我可以使用提供程序包装MaterialApp小部件吗?

问题描述

我是扑朔迷离的新手，我正在尝试使用提供程序创建一个应用程序.我用ChangeNotifierProvider包装了MaterialApp小部件，并且该应用程序可以运行，并且可以按预期使用提供程序.我需要知道是否可以这样做，我会遇到任何问题吗?

I'm new to flutter and I'm trying to create an app with provider. I wrapped MaterialApp widget with the ChangeNotifierProvider and the app works and I can use the provider as it intended to do. I need to know is it okay to do so and will i face any problems?

Widget build(BuildContext context) {
    return ChangeNotifierProvider<BaseModel>(
        builder: (context) =>
            BaseModel(loading: false, title: "Title", isLoggedIn: false),
        child: MaterialApp(
            routes: <String, WidgetBuilder>{
                "/home": (BuildContext context) => Home(),
                "/signIn": (BuildContext context) => SignIn()
            },
            initialRoute: "/signIn",
            title: 'Flutter Demo',
            theme: ThemeData(
                // is not restarted.
                primarySwatch: Colors.blue,
            ),
            home: SignIn()),
    );

在所有示例代码中，他们在MaterialApp小部件的主页"下使用Provider.我在提供程序内部使用了MaterialApp.

In all the sample codes they use Provider under "home" in MaterialApp widget. I used MaterialApp inside the provider.
