enforce method

BoxConstraints enforce (BoxConstraints constraints)

Returns new box constraints that respect the given constraints while being as close as possible to the original constraints.

Implementation 

BoxConstraints enforce(BoxConstraints constraints) {
  return BoxConstraints(
    minWidth: minWidth.clamp(constraints.minWidth, constraints.maxWidth),
    maxWidth: maxWidth.clamp(constraints.minWidth, constraints.maxWidth),
    minHeight: minHeight.clamp(constraints.minHeight, constraints.maxHeight),
    maxHeight: maxHeight.clamp(constraints.minHeight, constraints.maxHeight)
  );
}
