How to check which subclass is the event fired?

Issue

I know event.type in DOM. I can parse for example mouseup, keydown, touchstart and so on. But how can I check for the event subclass? Like MouseEvent, AnimationEvent or ClipboardEvent? Can I use the event.type property?

Solution

You can check the class like

void myHandler(Event e) {
  if(e is MouseEvent) {
    print('Mouse');
  } else if(e is AnimationEvent) {
    print('Animation');
  } else if(e is KeyboardEvent) {
    print('Keyboard');
  }
}
