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() {
  final type = T.toString().replaceAll(RegExp(r'\?'), '');
  final id = this.id != null ? "[id='${this.id}']" : "";
  final hashCode = instance != null ? "(${instance.hashCode})" : "";

  return '$type$id$hashCode';
}
