Flutter 无法获取跟踪ID

我试图在

PinCodeTextField

中获取跟踪ID以验证电子邮件，但收到此错误

“responseCode”：2，“消息”：“验证失败，请重试”

好的，对不起，我忘了和这个。这是我的回复电子邮件

import 'dart:convert';


ResponseVerifyEmail responseVerifyEmailFromJson(String str) => ResponseVerifyEmail.fromJson(json.decode(str));

String responseVerifyEmailToJson(ResponseVerifyEmail data) => json.encode(data.toJson());

class ResponseVerifyEmail {
    ResponseVerifyEmail({
        this.data,
        this.responseCode,
        this.message,
    });

    Data data;
    int responseCode;
    String message;

    factory ResponseVerifyEmail.fromJson(Map<String, dynamic> json) => ResponseVerifyEmail(
        data: Data.fromJson(json["data"]),
        responseCode: json["responseCode"],
        message: json["message"],
    );

    Map<String, dynamic> toJson() => {
        "data": data.toJson(),
        "responseCode": responseCode,
        "message": message,
    };
}

class Data {
    Data({
        this.trackingId,
    });

    String trackingId;

    factory Data.fromJson(Map<String, dynamic> json) => Data(
        trackingId: json["trackingId"],
    );

    Map<String, dynamic> toJson() => {
        "trackingId": trackingId,
    };
}
ResponseData responseDataFromJson(String str) =>
    ResponseData.fromJson(json.decode(str));

String responseDataToJson(ResponseData data) => json.encode(data.toJson());

class ResponseData {
  ResponseData({
    this.responseCode,
    this.message,
  });

  int responseCode;
  String message;

  factory ResponseData.fromJson(Map<String, dynamic> json) => ResponseData(
        responseCode: json["responseCode"],
        message: json["message"],
      );

  Map<String, dynamic> toJson() => {
        "responseCode": responseCode,
        "message": message,
      };
}

}

这就是我使用的提供者，这就是我使用逻辑的地方

我使用下面的代码访问跟踪ID

UserOnboardingModel\u UserOnboardingModel=UserOnboardingModel（）

Future pinCode（v）异步{
应答数据结果；
结果=等待存储库。VerifyEmailVerificationOnTP(
OTP验证模型(
trackingId:_userOnboardingModel.trackingId，pin:v））；
var text=result.message；
var responseCode=result.responseCode；
如果（响应代码==1）{
isVerified=true；
}else if（responseCode==2）{
isVerified=false；
}
信息=文本；
展示土司（信息）；
notifyListeners（）；
}

这就是我创建的视图

Consumer<OtpModel>(
          builder: (context, mOtpModel, child) => PinCodeTextField(
            onCompleted: (value) async{
              await mOtpModel.pinCode(value);
              if(mOtpModel.isLoading){
                return CircularProgressIndicator();
              }
              if(mOtpModel.isVerified){
                Navigator.pushNamed(context, SignUpView.SIGN_UP_ROUTE);
              }
            },
            mainAxisAlignment: MainAxisAlignment
                .spaceEvenly, //controls the space between each field
            pinTheme: PinTheme.defaults(
                borderWidth: 1.0,
                inactiveColor: Colors.black,
                activeColor: _greenColor,
                selectedColor: Colors.black), //used to format the input field

            textStyle: TextStyle(
                fontSize: 36,
                fontWeight: FontWeight.bold,
                fontFamily: 'Inter'),
            length: 4,
            onChanged: (value) {}, appContext: null,
          ),
        ),

消费者(
生成器：（上下文、mOtpModel、子项）=>PinCodeTextField(
未完成：（值）异步{
等待mOtpModel.pinCode（值）；
if（mOtpModel.isLoading）{
返回循环ProgressIndicator（）；
}
如果（mOtpModel.isVerified）{
Navigator.pushNamed（上下文，SignUpView.SIGN\u-UP\u-ROUTE）；
}
},
mainAxisAlignment:mainAxisAlignment
.space，//控制每个字段之间的间距
pinTheme:pinTheme.defaults(
边框宽度：1.0，
不活动颜色：颜色。黑色，
activeColor:\u绿色，
selectedColor:Colors.black），//用于设置输入字段的格式
textStyle:textStyle(
尺寸：36，
fontWeight:fontWeight.bold，
fontFamily:‘国际’，
长度：4，
onChanged:（值）{}，appContext:null，
),
),

因此，对于要移动到下一屏幕的
PinCodeTextField
，它已验证pin和跟踪ID，但抛出此错误：
responseCode]：2，“消息”：“验证失败，请重试”

请帮我弄清楚

    Future<void> pinCode(v) async {
    ResponseData result;
    result = await repository.verifyEmailVerificationOtp(
        OtpVerificationModel(
            trackingId: _userOnboardingModel.trackingId, pin: v));

    var text = result.message;
    var responseCode = result.responseCode;

    if (responseCode == 1) {
      isVerified = true;
    } else if (responseCode == 2) {
      isVerified = false;
    }
    message = text;
    showToast(message);

    notifyListeners();
  }

Consumer<OtpModel>(
          builder: (context, mOtpModel, child) => PinCodeTextField(
            onCompleted: (value) async{
              await mOtpModel.pinCode(value);
              if(mOtpModel.isLoading){
                return CircularProgressIndicator();
              }
              if(mOtpModel.isVerified){
                Navigator.pushNamed(context, SignUpView.SIGN_UP_ROUTE);
              }
            },

                activeColor: _greenColor,
                selectedColor: Colors.black), //used to format the input field
