toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  if (width == null && height == null) return 'Size.infinite';
  if (width == null) return 'Size.fromHeight($height)';
  if (height == null) return 'Size.fromWidth($width)';

  return 'Size($width, $height)';
}
