BlocxFieldValidator<T> class abstract

Base class for field validators used in form validation.

Subclasses should implement validate to provide custom validation logic for a specific field type T. The validate method returns a list of error messages for the given value. An empty list indicates the value is valid.

The optional duration getter can be overridden to specify a duration for timed errors when used with TimedErrorMessage.

Example usage:

class NonEmptyValidator extends BlocxFieldValidator<String> {
  @override
  List<String> validate(String value) {
    return value.isEmpty ? ['Field cannot be empty'] : [];
  }

  @override
  Duration get duration => Duration(seconds: 3);
}
