Short description of the problem:

My app works fine when using ionic serve. However, when I run a build (e.g. ionic run android), ngc will throw an error:

[21:56:25]  ngc: Error: Error at D:/Users/User/Desktop/project/.tmp/app/app.module.ngfactory.ts:587:140: Property 'string' does not exist on type 'typeof "D:/Users/User/Desktop/project/.tmp/providers/firebase.service"'.

The constructor code in question is below:

Injectable()
export class FirebaseService extends AngularFire {
...
    constructor(firebaseConfig: string, auth: AngularFireAuth, database: AngularFireDatabase) {
        super(firebaseConfig, auth, database)
    }
...
}

Some people on the forum have worked around this by removing all mention of string in the constructor, but because I am extending from the AngularFire class, I must state the super call as is.

What behavior are you expecting?

ngc should not throw an error(?)

Steps to reproduce:

  1. Create a class with a string variable in the constructor.
  2. Include said class in app.module.ts
  3. Run $ npm run build or $ ionic run android or $ ionic run ios

Which @ionic/app-scripts version are you using?
0.0.30
