Flutter:配置文件数据中的 GetX 变量初始化问题

Flutter : GetX Variable initialise problem in Profile Data

我在我的 flutter 应用程序上使用 GetX 状态管理。我想从服务器获取用户的个人资料数据。这就是我创建配置文件模型 Class 和控制器屏幕的原因。但我不能。这是初始化的问题。

json 响应 -

{
  "riderId": 1,
  "riderName": "Ramiz Miah",
  "riderContact": "01787656565",
  "riderEmail": "ramiz@hotmail.com",
  "riderImgRef": ""
}

个人资料模型

class ProfileModel {
  int? riderId;
  String? riderName;
  String? riderContact;
  String? riderEmail;
  String? riderImgRef;

  ProfileModel(
      {this.riderId,
      this.riderName,
      this.riderContact,
      this.riderEmail,
      this.riderImgRef});

  ProfileModel.fromJson(Map<String, dynamic> json) {
    riderId = json['riderId'];
    riderName = json['riderName'];
    riderContact = json['riderContact'];
    riderEmail = json['riderEmail'];
    riderImgRef = json['riderImgRef'];
  }

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = <String, dynamic>{};
    data['riderId'] = riderId;
    data['riderName'] = riderName;
    data['riderContact'] = riderContact;
    data['riderEmail'] = riderEmail;
    data['riderImgRef'] = riderImgRef;
    return data;
  }
}

控制器

class ParofileController extends GetxController {
  RxMap<String, dynamic> profileDetails = <String, dynamic>{}.obs;
  //<============= Fetch and Assign DashBoard Today Details List

  void fetchandAssignProfileDetails() async {
    try {
      ProfileApiService().getProfileDetails().then((resp) {
       
          profileDetails.value = resp;
    
      }, onError: (err) {
        debugPrint(err.toString());
      });
    } catch (e) {
      debugPrint(e.toString());
    }
  }
}

和API服务

class ProfileApiService extends GetConnect {
  Future<ProfileModel?> getProfileDetails() async {
    Uri url = Uri.parse("${AppConfig.baseUrl}/Rider/GetRiderDetails");

    var response = await http.get(
      url,
    );

    if (response.statusCode == 200) {
      return ProfileModel.fromJson(jsonDecode(response.body));
    } else {
      throw Exception('Failed to load User Profile');
    }
  }
}

现在我的问题是如何在此处定义此变量 (RxMap<String, dynamic> profileDetails = <String, dynamic>{}.obs;),这就是它正常工作的原因

我解决了这个问题

 Rx<ProfileModel?> profile = ProfileModel().obs;

谢谢。
