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 String detail = <String>[
    if (statusCode != null) 'HTTP $statusCode',
    ?code,
  ].join(' ');
  return detail.isEmpty
      ? '$runtimeType: $message'
      : '$runtimeType($detail): $message';
}
