Hi,

I need to generate Components with --changeDetection=OnPush. But it is not working.

Error:

$ ionic g component components/client/shipping-service-type --changeDetection=OnPush
> ng.cmd generate component components/client/shipping-service-type --change-detection=OnPush --project=app
Unknown option: '--change-detection'
[ERROR] Could not generate component.
