define fromJson ,fromMap with key

[moham96]

When my class is extending HiveObject I have access to key using the getter defined in HiveObject but after sending the class instance through the network as json I need to convert it back to a model using Model.fromMap(Map<String,dynamic> map) but I can't set the key since it is private and the HiveObjectMixin is not defining a setter

class User extends HiveObject {
  final String name;

  User({required this.name});

  factory User.fromMap(Map<String, dynamic> map) {
    return User(
      name: map['name'], // <<here I need to set key as well but I can't
    );
  }
}

How can I define a fromMap factory that returns a model with the sam key in the map/json ?
