Navigate to other page

I use a Datepicker Cupertiono in my Flutter application:

https://github.com/wuzhendev/flutter-cupertino-date-picker

There is a method named "onConfirm()" where I'm trying to redirect user to other page, but with no luck. I tried 

return        Navigator.pushReplacementNamed(ctx, '/otherPage');

but what actually happens when this return statment is hit, is cupertino widget closes and nothing happen. There is no error

When I try to use :

return Navigator.pushNamed<bool>(
                          ctx,
                          '/route/' + object.id.toString());

Some errors apear:

Performing hot restart...
Restarted application in 1 685ms.

You should use Navigator.push. Import your page, example: import './otherPage.dart';

Than change your line

return Navigator.pushReplacementNamed(ctx, '/otherPage');

To 

return Navigator.push(context, 'otherClassName');
