[Flutter] Flutter Unit Test With Localization

I have a utility class that relies on the context in order to translate the output. Something along the lines of :

static String doSomeLogicAndTranslate(String firstArg, BuildContext context) {
//...
return AppLocalizations.of(context)!.someKey;
}


Now, I want to be able to write some unit tests for this class, but since the second argument is the context, I'm having a hard time doing so.

What I have tried so far:

• 
  Mocking a BuildContext with Mockito (as described here) and passing that as the second argument --> Doesn't work as inside the localizations.dart file it returns null here
  
  static T? of<T>(BuildContext context, Type type) {
  final _LocalizationsScope? scope = context.dependOnInheritedWidgetOfExactType<_LocalizationsScope>(); /// Scope is null here
  return scope?.localizationsState.resourcesFor<T?>(type);
  }

I have tried looking around for any other solutions for this, but have not found anything substantial. This seems like it should be pretty straight forward, but it isn't.
