DateRules class abstract final

Factory class for creating DateTime validation rules.

All rules are generic over the error type E, so you can use String, enum, sealed classes, or any custom error type.

Example

final birthDateValidator = Validate.all<DateTime, String>([
  DateRules.past(error: 'Birth date must be in the past'),
  DateRules.age(18, 120, error: 'Must be 18-120 years old'),
]);
