After successfully register user go to the OTP screen where I enter my OTP but after clicking on button I get this:
type 'String' is not a subtype of type 'int?'
Here is the full message
[log] type 'String' is not a subtype of type 'int?'
[log] #0 new User.fromJson (package:marketingo/model/register_response.dart:117:31)

When I tried @Ivo answer int.parse(json["verification_code"]) then it given me this type 'int' is not a subtype of type 'String?'
Even I try to enter wrong OTP still I'm getting this.
Here is my code
My api for confirm Account
static Future<http.Response> confirmAccount(String userName, String verificationCode) async {
var url = Uri.parse('${baseUrl}confirmAccount');
var response = await http.post(url, body: {
"username": userName,
"verification_code": verificationCode,
});
return response;
}
Here is I'm calling my api
class PinCode extends StatefulWidget {
final String userName;
const PinCode(this.userName, {Key? key}) : super(key: key);
@override
State<PinCode> createState() => _PinCodeState();
}
class _PinCodeState extends State<PinCode> {
TextEditingController otpController = TextEditingController();
void _confirmAccount() async {
var connectivityResult = await (Connectivity().checkConnectivity());
if (connectivityResult == ConnectivityResult.wifi || connectivityResult == ConnectivityResult.mobile) {
Utils.showLoader(context);
ApiCall.confirmAccount(widget.userName, otpController.text).then((value) async {
if (value.statusCode == 200) {
if (json.decode(value.body)['success'] != null) {
if (json.decode(value.body)['success']) {
try {
RegisterResponse registerResponse = RegisterResponse.fromJson(json.decode(value.body));
} catch (error, stackTrace) {
log(error.toString());
log(stackTrace.toString());
}
Get.offAll(() => const BottomNav());
} else {
Utils.hideLoader(context);

After press on button app crash
CodePudding user response：
OTP is in String but u are assigning String To int which is not possible you can do this instead
int otp = int.parse('Your OTP here');
Thank you
CodePudding user response：
It's parsing Error,
Verification Code is int? datatype & Your OTP is in String. Parse your OTP in int? first & then do the rest of your code
int.parse(your otp);
CodePudding user response：
It looks like the phone response is an int and you are trying to get it by string.
as in your error message, it says your error at 117 lines that's means:
factory User.fromJson(Map<String, dynamic> json) => User(
firstName: json["first_name"],
username: json["username"],
email: json["email"],
type: json["type"],
address: json["address"],
roleId: json["role_id"],
verificationCode: int.parse(json["verification_code"]),
verified: json["verified"],
phone: json["phone"], // <-- here
mobile: json["mobile"],
lat: json["lat"],
lon: json["lon"],
categoryId: json["category_id"],
companyName: json["company_name"],
tradeLicense: json["trade_license"],
field: json["field"],
workTime: json["work_time"],
facebook: json["facebook"],
linkedIn: json["linkedIn"],
instagram: json["instagram"],
whatsApp: json["whatsApp"],
updatedAt: json["updated_at"] == null ? null : DateTime.parse(json["updated_at"]),
createdAt: json["created_at"] == null ? null : DateTime.parse(json["created_at"]),
id: json["id"],
balance: json["balance"] == null ? null : List<dynamic>.from(json["balance"].map((x) => x)),
);
and to solve this just convert it to String like:
phone: json["phone"].toString(),
