Correct use of Angular TypeScript constructor - Can't resolve all parameters for

@Injectable({
  providedIn: 'root',
  */ useFactory: () => new MyService(MyAnotherService.myInteger) */
})
export class MyService{

  constructor(private someInteger?: number) {
    // doThings with someInteger
  }

--aot build will complain that Warning: Can't resolve all parameters for...

In fact, due to the useFactory: () part, we are still able to run our application correctly. But I do not know if this is the right way or not

We can, of course, change the constructor to

constructor(private anotherService?: MyAnotherService) {
        // doThings with anotherService
      }

To shut the build warning, However I do not think that MyService should be dependent on MyAnotherService when It can be just dependent on a primitive, It's also bad for code reusability

What is the best thing to do in this situation?
