No register type error

[oscarshaitan]

I get this error

No type XUseCase is registered inside GetIt.
 Did you forget to pass an instance name? 
(Did you accidentally do  GetIt sl=GetIt.instance(); instead of GetIt sl=GetIt.instance;
did you forget to register it?)

get it dont find the XUsCase but is already registered

sl.registerLazySingleton<XUseCase >(() => XUseCase (sl()));

[escamoteur]

looks good to me, what is the constructor of XUseCase doing? can you show me the code where you get the exception?

[oscarshaitan]

class XUseCase {
  final XRepository repository;

  XUseCase (this.repository);

  Future<Either<Failure, dynamic>> call(String param1, String param2) async {
    return repository.run(param1, param2);
  }
}

is to simple usecase
that use case is needed on a bloc an I call the use case with
XUseCase xUsecase = sl.get<XUseCase>();

[oscarshaitan]

and was working fine I have at least 15 types registered the only thing new is I update to get_it: ^5.0.1

[escamoteur]

What should this here do sl()?

[oscarshaitan]

sorry thats my get_it instance :D
final sl = GetIt.instance..allowReassignment = true;

[escamoteur]

yeah but you call it while passing to the constructor:
sl.registerLazySingleton<XUseCase >(() => XUseCase (sl()));

[oscarshaitan]

this
sl.registerLazySingleton<XUseCase >(() => XUseCase (sl()));
in on the setup just like the guide.
in this case that bloc is not provide by the get_it I'm getting the usecase just when I needed not on the constructor

[escamoteur]

yeah, so you are expecting that the sl() returns you a registered instance of XRepository ? could it be that the constructor of XRepository tries to access `XUsecase'

[oscarshaitan]

no, the repo dont have any instance of sl or the usecase

[oscarshaitan]

an yesh Im specting sl return a Xrpository tha tis also registered
sl.registerLazySingleton<XRepository >(() => XRepository (sl()));

[oscarshaitan]

also tht repository dependecy is registered too. was working just fine until yesterday that I update to get_it: ^5.0.1 also I made a full clean and restaert everything.
btw is happening only on ios

[escamoteur]

I recommeds always use sl() which is better to read.

Now, that seems pretty weird that it only happens on iOS because get_it doesn't use any system functions.

could it be that it's a timing issue? that somehow on iOS a part of code gets executed that tries to access XUsecase before it it registered?
Did you check in the stack trace when the exception happens where the sl() is called?

[oscarshaitan]

I dont think is the timing cuz all those register are happening before the runApp() call so is weird indeed and more wierd that os happening only on ios

import 'injection_container.dart' as di;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();

  di.init();

  runApp(MyApp());
}

[escamoteur]

would you mind joining me in a zoom call that I can look at your project?
That is honestly too weird.

[oscarshaitan]

sure!

[oscarshaitan]

@escamoteur I clean flutter reset/invalidate cache and now is working Thanks!
