toString method

  1. @override
String toString()
inherited

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 content = {
    'name': name,
    'from': from,
    'argument': argument,
  }.entries.where((e) => e.value != null).map((e) => '${e.key}: ${e.value}');

  return '${describeIdentity(this)}$content';
}
