Is injectable support class with Type Parameter ?

[azizarc88]

Heres the example

abstract class ExtendedClass {}

class FirstClasFromExtendedClass extends ExtendedClass {}

class SecondClasFromExtendedClass extends ExtendedClass {}

@Injectable()
class MainClass<T extends ExtendedClass> {
  /// can be either
  ///   - FirstClasFromExtendedClass
  ///   - SecondClasFromExtendedClass
  final T extendedClass;

  @factoryMethod
  static MainClass<FirstClasFromExtendedClass> createFirst(
          FirstClasFromExtendedClass extendedClass) =>
      MainClass(extendedClass);

  @factoryMethod
  static MainClass<SecondClasFromExtendedClass> createSecond(
          SecondClasFromExtendedClass extendedClass) =>
      MainClass(extendedClass);

  MainClass(this.extendedClass);
}

its generate error code

gh.factory<_i89.MainClass<dynamic>>(() =>
        _i89.MainClass<dynamic>.createFirst(
            gh<_i89.FirstClasFromExtendedClass>()));

and the correct one should be like this

gh.factory<_i89.MainClass<_i89.FirstClasFromExtendedClass>>(() =>
        _i89.MainClass.createFirst(
            gh<_i89.FirstClasFromExtendedClass>()));
    gh.factory<_i89.MainClass<_i89.SecondClasFromExtendedClass>>(() =>
        _i89.MainClass.createSecond(
            gh<_i89.SecondClasFromExtendedClass>()));

any suggestion or i do it wrong ?
