toString method

@override String toString({ String? message, })

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({String? message}) {
  message ??= message;
  return '$classCode.$subjectCode.$detailCode'
      '${message == null ? '' : ' $message'}';
}
