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() {
  final s = state != null ? ', $state' : '';
  final z = zipCode != null ? ', $zipCode' : '';
  return 'Type: $identifier\nPreferred: $preferred\n$street, $city$s$z, $country';
}
