[FIXED] How can I restrict google login to my company's email domain (@company.com) in flutter?

Issue

Question

What is the best way to prevent users from using an email address that does not end in @mycompany.com from logging in to our internal app through Google auth?

I am new in flutter so can someone provide me the references or tutorial on how to implement this?

Solution

match user email with regex if true then company email else not company email.

RegExp(r"^[a-zA-Z0-9.a-zA-Z0-9.!#$%&'*+-/=?^_`{|}~]+@[mycompanyname.com]")
