Firebase phone auth not initiating OTP only in release mode but works on Debug mode even after added sha1 for release mode

[MuthuSubramaniam]

Steps how I implemented.

VERSION: firebase_auth: ^0.18.0+1

As advised, I implemented all the way. It was quite good in debug mode. Unfortunately its not working in release mode even I added my debug and release sha1 keys in firebase console.

Step 1. Coding part is here

          final PhoneVerificationCompleted verificationCompleted =
                 (PhoneAuthCredential user) {
              successMessage('Your phone number verified successfully!');
             _loginNotifier.validate();
          };
         final PhoneVerificationFailed verificationFailed = (FirebaseAuthException authException) {
              errorMessage('Phone number verification failed. Code: ${authException.code}. Message: 
             ${authException.message}');
        };

         final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
                (String verificationId) {
             this._verificationId = verificationId;
            print("time out");
         };

         firebaseAuth = FirebaseAuth.instance;
         firebaseAuth.verifyPhoneNumber(
               phoneNumber: '+$_phoneWithCC',
               timeout: const Duration(seconds: 60),
               verificationCompleted: verificationCompleted,
               verificationFailed: verificationFailed,
               codeSent: codeSent,
               codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);

Step 2: Added sha1 key's in console

Error I am getting:

As I said, in debug mode all good as expected But in release mode, after initiating the otp function, immediately PhineVerificationFailed with null message and null code.

If still anything I missed please advice. Thanks all

@Sreejithtechno any update?

[alvinvin00]

did you update your google-services.json after adding those keys? If you haven't go update the JSON and rebuild

[MuthuSubramaniam]

yes its up to date

[alvinvin00]

I remember i encountered this problem before. Try adding the SHA256 hash on Firebase Console, don’t forget to update your google_services.json on your project after you added them.
