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 code = this.code;
  return [
    '$_typeName(',
    [
      message,
      if (code != null) 'code: ${code is Enum ? code.name : code}',
    ].join(', '),
    ')'
  ].join();
}
