# UIEvent constructor Null safety

UIEvent(

1. String type,
2. {Window? view,
3. int detail: 0,
4. bool canBubble: true,
5. bool cancelable: true}

)

## Implementation

    factory UIEvent(String type,
        {Window? view,
        int detail: 0,
        bool canBubble: true,
        bool cancelable: true}) {
      if (view == null) {
        view = window;
      }
      UIEvent e = document._createEvent("UIEvent") as UIEvent;
      e._initUIEvent(type, canBubble, cancelable, view, detail);
      return e;
    }
