Validating a number has a maximum value

import 'package:luthor/luthor.dart';

void main() {
  final intValidator = l.int().max(42);
  final doubleValidator = l.double().max(42.0);
  final numberValidator = l.number().max(42);

  print(intValidator.validateValue(42));
  print(doubleValidator.validateValue(42.0));
  print(numberValidator.validateValue(42));
}

You can use the @HasMax, @HasMaxDouble, and @HasMaxNumber annotations to validate that a number has a maximum value. @HasMax is used for int, @HasMaxDouble is used for double, and @HasMaxNumber is used for num.
