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 leading = '';
  if (from != null) {
    leading = '($argument)';
  }

  var trailing = '';
  if (name != null) {
    trailing = '$name:';
  }

  return '$trailing${describeIdentity(this)}$leading';
}
