flutter - Why popuntil on generateRoute make my application blank

Question

I have generateRoute.

class Routes {
  static Route<dynamic> generateRoute(RouteSettings settings) {
    switch (settings.name) {
      case homeRoute:
        return MaterialPageRoute(
          builder: (_) => HomePage(),
        );
      case createInquiryRoute:
        return MaterialPageRoute(
          builder: (_) => CreateInquiryPage(),
        );
      default:
        return MaterialPageRoute(
          builder: (_) => Scaffold(
            body: Center(
              child: Text(
                'No route defined for ${settings.name}',
              ),
            ),
          ),
        );
    }
  }
}

I am on homeRoute and push into createInquiryRoute using:

Navigator.of(context).pushNamed(constant.createInquiryRoute);

In my createInquiryRoute, i have a dialog and a button inside it. I want to back to homeRoute when the dialog in createInquiryRoute is show by click the button inside the dialog.

I tried:

Navigator.of(context).popUntil(ModalRoute.withName(constant.homeRoute));

But it sends me into a blank page.

But, when I am not using generateRoute, suppose I am using routes and do the same way to close the dialog and back to prev page, my applicaation works. Why?

*I am using generateRoute because sometime I pass params to other screen.
