BREAKING CHANGES:
- Overlay components, such as Alert or Modals, should now be created
using its injected provider.
- Overlays now have the `present()` method on the overlay’s instance,
rather than using `nav.present(overlayInstance)`.
- All overlays now present on top of all app content, to include menus.
- Below is an example of the change to `Alert`, but the pattern is the
same for all overlays: ActionSheet, Loading, Modal, Picker, Popover,
Toast
WAS:
```
import { NavController, Alert } from ‘ionic-angular’;
constructor(private nav: NavController) {
}
doAlert() {
let alert = Alert.create({
title: 'Alert',
});
this.nav.present(alert);
}
```
NOW:
```
import { AlertController } from ‘ionic-angular’;
constructor(private alertCtrl: AlertController) {
}
doAlert() {
let alert = this.alertCtrl.create({
title: 'Alert'
});
alert.present();
}
```
