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 contact = '<';

  if (anonymous) {
    contact += temp_gruu ?? 'sip:[e-mail];transport=ws';
  } else {
    contact += pub_gruu ?? uri.toString();
  }

  if (outbound && (anonymous ? temp_gruu == null : pub_gruu == null)) {
    contact += ';ob';
  }

  contact += '>';
  return contact;
}
