Gesture Controller

Im trying to get the gesture controller demo to work. Any ideas what im missing?

Im getting this error. Also the code is under the tab1 folder.

 ERROR Error: Uncaught (in promise): TypeError: Cannot read property '__zone_symbol__addEventListener' of undefined```

Ok figured it out. I needed to define my viewchild differently.


  @ViewChild('rectangle', { static: true, read: ElementRef }) rectangle: ElementRef;


  @ViewChild('rectangle') rectangle: ElementRef;

Great catch! Good to know what goes wrong and why they introduced this change - I am still a bit thinking Angular < v8… Thx for sharing your learning.
