handleInput method

@override ResponseInput handleInput(InputEvent event)

Handles a generic InputEvent by delegating to tab navigation or mouse processing as appropriate.

• KeyCode.tab → move focus forward
• KeyCode.shiftTab → move focus backward
• MouseEvent → handle hover and clicks

Returns ResponseInput.ignored if the event does not affect focus/hover.

Implementation

@override
ResponseInput handleInput(InputEvent event) {
  if (event is KeyEvent && event.code == KeyCode.shiftTab) {
    return _handleTab(true);
  } else if (event is KeyEvent && event.code == KeyCode.tab) {
    return _handleTab(false);
  } else if (event is MouseEvent) {
    return _handleMouseInput(event);
  }
  return ResponseInput.ignored();
}
