So I already following steps in here, but when I try to run it. It doesn't show anything and there's no error message. I try without firebase code on gradle since I think it causing that (because build.gradle in video and firebase website is different), and it still same no app and no error message Edit : I manage to run the app, the problem is when I press Google button it doesn't showing anything

7:12 line number 28, the authentication shows this error. The getter 'authentication' isn't defined for the type 'GoogleSignInAuthentication'. (Documentation) Try importing the library that defines 'authentication', correcting the name to the name of an existing getter, or defining a getter or field named 'authentication'.

[@dbestech]

[@rustyrishii]

hey, for me, it isnt asking to choose the account after i signout, It directly logs me back in with my previous account! what could be wrong?

[@dbestech]

Then you need to delcare final GoogleSignInAccount? googleUser = await GoogleSignIn( scopes: ["email"]).signIn(); globally and call googleUser.signOut() from the sign out method. see in the link description

[@dbestech]

This kind of tutorial would be very very long.

[@Raggii]

Hello I followed through everything and it was very helpful although I was completing it on a web application! I got to the final step however and when I clicked to authenticate an error occurs mentioning that the client ID is not set. I was wondering if u had any insight into this. (ClientID not set Either set it on a tag, or pass clientId when initializing GoogleSignIn")

[@dbestech]

It was for app, not for website. that's why you get this error.

[@TheAbhidugar]

Awesome bro. It's crystal clear.

[@dbestech]

Thanks a lot. Thanks for the support all the time.

[@ivantrejo8428]

What about Flutter Fire? all the docs seem to pointing the user to FlutterFire CLI. Can you make a video with that method? or is there any significant difference?

[@dbestech]

I think both can work. I will make a tutorial about it.

Thank you for your video. When i logged in with my google account, the login page shows up again not the home page. There is an error that says Null check operator used on a null value

[@dbestech]

check your google data returned from firebase. it should be the credential variable.

Hi I did the exact steps but got an error that The following _CastError was thrown building HomeScreen(dirty, dependencies: [MediaQuery], state: _HomeScreenState#dc875): Null check operator used on a null value Any idea how to fix this?

Make sure all the packages and libraries are imported and then do flutter clean and try again. If it still does not work then delete app and try again
