: Text((index + 1).toString()),
            );
          },
          itemCount: _counter,
        ),
      ),
      // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

这个刚开始就不会刷新界面，界面是这样的

可以隐隐约约看到后台有一个东西在刷新，但是如果用户不自己去下拉刷新，easyrefresh似乎是不会在开始打开界面的时候刷新数据的。

我看了示例代码。这是安全区域的问题，在EasyRefresh外层加一个SafeArea即可。不过首次刷新确实有点问题，没有计算出正确的安全区域偏移量，这个会在下个版本修复

感谢，那我等修复吧，我懒得改了，感谢作者

[xuelongqy]

3.0.4+2应该可以了，不过还是建议你加上SafeArea

好滴，感谢，我去更新一下
