To: pve-devel; +Cc: haque
proxmox_login_manager's OpenID login flow (see the corresponding
patch there) opens the provider's authorization URL via
flutter_web_auth_2 and expects the provider's redirect back to
pveauth://openid-callback to be captured by the app. On Android this
requires explicitly registering flutter_web_auth_2's CallbackActivity
for that scheme; add it, following the plugin's setup instructions.
Also set android:taskAffinity="" on both activities as recommended
for this flutter_web_auth_2 version, to avoid a stray task appearing
after the callback returns control to MainActivity.
No changes needed on iOS: ASWebAuthenticationSession handles the
custom-scheme redirect without any Info.plist registration.
linux/flutter/generated_plugin_registrant.cc, generated_plugins.cmake
and pubspec.lock are regenerated as a consequence of the new
transitive dependency on flutter_web_auth_2 (and, on Linux/Windows,
its desktop_webview_window fallback).

Hi Azharul,
Thank you so much for your patches. If you are sending patches for the
first time and haven't yet had the chance to fill out our CLA. Please
check this: https://proxmox.com/en/about/open-source/developers
Right now, AFAICT, you have sent series for each repository seperately:
- android: register OpenID Connect callback activity for #4281 (pve_flutter_frontend)
- ui: implement OpenID Connect login flow for #4281 (proxmox_login_manager)
- add OpenID Connect support for #4281 (proxmox_dart_api_client)
Instead of sending the changes seperately as different series. Please
send them as a single series including the repository name inside the patch
subject prefix [0]. It would be really helpful for us when testing and
reviewing the changes. Thus reducing the noise on mailling list as well.
