Device Pin/Pattern fallback?

[cking24343]

Hey all, simple question, forgive me if it's obvious but I'm new to biometrics in general. I was looking over the repo and wondering (mainly because I'm not seeing it), if there is support for allowing the user to fallback to using the device pin / pattern / password for use cases where they cancel out the biometric prompt?

The only thing I've found so far is a call where it looks like this has been explicitly disabled? I'm guessing this is intentional and the support for allowing a fallback for a user to cancel biometrics in lieu of device pin / pattern / password is not supported?

Hi.
Sorry for the delay with the answer :(
In general, I didn't expect that fallback would be needed, cause (for me) the main idea of this library - just "pure" biometric authentification.
But, is not a big deal to add CREDENTIALS (pin/pattern/etc) fallback to the current implementation.
I'll schedule this improvement for the next release

So, I'm on the final stage with implementation for DeviceCredentials feature.
Stay tuned, new release will be published soon

Fix available in 2.2.15 version.
Please note - due to the OS/vendor fragmentation, the current implementation may behave a bit differently from "native" BiometricPrompt.
Device Credentials will be used if target biometric cannt be used, but not simultaneously with biometric - that's mean OR biometric OR device credentials, but not together
