在我的flutter hive上获取存储的数据使我陷入了这个错误：

════════ Exception caught by widgets library ═══════════════════════════════════

意外字符（位于字符2处）{id：2、网络：MTN，折扣：2、logo：mtncard.png} ^
以下是我的班级：

class Provider {
Provider({
required this.id,
required this.network,
required this.discount,
required this.logo,
});
final String id;
final String network;
final int discount;
final String logo;

factory Provider.fromJson(Map<String, dynamic> data) {
final id = data['id'] as String;
final network = data['network'] as String;
final discount = int.parse(data['discount']);
final logo = data['logo'] as String;
return Provider(
  id: id,
  network: network,
  discount: discount,
  logo: logo,
  );
 }
}

这是我的功能：

Future<List<dynamic>> LoadData() async {
final name = await Hive.box<dynamic>('my_db');
final result = name.values.toList();
print(result);
//print result is gotten perfectly from hive box
return name.values.toList();
}

这也是我未来的建设者

FutureBuilder<List<dynamic>>(
                                          future: LoadData(),
                                          builder: (BuildContext context,
                                              AsyncSnapshot snapshot) {
                                            if (snapshot.data == null) {
                                              return const Center(
                                                child: Text('loading'),
                                              );
                                            } else {
                                              return ListView.builder(
