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 String positions = container
      .map(
        (SimpleContainer e) => e.toString(),
      )
      .join(",")
      .replaceAll(RegExp("[go()]"), "");
  if (added) {
    return "mirror()";
  }

  return "mirror({$positions},$direction)";
}
