Localisation-related crash when calling the getDescription method of the MandatoryConstraint class

[SamueleDassatti]

When calling the getDescription method of a MandatoryConstaint instance, the library throws the following exception "_TypeError (Null check operator used on a null value)" at line 74 of the l10n.dart file due to the forms_mandatory string apparently not being localised. This seems to be due to such string being return at line 375 of the forms.dart file.

Hi @SamueleDassatti , I sometimes get that issue but have not been able to understand the reason.
It can't be due just to a missing localization in one of the translated languages. In that case the system should fallback to the main language, in this case English.
And if you check the Italian translation against the English vocabulary, than smash should fails most of the times, since there are very few words translated. But it properly falls back to English.
While I am writing this it comes to my mind that maybe it has something to do with the forms only?

Anyways, hints, ideas and suggestions on how to solve this are very welcome. Thanks
