How to test 'Google Sign-in' on Android device

Hi. I was following this article
https://docs.flutterflow.io/data-and-backend/firebase/authentication/google-sign-in

Step 6 says you need to add the authorized domain which works easily on the browser. But I want to test my app on my Android device but the google sign-in doesn't work on my device probably because it has a different domain. The way I test my app for now is to download the apk and install it on my device manually.

How can I test google sign-in on my device?
