自定义路由后启动时出现黑屏

Question

据我所知，我为Flutter应用编写了以下路由逻辑。而且，我从著名开发者Filled Stacks教程中复制了它。

class Router {
  static Route<dynamic> generateRoute(RouteSettings settings) {
    switch (settings.name) {
      case '/':
        return MaterialPageRoute(builder: (_) => HomeView());
      case 'compartment':
        int compartmentId = settings.arguments as int;
        return MaterialPageRoute(
            builder: (_) => CompartmentView(id: compartmentId));
      case 'newCompartment':
        return MaterialPageRoute(
            builder: (_) => EditCompartmentView(isEditing: false));
      case 'editCompartment':
        var compartment = settings.arguments as Compartment;
        return MaterialPageRoute(
            builder: (_) =>
                EditCompartmentView(compartment: compartment, isEditing: true));
      default:
        return MaterialPageRoute(builder: (_) {
          return Scaffold(
            body: Center(
              child: Text('No existe una ruta definida para ${settings.name}'),
            ),
          );
        });
    }
  }
}

从入口点开始，我正在按以下方式使用它：

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Permafrost',
      theme: ThemeData(
        primarySwatch: Colors.indigo,
      ),
      initialRoute: '/',
      onGenerateRoute: Router.generateRoute,
    );
  }
}

由于某种原因，每当我启动该应用程序时，屏幕都是黑色的。控制台中没有错误消息。热重新加载应用程序后，一切似乎都按预期工作。我有什么不考虑的吗？
