clipRRect method

void clipRRect (RRect rrect, { bool doAntiAlias: true })

Reduces the clip region to the intersection of the current clip and the given rounded rectangle.

If doAntiAlias is true, then the clip will be anti-aliased.

If multiple draw commands intersect with the clip boundary, this can result in incorrect blending at the clip boundary. See saveLayer for a discussion of how to address that and some examples of using clipRRect.

Implementation 

void clipRRect(RRect rrect, {bool doAntiAlias = true}) {
  assert(_rrectIsValid(rrect));
  assert(doAntiAlias != null);
  _clipRRect(rrect._value, doAntiAlias);
}
