flutter - The builder for route "/" returned null

Question

I defined a non null route for '/', but I still get an error :/ If I provide a home parameter to MaterialApp, it will work fine.

return MaterialApp(
    debugShowCheckedModeBanner: false,
    title: 'My App',
    theme: AppTheme.lightMode,
    darkTheme: AppTheme.darkMode,
    themeMode: themeChanger.getTheme,
    initialRoute: '/',
    routes: {
      '/': (ctx) => LoginPage(),
      '/home': (ctx) => homePage,
      CoursesPage.routeName: (ctx) => CoursesPage(),
      CourseDetailsPage.routeName: (ctx) =>
          CourseDetailsPage(),
      CourseInside.routeName: (ctx) => CourseInside()
    },
  );
