BorderRadius? normalizeBorderRadius(BorderRadius? borderRadius, double width)

Decreases borderRadius to <= width / 2

Implementation

BorderRadius? normalizeBorderRadius(
  BorderRadius? borderRadius,
  double width,
) {
  if (borderRadius == null) {
    return null;
  }

  }

  Radius topRight;
  if (borderRadius.topRight.x > width / 2 ||
      borderRadius.topRight.y > width / 2) {
    topRight = Radius.circular(width / 2);
  } else {
    topRight = borderRadius.topRight;
  }

  Radius bottomLeft;

      borderRadius.bottomLeft.y > width / 2) {
