如何使用Flutter hive创建一个标记为fabourite按钮？

dependencies:
  hive: ^2.0.0
  hive_flutter: ^1.1.0

import 'package:hive/hive.dart';

part 'product.g.dart';

@HiveType(typeId: 0)
class Product extends HiveObject {
  @HiveField(0)
  late String name;

  @HiveField(1)
  late String description;

  @HiveField(2)
  late bool isFavorite;
}

import 'package:hive/hive.dart';
import 'package:hive_flutter/hive_flutter.dart';
import 'package:your_app/product.dart';

class HiveManager {
  static Future<void> initialize() async {
    await Hive.initFlutter();
    Hive.registerAdapter<Product>(ProductAdapter());
    await Hive.openBox<Product>('products');
  }
}

import 'package:hive/hive.dart';
import 'package:your_app/product.dart';

class YourPage extends StatelessWidget {
  Future<void> addToFavorites(Product product) async {
    final box = await Hive.openBox<Product>('products');
    product.isFavorite = true;
    await box.put(product.key, product);
  }

  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            final product = Product()
              ..name = 'Product Name'
              ..description = 'Product Description';
            addToFavorites(product);
          },
          child: Text('Add to Favorites'),
        ),
      ),
    );
  }
}
