Flutter Hive model have enum type but not able to put/set value in enum with hive-field

Question

I want a hivemodel class which is contain enum as field but hive is not able to put set value.

CONTACTTYPE is enum:

@freezed
@HiveType(typeId: 7, adapterName: "FriendGroupEntityAdapter")
@freezed

class FriendsGroupEntity with _$FriendsGroupEntity {

  const factory FriendsGroupEntity({
 @HiveField(0)  int userId,
  @HiveField(1)  @Default(CONTACTTYPE.loop) CONTACTTYPE contactType,
  @HiveField(2)   String contact,
  @HiveField(3)   int id,
  @HiveField(4)   int value,
  @HiveField(5)   int value2,
  @HiveField(6)   int value3,
  @HiveField(7)   int value7,
});

Here CONTACTTYPE.loop is an enum and I want to store it into hive, and got an error which I attach.

Is there any way for enum in hive?

Please follow this approach

import 'package:hive/hive.dart';
    
    part 'myrepresentation.g.dart';
    
    @HiveType(typeId: 1)
    class FriendsGroupEntity extends HiveObject {
      @HiveType(0)
      final String id;
    
      @HiveType(1)
      final Foo foo;
      MyRepresentation({required this.id, required this.foo});
    }
    
    @HiveType(typeId: 2)
    enum Foo {
      @HiveField(0)
      foo,
      @HiveField(1)
      bar,
    }
