'Couldn't sign you in' popup on Google sign in

[Shamik07]

I have the same issue open on the Flutter Fire desktop package... I thought this was a problem specific to the FlutterFire desktop package, but today I Ran the example app (flutter_desktop_webview_auth) (Windows 10), it runs perfectly, When I try the Google Sign In option the pop asking me for the email or phone number pops up but when I enter my email and try to sign in I get a
Couldn't sign you in... This browser or app may not be secure. Window

What's the current Edge version you're running on?

Version 100.0.1185.29 (Official build) (64-bit)

The issue here is that Google is rejecting the WebView2, see here.

I'm not sure why it works on some devices. I'll update you soon if I could find a workaround.

@Shamik07 could you please try running the example app on the current main branch? let me know if you're still facing the same issue.

The same error for me (desktop_webview_auth: ^0.0.6 in pubspec.yaml)

Whan I clone flutter_desktop_webview_auth repo and use dependency override for main branch, everything is OK:

dependency_overrides:
  desktop_webview_auth:
    path: d:/github/flutter_desktop_webview_auth

Hey @PavelPZ, you could sign in with Google when you used the main branch?

[PavelPZ]

Yes, main branch is working for me.
Is it possible to update the pub.dev package?

Amazing, sure! will push an update soon, thanks for confirming.
