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 retval = "";
  if (route != null) {
    retval = "Route: $route\n";
  }
  retval += message + (submessage ?? "") +
    "\n${reasonToString(reason??Reason.confirm)}";
  return retval;

}
