i fixed it by setting timeout: 0 https://stackoverflow.com/questions/65803670/error-receiving-broadcast-intent-when-using-smsretriever

[darshankawar]

and don't set timeout

@guvanch07 Where in the code are you setting / not setting the timeout ? Can you provide a reproducible code sample ? By not setting the timeout, are you referring to codeAutoRetrievalTimeout ? Also, can you provide the entire crash log ?

[guvanch07]

@darshankawar no, i am not referring to codeAutoRetrievalTimeout

Future<void> _otpToPhoneAuth({
    required String phoneNumber,
    required String localeCode,
    int? forceResendingToken,
    bool isResend = false,
  }) async {
    await _auth.verifyPhoneNumber(
      phoneNumber: phoneNumber,
      verificationCompleted: (PhoneAuthCredential credential) async {
        await _auth.signInWithCredential(credential);
      },
      verificationFailed: (FirebaseAuthException e) {
        Sentry.captureMessage(
            'Phone verification error: ${e.code} ${e.message ?? ''}');
        log(e.code, name: 'sendSms');
        _errorHandlerVerify(e.message ?? '', e.code);
      },
      codeAutoRetrievalTimeout: (String verificationId) {},
      forceResendingToken: forceResendingToken,
      timeout: const Duration(seconds: 0),         // i mean this timeout
      codeSent: (String verificationId, int? resendToken) async {.....},
    );
  }

to input sms code i use pinput package

                   Pinput(
                    length: 6,
                    androidSmsAutofillMethod:
                        AndroidSmsAutofillMethod.smsUserConsentApi,
                    submittedPinTheme: pinTheme(
                        signUpSmsTimerWatch.errorText == null
                            ? AppColorsV3.syslightonsurface
                            : AppColorsV3.syslighterror),
                    defaultPinTheme: pinTheme(AppColorsV3.syslightoutline),
                    focusedPinTheme: pinTheme(AppColorsV3.syslightprimary),
                    errorPinTheme: pinTheme(AppColorsV3.syslighterror),
                    hapticFeedbackType: HapticFeedbackType.mediumImpact,
                    errorTextStyle: const TextStyle(color: Colors.red),
                    errorText: signUpSmsTimerWatch.errorText,
                    closeKeyboardWhenCompleted: true,
                    pinputAutovalidateMode: PinputAutovalidateMode.onSubmit,
                    mainAxisAlignment: MainAxisAlignment.spaceAround,
                    onCompleted: (value) {....}
                    autofocus: true,
                  ),

@guvanch07 pinput is a third party package. I tried your code sample above in the plugin example, with which I wasn't able to replicate the reported error. Can you try the same and check if issue persists using plugin example ?

https://github.com/firebase/flutterfire/blob/759684b1b445bf238e9644ef1dc495cdc6a55dd8/packages/firebase_auth/firebase_auth/example/lib/auth.dart#L435

[guvanch07]

did you hide timeout: param in the code https://github.com/firebase/flutterfire/issues/12170#issuecomment-1900213993? if you didn't hide, please hide the line timeout: const Duration(seconds: 0) and try again timeout is optional and need to test only android devises where has a autofill functionality

[darshankawar]

@guvanch07 Looking at the error log, the crash seems to be occuring in native pointing to the sms api act=com.google.android.gms.auth.api.phone.SMS_RETRIEVED Is it possible for you to try and replicate the behavior only using the plugin example (without pinput package) and by commenting out the timeout property as you mentioned above ?

[guvanch07]

yes, it looks like Pinput package's problem i found issue that is related to the error i got https://github.com/Tkko/Flutter_Pinput/issues/105

[darshankawar]

Closing based on above, as not flutterfire issue.
