If you need specific Cupertino elements, such as dragging to close, you can use GetCupertino:
```dart
class Router {
static Route<dynamic> generateRoute(RouteSettings settings) {
switch (settings.name) {
case '/':
return GetCupertino(
page: First(),
settings: settings,

case '/second':
return GetCupertino(

default:
return GetCupertino(
settings: settings,
page: Scaffold(
body:
Center(child: Text('No route defined for ${settings.name}')),
));
}
}
}
```
