@override
bool handle(Map<String, dynamic> info) {
  RegExp regExp = RegExp("max:([0-9]+)");
  String match = regExp.firstMatch(info['rule'])!.group(1) ?? "";
  int intMatch = int.parse(match);
  this.description =
      "The $attribute must have a maximum length of $intMatch characters.";
  super.handle(info);

  return (info['data'].toString().length < intMatch);
}
