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 buffer = StringBuffer();

  if (min == max) {
    buffer.write(min);
  } else {
    buffer.write(min > 0 ? '$min*' : '*');

    if (max != null) {
      buffer.write(max!);
    }
  }

  buffer.write('(${element is Rule ? (element as Rule).name : element})');
  return buffer.toString();
}
