title: Ionic 5 - Angular listen to pinch gesture
body: <p>I am updating an Ionic 3 application to Ionic 5. In my app I use</p>
  <pre><code>         this.gesture = new Gesture(this.myElement.nativeElement);
       
           this.gesture.listen();
     
           this.gesture.on('pinchend', pinchEvent =&gt; {
             const scale = pinchEvent.scale;
             ......
  
           });
  </code></pre>
  <p>this ultimately to control the zoom of the camera.</p>
  <p>In Ionic 5 the angular Gesture is not an option anymore so I tried to use the new Gesture  Controller following the official docs but I cannot get the data I need (scale of the pinch), I think it does not support 2 fingers gesture.</p>
  <p>How can I listen to the pinch gesture in Ionic 5 and get information on the scale of the pinch event?</p>
