Bug: Recover the Injection by Inner Interface

[Bwolfs2]

Describe the bug
I am migrating from Modular 5.0 to Modular 6.0 and I'm encountering the following issue: I need to retrieve a concrete injection through one of its extended interfaces. For instance, Auth extends both ISignin and ISignout, and I need to retrieve it using Modular.get().

To Reproduce

import 'package:flutter/material.dart';
import 'package:flutter_modular/flutter_modular.dart';
import 'package:flutter_modular/modular_interfaces/route/modular_route.dart';
import 'package:flutter_test/flutter_test.dart';

abstract class Signin {
  String signin();
}

abstract class Signout {
  String signout();
}

class Auth implements Signin, Signout {
  @override
  String signin() {
    return 'Signin';
  }

  @override
  String signout() {
    return 'Signout';
  }
}

void main() {
  testWidgets('Test Inner Inject', (tester) async {
    final modularApp = ModularApp(
      module: CustomModule(),
      child: const AppWidget(),
    );

    await tester.pumpWidget(modularApp);

    await tester.pump();
    expect(Modular.get<ValueNotifier>(), isNotNull);
  });

  testWidgets('Extends Class Inject', (tester) async {
    final modularApp = ModularApp(
      module: CustomModule(),
      child: const AppWidget(),
    );

    await tester.pumpWidget(modularApp);

    await tester.pump();
    expect(Modular.get<Auth>(), isNotNull);
    expect(Modular.get<Signin>(), isNotNull);
    expect(Modular.get<Signout>(), isNotNull);
    expect(Modular.get<Signin>().signin(), 'Signin');
    expect(Modular.get<Signout>().signout(), 'Signout');
  });
}

///MOCKS
class CustomModule extends Module {
  @override
  List<Bind> get binds => [
        Bind.singleton<ValueNotifier>((i) => ValueNotifier<int>(0)),
        Bind.singleton((i) => Auth()),
      ];

  @override
  List<ModularRoute> get routes => [
        ChildRoute('/', child: (_, __) => Container()),
      ];
}

class AppWidget extends StatelessWidget {
  const AppWidget({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      routeInformationParser: Modular.routeInformationParser,
      routerDelegate: Modular.routerDelegate,
    );
  }
}

Expected behavior
When I use Modular.get(), it should return the Auth() implementation, but only with access to the function implemented in ISignin. I believe the test speaks for itself.

This is expected behavior.
This could be considered a previous Bug. Now we have the possibility of registering several factories of the same instance.
Now the records are 1 to 1.

Are you suggesting that I should do something like this? @jacobaraujo7

@override
 List<Bind> get binds => [
       Bind.singleton<ValueNotifier>((i) => ValueNotifier<int>(0)),
       Bind.singleton<Auth>(Auth.new),
       Bind.singleton<Signout >((i) => i.get<Auth>()),
       Bind.singleton<Signin>((i) => i.get<Auth>()),

     ];

[jacobaraujo7]

Yes!
