Dart: Custom "copyWith" method with nullable properties

I'm trying to create a "copyWith" method for my class, and it works with most scenarios.

The problem is when I try to set a nullable property to null, because my function cannot recognize whether it's intentional or not.

Ex.:

class Person {
  final String? name;
  
  Person(this.name);
  
  Person copyWith({String? name}) => Person(name ?? this.name);
}

void main() {
  final person = Person("Gustavo");
  print(person.name); // prints Gustavo
  
  // I want the name property to be nul
  final person2 = person.copyWith(name: null);
  print(person2.name); // Prints Gustavo
}

Does anyone knows some workaround for this situation? This is really bothering me and I don't know how to avoid this situation.

Inspired by @jamesdlin answer:

All you need to do is provide a wrapper around. Take this example in consideration:

class Person {
  final String? name;

  Person(this.name);

  Person copyWith({Wrapped<String?>? name}) =>
      Person(name != null ? name.value : this.name);
}

// This is all you need:
class Wrapped<T> {
  final T value;
  const Wrapped.value(this.value);
}

void main() {
  final person = Person('John');
  print(person.name); // Prints John

  final person2 = person.copyWith();
  print(person2.name); // Prints John

  final person3 = person.copyWith(name: Wrapped.value('Cena'));
  print(person3.name); // Prints Cena

  final person4 = person.copyWith(name: Wrapped.value(null));
  print(person4.name); // Prints null
}
