_getRight() is wrong!

double? _getRight() {
    if (_isRight()) {
      var rightPadding =
          widget.position!.getCenter() + (_getTooltipWidth() / 2);
      if (rightPadding + _getTooltipWidth() > widget.screenSize!.width) {
        rightPadding = 14;
      }
      return rightPadding;
    } else if (!(_isLeft())) {
      return widget.position!.getCenter() - (_getTooltipWidth() * 0.5);
    } else {
      return null;
    }
  }

should be

  double? _getRight() {
    if (_isRight()) {
      var rightPadding =
          widget.position!.getCenter() + (_getTooltipWidth() / 2);
      if (rightPadding + _getTooltipWidth() > widget.screenSize!.width) {
        rightPadding = 14;
      }
      return rightPadding;
    } else if (!(_isLeft())) {
      return widget.screenSize!.width - widget.position!.getCenter() - (_getTooltipWidth() * 0.5);
    } else {
      return null;
    }
  }

The result

Please fix this

Why use _getTooltipWidth() caculate so many times? The code is so ineffective.
