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
toString(){
  switch(this){

    case NameValidationMode.none:
      return "None";
    case NameValidationMode.contain:
      return "Contain";
    case NameValidationMode.exact:
      return "Match";
  }
}
