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 result = StringBuffer();
  ResultNode? previous;
  for (ResultNode current in list) {
    if (previous != null) {
      result.write(',');
    }
    result.write(current.toString());
    previous = current;
  }
  return result.toString();
}
