Flutter: Not able to use nested models with Entities. (Entities, Models, Equatable, Flutter, Dart, json_serializable,Json Serialization)

I have two file for a single data i.e Entity and Model. To separate the entire logic from each other and to follow best practices. Whenever I am trying to use nested Entities and parsing through @JsonSerializable it's showing me error.

Note: I have tried @JsonConverter too. It's not working.

I'm sure I'm missing something over there but can't get it. Please help.

test_entity.dart

class TestEntity extends Equatable {
final String id;
final List<AddressEntity> address;

const TestEntity({
required this.id,
required this.address,
});
@override
List<Object?> get props => [
    id,
    address,
  ];
}

test_model.dart

part 'test_model.g.dart';

@JsonSerializable(explicitToJson: true)
class TestModel extends TestEntity {
const TestModel({
required String id,
required List<AddressModel> address,
}) : super(
      id: id,
      address: address,
    );
factory TestModel.fromJson(Map<String, dynamic> json) =>
  _$TestModelFromJson(json);

Map<String, dynamic> toJson() => _$TestModelToJson(this);
}

address_entity.dart

class AddressEntity extends Equatable {
 final String id;
 final String title;

const AddressEntity({
 required this.id,
 required this.title,
});
@override
List<Object?> get props => [
    id,
    title,
  ];
}

address_model.dart

part 'address_model.g.dart';

@JsonSerializable()
class AddressModel {
 final String id;
 final String title;

 AddressModel({
  required this.id,
  required this.title,
 });

 factory AddressModel.fromJson(Map<String, dynamic> json) =>
    _$AddressModelFromJson(json);

 Map<String, dynamic> toJson() => _$AddressModelToJson(this);
 }

When I use AddressModel instead AddressEntity

Here is the Snap of Code
