    if (event.type == KeyType.left) {
      widget.value = (widget.value - step).clamp(widget.min, widget.max);
      widget.onChanged?.call(widget.value);
      return true;
    } else if (event.type == KeyType.right) {
      widget.value = (widget.value + step).clamp(widget.min, widget.max);
      widget.onChanged?.call(widget.value);
      return true;
    }
  } else {
    if (event.type == KeyType.up) {
      widget.value = (widget.value + step).clamp(widget.min, widget.max);
      widget.onChanged?.call(widget.value);
      return true;
    } else if (event.type == KeyType.down) {
