title: Ionic Navigator Launch doesn't work. I click on button and nothing happens
body: <p>I'm struggling to develop a card that, when clicked, open any Maps app from the device, mainly using this tutorial: <a href="https://www.youtube.com/watch?v=BHBLjRuzb7s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=BHBLjRuzb7s</a></p>
  
  <p>Although I coded the same code it's not working since nothing happens when I click the button.</p>
  
  <p>This is my html file:</p>
  
  <pre><code>&lt;div&gt;
    &lt;ion-card&gt;
      &lt;div&gt;
        &lt;img src="{{UnitLocal}}"&gt;
      &lt;/div&gt;
      &lt;ion-item&gt;
        &lt;button ion-button block (click)="navToMaps()"&gt;Universidade Tiradentes&lt;/button&gt;
      &lt;/ion-item&gt;
    &lt;/ion-card&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And this is my ts file:</p>
  
  <pre><code>import { Component } from '@angular/core';
  
  import { LaunchNavigator, LaunchNavigatorOptions } from '@ionic-native/launch-navigator/ngx';
  
  @Component({
    selector: 'unitmap',
    templateUrl: 'unitmap.html'
  })
  export class UnitmapComponent {
    private UnitLocal: string;
    private UnitEndereco: string;
  
    constructor(private launchNavigator: LaunchNavigator) {
      this.UnitLocal = this.getMap();
      this.UnitEndereco = "Universidade Tiradentes, Aracaju";
    }
  
    navToMaps() {
      console.log('Navegando para mapas');
      this.launchNavigator.navigate(this.UnitEndereco);
    }
  }
  </code></pre>
  
  <p>When I run the app through the browser I'm able to get the console log, so I'm assuming the button references navToMaps correctly.</p>
