    return BoxBorderDto(
      top: top?.merge(other.top) ?? other.top,
      bottom: bottom?.merge(other.bottom) ?? other.bottom,
      left: left?.merge(other.left) ?? other.left,
      right: right?.merge(other.right) ?? other.right,
    );
  }

  if (type == BorderDirectional) {
    return BoxBorderDto(
      top: top?.merge(other.top) ?? other.top,
      bottom: bottom?.merge(other.bottom) ?? other.bottom,
      start: start?.merge(other.start) ?? other.start,
      end: end?.merge(other.end) ?? other.end,
