Android 12 passkey authentication issue help

[udaychandra]

Hello,

Our flutter android app registration flow with passkeys is working fine but the login/authenticate flow is not working. Not sure how to debug this exception: PlatformException(android-no-credential, During begin sign in, failure response from one tap: 16: Cannot find a matching credential., , null)

Not sure why android can't find a matching credential when the registration was successful.

All configurations outlined here https://developer.android.com/training/sign-in/passkeys were followed. Not sure, what is missing. If it helps, the registration UI looks like this and the flow works fine.

When we logout and log back in using the authenticate flow, the error above is thrown.

Our flutter app is fully configured to support passkeys. Support for digital asset links has been added.

And thank you providing this excellent package to the community!

Closing this request. The problem was on out relying party implementation and differences b/w Apple and Android handling of authenticatorSelection.
