Flutter OAuth2 does not attach Google session to existing anonymous session

Hi Appwrite team,

I’m using Appwrite Auth in a Flutter mobile app and trying to upgrade an anonymous user to Google OAuth.

Docs say that if there is already an active session, a new OAuth2 session should be attached to the currently logged-in account. But in Flutter, createOAuth2Session() creates/logs in a different Google Auth user instead of attaching Google to the existing anonymous user.

Environment:

Flutter app Appwrite Flutter SDK 18.0.0 Platform: Android Provider: Google OAuth2 Flow:

Create anonymous session Complete onboarding From profile, call Google OAuth while anonymous session is still active Code:

`final before = await account.get(); final beforeSession = await account.getSession(sessionId: 'current');

await account.createOAuth2Session( provider: OAuthProvider.google, scopes: ['email', 'profile'], );

final after = await account.get(); final afterSession = await account.getSession(sessionId: 'current');` Logs:

`before userId=6a1735f10af0d84b8fe2 before provider=anonymous

after userId=6a1736370ef80119884d after provider=google

attachedToPreviousSession=false` Expected: after.$id should equal the anonymous user id.

Actual: Appwrite creates/logs in a different Google Auth user, so I end up with 2 Auth users: anonymous + Google.

Question: Is anonymous -> OAuth upgrade supported in Flutter/native via createOAuth2Session()
