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() {
  String error = "";
  error = message == null ? error : "message :$message \n";
  error = description == null ? error : "$error description :$description \n";
  error = resource == null ? error : "$error resource :$resource \n";
  error = errors == null ? error : "$error ${errors.toString()}";
  return error;
}
