In Angular9 ViewChild requires to specify {static: boolean}.

I think it can be fixed(maybe not completely) by adding {static: true} to below lines. https://github.com/dockleryxk/ng-simple-slideshow/blob/f563ac58b8c20e27caeaa0be9b2258560604b99a/src/app/modules/slideshow/slideshow.component.ts#L66

  @ViewChild('container', { static: true }) container: ElementRef;
  @ViewChild('prevArrow', { static: true }) prevArrow: ElementRef;
  @ViewChild('nextArrow', { static: true }) nextArrow: ElementRef;
