registerFactoryParam with more than 2 input params

Hi
It is a good idea to have this registerFactoryParam. It was a missing part of get_it to become a complete DI tools for Flutter. There is still some improvement that we can do here. Right now get_it doesn't support constructor injection very well and you have to use property injection (constructor injection in some cases like testing is a better practice than property injection).
The registerFactoryParam can be a good solution for solving this problem but it's input parameters now has limits. This limit can cause problem in cases like this.
Here is a sample code works perfectly, but if your input parameters can't be more than 2 which limits this.

class A {}

class B {}

class C {
  A a;
  B b;
  int num1;
  int num2;

  C(this.a, this.b, this.num1, this.num2);
}

main() {
  GetIt.I.registerFactory<A>(() => A());
  GetIt.I.registerFactory<B>(() => B());
  GetIt.I.registerFactoryParam<C, int, int>(
      (param1, param2) => C(GetIt.I<A>(), GetIt.I<B>(), param1, param2));

  C c = GetIt.I.get<C>(param1: 1, param2: 2);
}

Hi, sorry for not looking into this earlier, but I had some mental health problems the last half year.

Did you have a look at the injectable package that uses get_it ?

If someone stumbles around this.
One hacky way to get around this is to create a class with the elements you want, and pass in the class.
