intersect method

Rect intersect (Rect other)

Returns a new rectangle that is the intersection of the given rectangle and this rectangle. The two rectangles must overlap for this to be meaningful. If the two rectangles do not overlap, then the resulting Rect will have a negative width or height.

Implementation

Rect intersect(Rect other) {
  return new Rect.fromLTRB(
    math.max(left, other.left),
    math.max(top, other.top),
    math.min(right, other.right),
    math.min(bottom, other.bottom)
  );
}
