Nested env not working.

[kencana16]

i have class like this

@Environment("cloud")
@Injectable(as: IClassA)
class ClassA {
  final ClassB classb;

  ClassA(this.classb);
}

@Environment("cloud")
@Injectable()
class ClassB {}

@Environment("local")
@Injectable(as: IClassA)
class OtherClassA {
  OtherClassA();
}

the generated file become

gh.factory<ClassB>(
        () => ClassB(),
        registerFor: {_cloud},
);
gh.factory<IClassA>(
        () => ClassA(
          gh<ClassB>(),
        ),
        registerFor: {_cloud},
);
gh.factory<IClassA>(
        () => OtherClassA(),
        registerFor: {_local},
);

when ClassB only registered if environment contain _cloud, so ClassA factory become error because classB doesn't registered in getIt.
