Ionic 3 Google Maps Integration

I am following this tutorial exactly: https://www.djamware.com/post/58f4da2080aca7414e78a638/step-by-step-tutorial-of-ionic-3-angular-4-and-google-maps-directions-service

But I cannot get it to work. I don't have an API key, but for some reason I keep getting the errorError: Uncaught (in promise): ReferenceError: google is not defined ReferenceError: google is not defined

I am launching the application using ionic lab

For some reason, it doesn't work. Can anyone help me find the problem? I tried adding the whostelist cordova plugin by changing https to http in the key part of the API, but still it doesn't work.

Have you declared a variable at home.ts?



import { Component, ViewChild, ElementRef } from '@angular/core';
import { IonicPage } from 'ionic-angular';
import { NavController } from 'ionic-angular';

declare var google;

@IonicPage()
@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
