toString method

  1. @override
String toString()
override

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 contents = [
    if (valueInt != null) 'valueInt=$valueInt',
    if (valueFloat != null) 'valueFloat=$valueFloat',
    if (valueDouble != null) 'valueDouble=$valueDouble',
    'namespace=$namespace',
    'op=$op',
  ].join(',');
  return 'NumericRestriction($contents)';
}
