Google Auth Access blocked: authorization error

I'm trying to add google auth to my flutter app but I'm facing this error and I'm not able to find the solution anywhere

I don't think there is any problem with the code since it is redirecting to this page but maybe with Google Console

Google requiring you o provide a top private domain when using OAuth.

The best solution in your case would be to create some host for your IP
Then add it to your Google OAuth consent screen.

And using mobile phone can make it a bit tricky if you're using you local environment.
There are few solution but each is more complex the the previous one.

From what I can see your best option would be:

1. Move it to some online server with Domain.
2. Use Cloudflare tunnel for free and point an outside real domain to your local instance of Appwrite
