Feature Request: Multiple Error Messages Getter

[MatteMirror]

Environment

Version: latest

Description

Currently, the ReactiveFormFieldState class has a method that returns only the first error message encountered. Below is the existing implementation:

String? get errorText {
    if (control.hasErrors && _showErrors) {
      final errorKey = control.errors.keys.first;
      final validationMessage = _findValidationMessage(errorKey);

      return validationMessage != null
          ? validationMessage(control.getError(errorKey)!)
          : errorKey;
    }

    return null;
  }

Request

I would like to request an additional getter that returns a list containing all error messages. This enhancement would allow for better error handling and display in forms.

Proposed Implementation

 List<String> get errorMessages {
    if (control.hasErrors && _showErrors) {
      return control.errors.keys.map((errorKey) {
        final validationMessage = _findValidationMessage(errorKey);
        return validationMessage != null
            ? validationMessage(control.getError(errorKey)!)
            : errorKey;
      }).toList();
    }

    return [];
  }

Benefits

• Improved error handling: Users can see all validation errors at once.
• Enhanced user experience: More informative error messages help users understand and correct form input errors more efficiently.

Thank you for considering this feature request.
