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() {
  var message = '$_typeName: ${this.message}\n${classNames.join(' => ')}';
  if (stackTrace != null) {
    message = '$message\n$stackTrace';
  }

  return message;
}
