NoSuchMethodError: Class '_InternalLinkedHashMap<String, dynamic>' 没有实例 getter 'title'

Question

我对这段代码要做的事情我没有解决这个问题的想法main 我需要的是从 mysql 数据库中获取数据并放入 hive.box 数据库

void main() async {
  await Hive.initFlutter();
  runApp(HomePage());
}

这是我对 API mysql 数据库和 hivebox getAlldata

  Box box;
  List list = [];

  Future openBox() async {
    var document = await getApplicationDocumentsDirectory();
    Hive.init(document.path);
    box = await Hive.openBox<TodoModel>(todoBoxName);
    return;

  }
Future getAllData() async {
    await openBox();

    String url = "http://dhoido.com/sttt/tes/viewHive.php";

    try{
      var response = await http.get(Uri.parse(url));
      var _jsonDecode = jsonDecode(response.body);
      // setState(() {
      //   var resBody = json.decode(response.body);
      //   list = resBody;
      // });

      await putData(_jsonDecode);

    } catch (SocketException) {
      print(SocketException);

    }
    // get data from database
    var mymap = box.toMap().values.toList();
    if (mymap.isEmpty){
      list.add('empty');
    }else{
      list = mymap;
    }
    return Future.value(true);

  }

这是我放入数据库 putData

Future putData(data) async {
    await box.clear();
          //insert data
      for(var d in data) {

     d = {
          "title":d.title.cast<int>(),
          "detail":d.detail.cast<int>(),
           "isCompleted":true,
        };

        box.add(d);
      }


  }

这是我的未来建造者列表futurebuilder

child: FutureBuilder(
          future: getAllData(),
          builder: (context, snapshot){
            if (snapshot.hasData){
              if (list.contains('empty')){
                return Text(
                    'No Data'
                );
              }else{
                return Column(
                  children: [
                    SizedBox(
                      height: 25,
                    ),
                    Image(
                      image: NetworkImage(
                        'http://dhoido.com/sttt/images/8.jpg',
                      ),
                    ),
                    Expanded(
                        child: RefreshIndicator(
                          onRefresh: updateData,
                          child: ListView.builder(
                              itemCount: list.length,
                              itemBuilder: (ctxt, index){
                                return ListTile(
                                  title: Text(
                                      "${list[index]['title']}"
                                  ),
                                  trailing: Text(
                                      "${list[index]['detail']}"
                                  ),
                                );
                              }),
                        )
                    )
                  ],
                );

              }

            }else {
              return CircularProgressIndicator();
            }
          },

        ),

这是我的模型 todomodel

import 'package:hive/hive.dart';

part 'todo_model.g.dart';

@HiveType()
class TodoModel  extends HiveObject{
  @HiveField(0)
  final String title;
  @HiveField(1)
  final String detail;
  @HiveField(2)
  final bool isCompleted;

  TodoModel({this.title, this.detail, this.isCompleted});
}

这是错误 title
