i like to know how you make this strategy on hive

[rizzi37]

here is example~

void main() async {
  Hive.registerAdapter(PersonAdapter());
  var persons = await Hive.openBox<Person>('personsWithLists');
  await persons.clear(); // here clear before data, if no await, your data is no useful until you refresh your app in flutter or lost

  var mario = Person('Mario');
  var luna = Person('Luna');
  var alex = Person('Alex');
  persons.addAll([mario, luna, alex]);

  mario.friends = HiveList(persons); // Create a HiveList
  mario.friends.addAll([luna, alex]); // Update Mario's friends

  /// create in hivelist
  alex.friends = HiveList(persons); // Create a HiveList
  alex.friends.addAll([luna]); // from mario get alex friend  luna
  print(mario.friends);


  luna.delete(); // Remove Luna from Hive
  print(mario.friends); // HiveList updates automatically
}

in my app only different is use multiple box relationship.. here is in one box.
