For example. This import. The NavController. Not usable, but it’s available in the Ionic 4 framework. Why?

import { NavController } from '@ionic/angular';

Also here some docs about the ion-nav element. I guess it’s the replacement for ion-navbar. And navPop on a button in the header to close modals.

I wondering why using ion-nav because the official docs explains using ion-toolbar for it. See https://ionicframework.com/docs/api/header

Please, can someone enlighten me?
