FormeFieldsValidationListener class

used to listen multi field validation change

eg:

FormeFieldsValidationListener(
      names: const {'password', 'confirm'},
      builder: (context, validation) {
        if (validation == null) {
          return const SizedBox();
        }
        if (validation.isInvalid) {
          return Padding(
            padding: const EdgeInsets.only(left: 24),
            child: Text(
              validation.validations.values
                  .where((element) => element.isInvalid)
                  .first
                  .error!,
              style: _getErrorStyle(),
            ),

        }
        return const SizedBox.shrink();
      },
    ),
