Adding new rules with custom i18n error message about form-validator HOT 5 OPEN

Fixed in v0.1.6-next. I published as prerelease since there's some breaking changes.

from form-validator.

I'm thinking about using Map<String, String> for storing i18n messages rather than classes.

final localeData = <String, String>{
  'min_length': 'Must be at least {min} characters',
};

FormValidator.addLocale('en', localeData);

addLocale will merge new locale data with previous data, so you can append custom validation messages too.

FormValidator.addLocale('en', {
  'custom_validation': 'lorem ipsum dolor ...',
});

What do you think about that?

Some other methods would be added too, for example addMessage to add single message in multiple languages:

FormValidator.addMessage('custom_validation', {
  'en': '...',
  'fr': '...',
  ...
});

I think it would be a great solution for this problem 👍

Hello ! I've just tried this new version but i'm getting this error :

Unsupported operation: Cannot set value in unmodifiable Map

When the exception was thrown, this was the stack
#0      _ImmutableMap.[]=                              (dart:core-patch/immutable_map.dart:74:5)
#1      LocalizationImpl.addMessage             package:form_validator/src/localization_impl.dart:25

I couldn't found where this come from but maybe the Localdata is only accessible via "get" only somewhere.

Thanks for reporting. I think const <String, String>{ ... } maps become read-only maps.
