Ionic package build & hooks

I have a doubt with package service. When I execute this services, my hooks also are included?

I have wrote one hook to minimize my app (js, html, css) but I don’t see difference in the size in the result. I don’t know if the service is executing my hooks.

What do I do for “ionic package” service executes also my hooks?

Thanks and regards.

Doesn’t look like custom hooks are supported yet on their platform
