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 messageString = '';
  if (challengeName != null) messageString += ' "$challengeName"';
  if (message != null) messageString += ' $message';
  if (messageString == '') return 'CognitoUserException';
  return 'CognitoUserException:$messageString';
}
