toString method

@override String toString()

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() {
  List<String> validOptionNames = [];
  RouteCameraPurpose.values.forEach((element) {
    if (this.contains(element)) {
      validOptionNames.add(element.name);
    }
  });

  return "${this.runtimeType}: ${validOptionNames.join(', ')}";
}
