add method

  1. @override
BorderRadiusGeometry add (BorderRadiusGeometry other)
override

Returns the sum of two BorderRadiusGeometry objects.

If you know you are adding two BorderRadius or two BorderRadiusDirectional objects, consider using the + operator instead, which always returns an object of the same type as the operands, and is typed accordingly.

If add is applied to two objects of the same type (BorderRadius or BorderRadiusDirectional), an object of that type will be returned (though this is not reflected in the type system). Otherwise, an object representing a combination of both is returned. That object can be turned into a concrete BorderRadius using resolve.

Implementation 

@override
BorderRadiusGeometry add(BorderRadiusGeometry other) {
  if (other is BorderRadius)
    return this + other;
  return super.add(other);
}
