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 (_direction.value == null) {
    return super.toString();
  }

  final direction = _direction.value == null
      ? ''
      : ' to ${_direction.cardinal} ($_direction)';

  return '${super.toString()}$direction';
}
