Form labels not updating when language is changed

Description

I'm experiencing an issue where form field labels don't update automatically when the application language is changed using Nylo's localization system. The form uses trans() for internationalization, but the labels remain in the previous language until the form is recreated.

Code Example

Form definition:

class LoginForm extends NyFormData {
  LoginForm({String? name}) : super(name ?? "login");

  @override
  List<Field> fields() => [
    Field.email(
      "Email",
      label: trans('login.email_placeholder'),
      validate: FormValidator.rule("email", message: trans('errors.email')),
    ),
    Field.password(
      "Password",
      label: trans('login.password_placeholder'),
      validate: FormValidator.password(
        strength: 2, 
        message: trans('errors.password')
      ),
    ),
  ];
}

Page implementation:

class _LoginPageState extends NyPage<LoginPage> {
  final form = LoginForm(); // Form created once

  @override
  get init => () {};

  @override
  Widget view(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: NyForm(
          form: form,
          footer: Button.primary(
            text: trans('login.login_button'),
            submitForm: (form, data) {
              // Login logic
            },
          ),
        ),
      ),
    );
  }
}

Current Behavior

1. Form loads with correct labels in the current language
2. When language is changed using changeLanguage('es') or similar
3. Other UI elements update correctly (like button text)
4. Form field labels remain in the previous language

Expected Behavior

Form field labels should automatically update to reflect the new language when changeLanguage() is called.

Attempted Solutions

Moving form creation to view()

@override
Widget view(BuildContext context) {
  final form = LoginForm(); // Create form on each rebuild
  return NyForm(form: form, ...);
}

Result: Labels update correctly, but form data is lost on each rebuild.

Questions

1. Is there a built-in way to refresh form labels when language changes?
2. Should forms automatically listen for locale changes?
3. What's the recommended approach for handling this scenario?

Would appreciate any guidance on the best approach to handle this scenario while maintaining data persistence and following best practices.

Hi @ElAdrixHD,

I'll take a look into this.
It sounds like a state issue.
