How to navigate to the same page from 2 different locations in Flutter Beamer

i have the following pages in my app

• landing
• login
• Registration
• bottom_navigation_page
• contact_us

I'm using beamer 0.14.1 for navigation

the landing page has a 'Contact Us' button that should open the contact_us page, and in the bottom navigation (in the more tab) there is a 'Contact Us' button, currently my beamer navigation looks like this

class StartingLocation extends BeamLocation {
  @override
  List<String> get pathBlueprints => ['/'];

  @override
  List<BeamPage> buildPages(BuildContext context, BeamState state) => [
        BeamPage(
          key: ValueKey('landing'),
          child: LandingPage(),
        ),
      ];
}

class LandingLocation extends BeamLocation {
  @override
  List<String> get pathBlueprints => [
    '/login'
    '/registration'
    '/contactUs',
    ];

  @override
  List<BeamPage> buildPages(BuildContext context, BeamState state) => [
        ...StartingLocation().buildPages(context, state),
        if (state.uri.pathSegments.contains('login'))
          BeamPage(
            key: ValueKey('login'),
            child: LoginPage(),
          ),
        if (state.uri.pathSegments.contains('registration'))
          BeamPage(
            key: ValueKey('registration'),
            child: RegistrationPage(),
          ),
        if (state.uri.pathSegments.contains('contactUs'))
          BeamPage(
            key: ValueKey('contactUs'),
            child: ContactUsPage(),
          ),
      ];
}

class NavigationLocation extends BeamLocation {
  @override
  List<String> get pathBlueprints => [
        '/navigation',
        '/navigation/notifications',
        '/navigation/profile',
    ];

  @override
  List<BeamPage> buildPages(BuildContext context, BeamState state) => [
        ...LandingLocation().buildPages(context, state),
        if (state.uri.pathSegments.contains('navigation'))
          BeamPage(
            key: ValueKey('navigation'),
            child: NavigationPage(),
          ),
        if (state.uri.pathSegments.contains('notifications'))
          BeamPage(
            key: ValueKey('notifications'),
            child: NotificationsPage(),
          ),
        if (state.uri.pathSegments.contains('profile'))
          BeamPage(
            key: ValueKey('profile'),
            child: ProfilePage(),
          ),
      ];
}

in the landing page i use this code to open the contact us page onPressed: () => context.beamToNamed('/contactUs'), and it works fine, but when i use the same code in the more page it throws this error:
