HiveObjects needs to be in the box

I have defined two boxes in `Hive` as follows:

```dart
@HiveType(typeId: 1)
class CartTable extends HiveObject {
@HiveField(0)
late int id;

@HiveField(1)
late String name;

@HiveField(2)
late String image;

@HiveField(3)
late HiveList orders;
}

@HiveType(typeId: 2)
class OrdersTable extends HiveObject {
@HiveField(0)
late int id;

@HiveField(1)
late String name;

@HiveField(2)
late String description;

@HiveField(3)
late int price;

@HiveField(4)
late String image;

@HiveField(5,defaultValue: '')
String? detail;

@HiveField(6,defaultValue: '')
String? note;

@HiveField(7,defaultValue: 1)
late int count;

@HiveField(8,defaultValue: '')
String? promotionCode;
}
```

Note:
Inside the `CartTable` box, there is another box named `OrdersTable` which should have a relationship with each other.

And I opened these two boxes in the `main.dart` file as follows:

```dart
await Hive.openBox('cart', encryptionCipher: HiveAesCipher(key));
await Hive.openBox('orders', encryptionCipher: HiveAesCipher(key));
```

Now, when I try to establish this relationship with the following code, it gives me the following error:

HiveObjects needs to be in the box 'orders'.

Here are the implemented codes:

```dart
Box _cartTable= Hive.box('cart');
Box _orders = Hive.box('orders');

CartTable? cart;

cart = CartTable()
..id = store.id
..name = store.name
..image = store.image;

cart.orders = HiveList(_orders);

final order = OrdersTable()
..id = menu.id
..name = menu.name
..description = menu.description!
..image = menu.image
..price = menu.price
..note=''
..detail=''
..promotionCode=''
..count = 1;

cart.orders.add(order);

cartTable.add(cart);

cart.save();
```
