我有以下设置：

MaterialApp(home:SplashScreen)


SplashScreen(
///do some auth checks then
Navigator.of(context).push( MaterialPageRoute(
                builder: (_) =>  StateInheritedWidget(
                  user: userData,
                  child:  HomePage(),

                )))
)

然后在我HomePage的FAB中，我推了一条新路线。这条新路线无法访问我继承的窗口小部件的上下文。

是不可能InheritedWidget在新的路线中获得上下文的，还是有解决此问题的方法？

更新资料

这是我的MaterialApp的构建器属性

    builder: (context,child){
///Doing some auth stuff here
        return new StateInheritedWidget(
          user: userData,
                      child: userData==null?const SplashScreen(child: const LoginPage(),): 
                      const SplashScreen(child: const HomePage(),),

        );
      },

我的SplashScreen构建方法：

return !_load? new Scaffold(
      body: new Center(
        child: new Text('Splash'),
      ),
    ):this.widget.child;

这些是我得到的错误。

第一个似乎与Drawer我的中的有关HomePage：

当我单击FAB（Navigator.push）时出现第二个异常
