I made the login system, but when opening the screen that has the firebase, the application closes immediately. Is it necessary to add some information in firebase core?

What about adding firebase db ??

I added it and it worked correctly, do you know how to join the otp verification together with the email verification? To go all to a single account? Thank you very much for this tutorial
