Having trouble importing ViewController into Provider in Ionic 2?

Struggling to figure out how to import my view controller for usage in a provider within Ionic 2.

import { ModalController, ViewController, NavController } from "ionic-angular";

@Injectable()
export class DynamicModal<T extends IHasId> {

    modalOptions: DynamicModalOptions<T>;

    constructor(public modalCtrl: ModalController, public viewCtrl: ViewController)

Attempting it this way triggers the following error message:

No provider for ViewController

While View Controllers work seamlessly when injected into pages, I am looking to centralize creation and dismissal logic to avoid duplicating it every time I use that modal.

Any suggestions on how to inject a view controller into a modal?

Answer №1

To avoid injecting the view controller, you can add it to your modal options:

export class DynamicModalOptions<T extends IHasId>
{
    entity: T;
    //other properties
    viewCtrl: ViewController;
}

When dismissing, simply access the view controller from your options:

close() {
    this.modalOptions.viewCtrl.dismiss();
    this.modalOptions = null;
}

Remember to clear your modal options in your provider to prevent them from being injected again next time.

Answer №2

There is no requirement to declare it within the app.module.ts file; you simply need to import and declare it in the class constructor:

import { ViewController } from "ionic-native";

export class DynamicModal<T extends IHasId> {
  constructor(private viewCtrl: ViewController) {}
}
