Flutter: Firebase Authentication & Google Sign In
Check out my Medium article "Flutter: Implementing Google Sign In".
In this article, I will be showing how to set up and implement Google Sign In using Firebase Authentication.
​
There are a number of articles out there showing how to implement sign-in or login in Flutter, but I am still writing this article because there has been a lot of changes in Flutter ( after the release of Flutter 1.7 ) as well as in the Firebase Google Sign In.
​
So, I recommend that you have a look at this article at least till the end of Google Sign In setup if you want to start building a new app using Firebase.
NOTE: The project is updated to Flutter 1.9 and also the plugins are updated to the latest version available.
