Add new params to add RouteSettings to Navigator

[tegkev]

The default MaterialPageRoute take settings (RouteSettings) as param, is neccesary to add a route in the Navigator. But we can' t pass the settings as param to the constructor PageTransition

Alternatively, extract the arguments using onGenerateRoute;

Instead of extracting the arguments directly inside the widget, you can also extract the arguments inside an onGenerateRoute() function and pass them to a widget.

onGenerateRoute: (settings) {
    switch (settings.name) {
      case '/second':
        return PageTransition(child: SecondPage(), type: PageTransitionType.scale);
        break;
      default:
        return null;
    }
  },
