Add Google Sign In

[Saransh-cpp]

Description

I think the Google Sign In has been implemented but has not been added to the frontend. Add it to the Register and Log In screen with all the necessary data. Adding this as hard as this will require passing the data in between files or initializing dummy data.

I have written the code but the googleSignIn() function in auth.dart keeps giving me the same error. Error => PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null) The error occurs on the second line of this function. I have searched about the error and keeps getting the same answer that there is some problem with firebase authentication. Here is a link to a stackoverflow answer I referred to -> https://stackoverflow.com/questions/54557479/flutter-and-google-sign-in-plugin-platformexceptionsign-in-failed-com-google I have checked the firebase. The chapter-3 app does have a sha1 key but the chapter3-admin does not. Is it possible that might be causing the error?

While working on the issue, I found another issue. On the home screen, the SingleChildScrollView widget is giving out an error. Can I raise this issue?

[Saransh-cpp]

Pointed out in #39

[Saransh-cpp]

I'll have a look at the error today

[mortal-ghost]

Thank you. I found another issue in the app. When you login with invalid credentials, the app logs in anyway with errors. Please take a look at this one too.

Can you create a new issue with some screenshots or more details?

[mortal-ghost]

Yes I will
