FIrebaseAuth verifyPhoneNumber crash in flutter IOS - ios

Question

I got this error when i call verifyPhoneNumber method:
My code works fine in android. Only in IOS it throws me this error. I checked a lot of issues on stackoverflow and github and have made sure that my GoogleService-Info.plist is in the right folder. I imported GoogleService-Info.plist through Xcode only and it is also added in CopyBundleResources section in Xcode-> Runner -> BuildPhases. Also a lot of places I saw that I need to add REVERSED_CLIENT_ID in URL Types in Xcode. Done this and also checked Info.plist that my REVERSED_CLIENT_ID is added correctly.
I have done everything but still don't know what is causing the issue.
My code for mobile auth:
import 'package:firebase_auth/firebase_auth.dart';
import 'package:[**package_name**]/functions/typedef.dart';
import 'package:[**package_name**]/helpers/log_helper.dart';
class MobileAuth{
MobileAuth(
this.mobileNumber,
this.afterCodeSent,
this.verificationCompleted,
this.verificationFailed,
this.autoTimeout,
this.ifOtpFailed,
this.afterOtpSend);
final String mobileNumber;
final AfterCodeSent afterCodeSent;
final PhoneAuthVerificationCompleted verificationCompleted;
final PhoneAuthVerificationFailed verificationFailed;
final AuthFailedMessage autoTimeout;
final AuthFailedMessage ifOtpFailed;
final AfterOtpSend afterOtpSend;
FirebaseAuth auth = FirebaseAuth.instance;
/// to sent the code to the given mobile number
void initialAuth() async{
await auth.verifyPhoneNumber(
phoneNumber: mobileNumber,
verificationCompleted: (PhoneAuthCredential credential) {
verificationCompleted(credential);
},
verificationFailed: (FirebaseAuthException e) {
verificationFailed(e);
},
codeSent: (String verificationId, int? resendToken) {
afterCodeSent(verificationId, resendToken ?? 0);
},
timeout: const Duration(seconds: 15),
codeAutoRetrievalTimeout: (String verificationId) {
autoTimeout(verificationId);
},
);
}
/// check otp by submitting to the auth api
void verifyOtp(String smsCode, String verificationId) async{
// Create a PhoneAuthCredential with the code
PhoneAuthCredential credential = PhoneAuthProvider.credential(verificationId: verificationId, smsCode: smsCode);
// Sign the user in (or link) with the credential
try{
UserCredential userCredential = await auth.signInWithCredential(credential);
LogHelper.log("After sending OTP: ${userCredential.user?.uid}");
afterOtpSend(userCredential);
}catch(e){
LogHelper.log("After sending OTP ${e.toString()}");
ifOtpFailed(e.toString());
}
}
void resendVerificationCode(int token) {
auth.verifyPhoneNumber(
forceResendingToken: token,
phoneNumber: mobileNumber,
verificationCompleted: (PhoneAuthCredential credential) {
verificationCompleted(credential);
},
verificationFailed: (FirebaseAuthException e) {
verificationFailed(e);
},
codeSent: (String verificationId, int? resendToken) {
afterCodeSent(verificationId , resendToken ?? 0);
},
timeout: const Duration(seconds: 60),
codeAutoRetrievalTimeout: (String verificationId) {
autoTimeout(verificationId);
},
);
}
}
And i call this in my statefull widget init method like this:
#override
void initState(){
String mobileNumber = "${widget.countryCode} ${widget.phoneNumber}";
mobileAuth = MobileAuth(mobileNumber, afterCodeSent,
verificationCompleted, verificationFailed, autoTimeout, ifOtpFailed, afterOtpSend);
sendOtpToPhone();
}
void sendOtpToPhone(){
mobileAuth.initialAuth();
}
The code works fine in android debug and release mode, so I only have this issue in IOS. Crashes when I call sendOtpToPhone(); -> mobileAuth.initialAuth(); -> auth.verifyPhoneNumber();
I have know for sure that auth.verifyPhoneNumber(); is only causing the error, because if I comment that segment of code then no crash is happening.
Also have tried flutter clean and i am using firebase_auth: 3.3.16 . Also tried it with 3.3.14.
