Routing is not working as expected in flutter

In a Flutter app I have the following code in main.dart

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(),
      initialRoute: '/login',
      onGenerateRoute: Router.generateRoute,
    );

My Router.dart has the below code

class Router {
  static Route<dynamic> generateRoute(RouteSettings settings) {
    print('setting.name: ${settings.name}');
    switch (settings.name) {
      case '/':
        return MaterialPageRoute(builder: (_) => HomeView());
      case '/login':
        return MaterialPageRoute(builder: (_) => LoginView());
      case '/post':
        return MaterialPageRoute(builder: (_) => PostView());
      default:
        return MaterialPageRoute(
          builder: (_) {
            return Scaffold(
              body: Center(
                child: Text('No Route for ${settings.name}'),
              ),
            );
          },
        );
    }
  }
}

and my home_view.dart has the below code

class HomeView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    print('homeview');
    return Scaffold();
  }

I am printing the value of settings.name in router.dart. When I start the app I get the below output in debug console:

Launching lib\main.dart on Android SDK built for x86 in debug mode...

I/flutter (13000): setting.name: /
I/flutter (13000): setting.name: /login
I/flutter (13000): homeview

Since initialRoute is set to '/login', I am not sure why am I getting

I/flutter (13000): setting.name: / and 
I/flutter (13000): homeview

I expected it to directly go to '/login' case and render LoginView. Can someone explain what's happening here?
