Extensions in Flutter Dart for Static Methods

Question

I created an extension method of the Navigator class as shown below:

extension on Navigator {

  static void navigatorToLoginPage(BuildContext context) {
    Navigator.push(context, MaterialPageRoute(
      builder: (context) => 
      ChangeNotifierProvider(
        create: (context) => LoginViewModel(), 
        child: LoginPage()
      )
    ));
  }

}

Now, I am having problems calling it from another file.

Inside the build function of another widget, I tried calling the Navigator.navigateToLoginPage but it does not recognize the navigateToLoginPage as a static function.

  onTap: () {
                  Navigator.navigateToLoginPage(context); // this is not working. Not recognizing the navigateToLoginPage
                  _navigateToRegisterPage(context);
                }),

Am I missing something?

UPDATE: I was able to achieve it using the following code:

extension AppNavigator on Navigator {

  static void navigateToLoginPage(BuildContext context) {
    Navigator.push(context, MaterialPageRoute(
      builder: (context) => 
      ChangeNotifierProvider(
        create: (context) => LoginViewModel(), 
        child: LoginPage()
      ), fullscreenDialog: true
    ));
  }
}
