you can do this. Switch to android in your terminal cd android. Then run the following command .gradlew signingReport

I bought the package and I'm really enjoying the tutorials! I'm having an issue here. The SMS text is never received. The Run log shows - W/FirebaseAuth(26995): [SmsRetrieverHelper] Timed out waiting for SMS. I confirmed that Google Play Integrity API is enabled (since Android Device Authentication API is no longer available). The recaptcha webpage briefly appears and goes away, but the SMS never shows up and I can't sign in. Any suggestions?

how can we show error messages on screen? for eg;- we got error invalid-phone or invalid-email so we have message corrosponding to this error in our exception directory but how can we show that msg on screen while authenticating on login screen.

You can directly call Get.showSnackBar() & pass error in it and you are good to go.

No need to use that. Simply follow the instructions and keep the dependencies updated.

[@jinkim3806]

wth, how do you store password for the same phone number, and other detials? how do we login with the same phone number as we have not set any password.

[@CodingwithT]

Without password using phone number you have to send OTP to users mobile and once verified, users can login. Storing passwords are not recommended

[@jinkim3806]

@@CodingwithT thanks, but what if i have other data to store into Firestone on the sign up how do i store the data when the user is verified,

[@CodingwithT]

You can do it inside signup, when authentication succeeded in adding user data. Or if you are using Authentication Repository and listening to userChanges, in this case you'll be auto redirected to some other page. So check accordingly

[@oneebkhan4453]

Great Tutorial. Any chance you show how to do the iOS part? I can't find any tutorials at all. Most of them outdated even if I find one.
