【问题描述】：
我有一个问题，我有一个主要活动，到目前为止我已经加载了几个小部件类。 现在我要做的是在关闭抽屉菜单中触发的页面后刷新主页。
如果按钮直接在主页上，它可以工作，但如果操作是从抽屉菜单触发的，则它不起作用。
选项 2 它应该看起来像这样。但是当我从抽屉菜单调用页面时它不起作用
参考链接： How to go back and refresh the previous page in Flutter? How to refresh a page after back button pressed
有没有人有想法。 以下是选项 1 与主页上的按钮一起使用的代码：
new RaisedButton(
onPressed: ()=>
Navigator.of(context).push(new MaterialPageRoute(builder: (_)=>new PageHomeContent()),)
.then((val)=>{getRefreshRequests()}),
child: Text('Refresh', style: TextStyle(color: Colors.white), ), color: Colors.purple,
elevation: 2.0,
),
重要的是要知道我在这里为抽屉菜单创建了一个类。它有点长，但我很重要
