Error "tried calling SplashScreen.hide, but the SplashScreen plugin is not installed"

I know this is off-topic, but just to answer to your question.
If I have this code:

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html'
})
export class AppComponent {

	...
	myTestClassVariable: number;

  constructor(
    private platform: Platform,
	.....
  ) {
    this.initializeApp();
    this.myTestClassVariable = 5;
  }

  initializeApp() {
    const context = this;
    context.settings.initAppSettings();
    context.platform.ready().then(() => {
      console.log(this.myTestClassVariable);
      debugger;
	  ...
	  }
  }
}

When Chrome stops at the breakpoint I have this situation:
