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(),
)))
)
然后在我的HomePage
我有一个推动新路线的FAB。这条新路线无法访问我继承的小部件的上下文。
是否不可能获得InheritedWidget
新路线的上下文,或者有没有办法解决这个问题?
更新
这是我的 MaterialApp 的 builder 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
我的有关HomePage
