Thank you for this Sir, you saved me a lot of stress especially regarding to SHA1. I was stuck with access block error but through your approach was able to resolve.

I have a question, the "react-native-google-sign" package free public version uses deprecated code for android. So, is it good for long run? I think google sign in will not work in future with this package.

Hello... please does this mean that google sign-in with superbase can only work in expo and not in bare react native cli?😢😢
