isNormalized property

bool isNormalized

Returns whether the object's constraints are normalized. Constraints are normalized if the minimums are less than or equal to the corresponding maximums.

For example, a BoxConstraints object with a minWidth of 100.0 and a maxWidth of 90.0 is not normalized.

Most of the APIs on BoxConstraints expect the constraints to be normalized and have undefined behavior when they are not. In checked mode, many of these APIs will assert if the constraints are not normalized.


bool get isNormalized {
  return minWidth >= 0.0 &&
         minWidth <= maxWidth &&
         minHeight >= 0.0 &&
         minHeight <= maxHeight;
