BlocxSingleErrorFieldValidator<T> class abstract

A base class for field validators that produce at most a single error message.

This class is intended for simple validation scenarios where each field can only produce one error. It wraps the result of validateWithSingleError into a list so it is compatible with the multi-error API of BlocxFieldValidator.

Subclasses must implement validateWithSingleError to define the actual validation logic. Subclasses should NOT override validate, as it is internally used to convert a single error into a list of errors.
