Recent breakage of google-sign-in with flutter on Chrome?
Aha! The culprit here was blocking of third party cookies. If I turn off third party cookie blocking, things work fine.
Yikes, this makes using Google-sign-in unusable for webapps whose customers are blocking third party cookies.

As of 1 day ago, I seem to have trouble with google sign in running inside a flutter app on firebase.
When loading the webapp, I see an exception with obfuscated stack traces:
Uncaught TypeError: t.gpT is not a function at Im.$1 (google_sign_in_web.dart:113) at Object.a4P (js_helper.dart:1060) at Object.Yq (core_patch.dart:84) at a6F (js_patch.dart:541) at js_patch.dart:519 at e.zo (cb=gapi.loaded_0:200) at lk (cb=gapi.loaded_0:203) at gk (cb=gapi.loaded_0:203) at _.Rj.hU (cb=gapi.loaded_0:203) at Qj (cb=gapi.loaded_0:195)
This happens when deploying on firebase and on Chrome, not when running on localhost (same chrome), or when using the firebase deployment on Safari.
I'm properly stumped - I don't remember having upgraded the browser or changing anything in the code. Neither do I remember having fiddled with the oauth tokens.
Any ideas how to properly debug this ? I'm fairly inexperienced in dart/firebase/JS.
[Update]: I found that I can reproduce this even with the Google provided example at:
https://github.com/flutter/plugins/tree/master/packages/google_sign_in/google_sign_in/example
This works when I run it with
flutter run -d chrome
orflutter run -s web-server
When I do a
firebase deploy
, the app runs fine in Safari. In Chrome I get above exception. I tried to disable all extensions, same thing.-
helloWorld over 3 yearsExact same issue. Deployed on Firebase, works perfectly on Safari. Doesn't even show a pop-up on Chrome. Allowed all cookies, still the same.

https://github.com/funwithflutter/tutorials/tree/master/001-Flutter-Web-Firebase-Auth-Google
- third party cookies must be allowed :( -
helloWorld over 3 yearsI have allowed all cookies in my Chrome. Still the same issue. Works fine on Safari

Klapaucius Klapaucius over 3 yearsAre you sure you're having no chrome extensions set ? There may also be problems with same-site cookies (overridden via Chrome flags). The sign-in library seems fairly troubled, I just switched to usernames and passwords, for which firebase has support. Does your console give any useful errors other than this one?
