翩翩从安卓抽屉菜单中打开页面后如何刷新主页面？

Posted 2023-01-29

我有一个问题，我有一个主活动，在那里我已经加载了几个widget类，到目前为止还不错。现在我想做的是在关闭一个在抽屉菜单中触发的页面后刷新主页面。

如果按钮直接在主页面上，它可以工作，但如果动作是从抽屉菜单中触发的，它不能工作。

画面示例或者说它的效果非常好

选项2它应该是这样的，但当我从抽屉菜单中调用页面时，它就不工作了。

有谁有一个想法.这里是代码，用于选项1与主页面上的按钮。

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，我已经为抽屉菜单创建了一个类，它有点长，但我你必须要知道。

final Color primaryColor = Colors.white;
final Color activeColor = Colors.grey.shade800;
final Color dividerColor = Colors.grey.shade600;

谁有个建议。

谢谢你的帮助

答案

等待更好的回复。

我替换了 BuildDrawer 阶级与 getBuildDrawer() 方法在主类中。

它的工作原理非常好，但我更希望把它放在一个单独的类中，这样我就可以在另一个页面中使用它......

getBuildDrawer() 
    return ClipPath(
      clipper: OvalRightBorderClipper(),
      child: Drawer(
        child: Container(
          padding: const EdgeInsets.only(left: 16.0, right: 40),
          decoration: BoxDecoration(
              color: primaryColor,
              boxShadow: [BoxShadow(color: Colors.black45)]),
          width: 300,
          child: SafeArea(
            child: SingleChildScrollView(
              child: Column(
                children: <Widget>[
                  Container(
                    padding: const EdgeInsets.symmetric(vertical: 5.0),

                      onTap: () 
                        Navigator.of(context).pop();
      Navigator.of(context).push(new MaterialPageRoute(builder: (_)=>new PageHomeContent()),)
          .then((val)=> getRefreshRequests() );

                        children: <Widget>[
                          Row(
                              children: [

                              ]
                          ),
                        ],
