I tried to capture the SMS code inside verificationComplete callback but the PhoneAuthCredential's smsCode field returns null.

 Future<void> loginWithPhone(String phoneNumber,
      final OnSMSCodeSent onSMSCodeSent,
      final OnVerificationFailed onVerificationFailed) async {
    print("******** PHONE ********* $phoneNumber");
    return await _auth.verifyPhoneNumber(
        phoneNumber: phoneNumber,
        timeout: timeOut,
        codeSent: onSMSCodeSent,
        codeAutoRetrievalTimeout: (String verificationId) {},
        //ANDROID ONLY: Verify SMS Code automatically.
        verificationCompleted: (PhoneAuthCredential credential) async {
          // ANDROID ONLY!
          AppLogger.log(TAG,
              message: "Auto SMS Code Verification is Completed! OTP CODE = ${credential.smsCode}");
          // Sign the user in (or link) with the auto-generated credential
        await _auth.signInWithCredential(credential);
        },
        verificationFailed: onVerificationFailed,
    );
  
```}

and here is the log output 

`I/flutter ( 6777): │ [PhoneAuthHandler] Auto SMS Code Verification is Completed! OTP CODE = null`
