I have had the same issue, have managed to get it working using expo-dev-client.

I didn't find a way to fix this for Expo Go - not sure if there is one currently. It seems like using Oauth google login on IOS, currently requires building the app.

Once you configure the build, you can use

import { makeRedirectUri } from 'expo-auth-session';

to get the correct redirect URL.

const [request, response, promptAsync] = Google.useAuthRequest({
 clientId: 'xxxx',
 iosClientId:
        'xxxx',
 redirectUri: makeRedirectUri()});

Also remember to generate IOS credentials in the google console.

So it's possible to get the idToken if you that's all you are looking for. You need to modify your code like this:

     const [request, response, promptAsync] = Google.useAuthRequest({
        *responseType: "id_token",*
        expoClientId: 'my-expo-id',
        iosClientId: 'my-ios-id',
      });

You will also have to access the "params" key rather than "authentication," which will show mostly null :). For me it works at least since the rest of the information was useless. HTH!

Edit: I realized that I need to get an Access Token to use google drive in my app, and thus now I need both tokens and submitted a bug report here https://github.com/expo/expo/issues/12808 to try to get this resolved.

Try this:

-Login to your expo account: on command line type:

expo login
##then your account credencials##

then restart your expo instance:

expo start

And everything should work fine
