flutter - The builder for route "/" returned null

Question

i literally defined a non null route for '/' but still gettng that error :/ If i give a 'home' paramter 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()
                      },
                    );
