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() {
  return [
    [type, if (code != null) '($code)'].join(),
    [message, if (details?.isNotEmpty == true) details].join(' - '),
  ].join(': ');
}
