ValidationBuilder already supports using "local" locales by providing them as constructor parameter: ```dart ValidationBuilder(locale: customLocale) ``` If you need more "flexibility" you can write some helper function like this and...

You can provide custom validators using [`.add` method](https://pub.dev/documentation/form_validator/latest/form_validator/ValidationBuilder/add.html) like: ```dart ValidationBuilder(optional: true) ..add((value) => (double.tryParse(value) ?? 0.0) < someDoubleValue ? null : 'Value has to be less than $someDoubleValue'); ```...
