MapboxMaps.MapError(errorDescription: "Locale: ro (fixed) is currently not supported")

Nobody has claimed this yet.

Hi everyone, I experience an error when I use l10n for internationalization stuff for my flutter app.
Currently, it supports '**en**', '**fr**', '**ro**' but when I change for '**_ro_**', the MapWidget got an error and crash the app. Here is the IOS stack that I have :

```
flutter: unhandled element filter; Picture key: Svg loader
* thread #1, queue = 'com.apple.main-thread', stop reason = Fatal error: 'try!' expression unexpectedly raised an error: MapboxMaps.MapError(errorDescription: "Locale: ro (fixed) is currently not supported")

Target 0: (Runner) stopped.
```

For Android, I have the same error too.

For more information, I have this configuration for localization in `main.dart` :
```
localizationsDelegates: const [
S.delegate,
CountryLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
FormBuilderLocalizations.delegate,
PhoneFieldLocalization.delegate,
],
locale: localeLogic.locale,
supportedLocales: S.delegate.supportedLocales,
```

Has anyone ever had problems with internationalization for this flutter package ? And maybe, is there a way to force language selection for the package ?

Thanks in advance :D !

Start with the localization configuration in main.dart and the MapWidget path that receives the app locale. Reproduce the crash using the ro locale on iOS or Android, then trace where the locale is passed to MapboxMaps. Done means Romanian localization no longer crashes the map, or the package reports a supported-language limitation without terminating the app.
