【问题描述】：
我正在尝试从服务器解析复杂的 json 数据，如下所示
{
"success": true,
"data": {
"user": {
"_id": "6103a8036da3e840111c1365",

},

}
}
我已经为这个类建模来解析这些数据
class UserDetails {
String? id;
bool? mobileVerified;
String? resentOtp;
String? email;
String? regmail;
List<UserDeviceDetails>? deviceDetails;
List<UserLocationDetails>? locationDetails;
List<String>? deviceId;
String? userValidCode;
String? leadstatus;
bool? dailyMail;
bool? weeklyMail;
bool? promotionalMail;
bool? trValid;
String? userType;
String? createdAt;
String? updatedAt;
String? hubspotid;
String? googleContactId;
String? malContent;
int? otp;
bool? emailVerified;
List<UserAccount>? accounts;
UserDetails();
Map<String, dynamic> toMap() {
var map = <String, dynamic>{
"_id": id,
"mobile_verified": mobileVerified,
"resend_otp": resentOtp,
"email": email,
"reg_email": regmail,
"device_details": deviceDetails,
"location_details": locationDetails,
"device_id": deviceId,
"user_valid_code": userValidCode,
"leadstatus": leadstatus,
"daily_mail": dailyMail,
"weekly_mail": weeklyMail,
"promotional_mail": promotionalMail,
"tr_valid": trValid,
"user_type": userType,
"created_at": createdAt,
"updated_at": updatedAt,
"hubspotid": hubspotid,
"google_contact_id": googleContactId,
"mal_content": malContent,
"otp": otp,
"email_verified": emailVerified,
"accounts": accounts,
};
return map;
}
UserDetails.fromMap(Map<String, dynamic> map) {
id = map["_id"];
mobileVerified = map["mobile_verified"];
resentOtp = map["resend_otp"];
email = map["email"];
regmail = map["reg_email"];
deviceDetails = List<UserDeviceDetails>.from(map["device_details"].map((x) => UserDeviceDetails.fromMap(x)));
locationDetails = List<UserLocationDetails>.from(map["location_details"].map((x) => UserLocationDetails.fromMap(x)));
deviceId = List<String>.from(map["device_id"].map((x) => x));
userValidCode = map["user_valid_code"];
leadstatus = map["leadstatus"];
dailyMail = map["daily_mail"];
weeklyMail = map["weekly_mail"];
promotionalMail = map["promotional_mail"];
trValid = map["tr_valid"];
userType = map["user_type"];
createdAt = map["created_at"];
updatedAt = map["updated_at"];
hubspotid = map["hubspotid"];
googleContactId = map["google_contact_id"];
malContent = map["mal_content"];
otp = map["otp"];
emailVerified = map["email_verified"];
accounts = List<UserAccount>.from(map["accounts"].map((x) => UserAccount.fromMap(x)));
}
}
我得到了对我在下面创建的对象的响应。但是每当我尝试访问帐户信息时，我都会得到 ['UserAccount' 的实例]。我在哪里获得适当的用户价值。
if (response.statusCode == 200) {
print("response body");
ApiResponseBody body =
ApiResponseBody.fromJson(convertResponseToJson(response));
if (body.success == true) {
print('this is bodydata : ${body.data.toString()}');
UserDetails userDetails = UserDetails.fromMap(body.data["user"]);
print('This is userdetails : ${userDetails.regmail} '); // gets result as test1@gmail.com
print('this is userAccount : ${userDetails.accounts}'); // gets [Instance of UserAccount']
}
我错过了什么吗？我还在学习flutter，任何建议都会有所帮助
