# KeyboardEvent constructor

KeyboardEvent(String type, { Window view, bool canBubble: true, bool cancelable: true, int location, int keyLocation, bool ctrlKey: false, bool altKey: false, bool shiftKey: false, bool metaKey: false })

Programmatically create a KeyboardEvent.

Due to browser differences, keyCode, charCode, or keyIdentifier values cannot be specified in this base level constructor. This constructor enables the user to programmatically create and dispatch a KeyboardEvent, but it will not contain any particular key content. For programmatically creating keyboard events with specific key value contents, see the custom Event KeyEvent.

## Implementation

    factory KeyboardEvent(String type,
        {Window view,
        bool canBubble: true,
        bool cancelable: true,
        int location,
        int keyLocation, // Legacy alias for location
        bool ctrlKey: false,
        bool altKey: false,
        bool shiftKey: false,
        bool metaKey: false}) {
      if (view == null) {
        view = window;
      }
      location ??= keyLocation ?? 1;
      KeyboardEvent e = document._createEvent("KeyboardEvent");
      e._initKeyboardEvent(type, canBubble, cancelable, view, "", location,
          ctrlKey, altKey, shiftKey, metaKey);
      return e;
    }
