HiveError (HiveError: The same instance of an HiveObject cannot be stored with two different keys

**Steps to Reproduce**
I've added an hive object to my Flutter Project. When I use it with provider and create some object and put.

Getting Error: `HiveError (HiveError: The same instance of an HiveObject cannot be stored with two different keys ("0" and "1").)
`

**Code sample**
```
import 'package:hive/hive.dart';

part 'book.g.dart';

@HiveType(typeId: 7)
class Book extends HiveObject {
Book({
required this.orderNo,
required this.name,
required this.author,
required this.fileName,
required this.img,
required this.lastPage,
required this.lastOpen,
});

@HiveField(0)
int orderNo;

@HiveField(1)
String name;

@HiveField(2)
String author;

@HiveField(3)
String fileName;

@HiveField(4)
String img;

@HiveField(5)
double lastPage;

@HiveField(6)
int lastOpen;
}

```

I know the last page looks weird by actually I am save it as `scroll controller offset`
and I know that lastOpen should string or date format, I use epoch format like 164112312334

**Version**
- Platform: iOS
- Flutter version: [3.0.5]
- Hive Flutter version: [1.1.0]

The report names no repository files or tests. Reproduce the sample with Hive Flutter 1.1.0 and Flutter 3.0.5, then trace how the same HiveObject receives keys during storage. Done means identifying the cause of the conflicting keys and documenting a verified resolution or a clearly scoped code change.
