Code sample

In pointer_interceptor implementation this;

    (element as web.HTMLElement).style.backgroundColor = 'rgba(255, 0, 0, .5)';
  }

Should be:

  void _onElementCreated(Object element) {
    (element as web.HTMLElement).style.width = '100%';
    (element as web.HTMLElement).style.height = '100%';
    (element as web.HTMLElement).style.backgroundColor = 'rgba(255, 0, 0, .5)';
  }
