I don't have an iOS device with FaceID support but I checked this on my device with finger print: iPhone 7, iOS 15.8. I can see NotAvailable code in the 3rd case on my end.

3rd case: not recognized case (tap Cancel button when authenticating with wrong finger):

flutter: PlatformException(NotAvailable, Authentication canceled., com.apple.LocalAuthentication, null)

2nd case: too many wrong attempts:
(No error is printed)

I also checked a case by turning off passcode (Settings > Touch ID & Passcode > Turn Passcode Off) and saw the expected code outputs:

flutter: PlatformException(PasscodeNotSet, Passcode is not set., com.apple.LocalAuthentication, null)

I see there was an issue that looks similar to this at #102734 . And it seems to check if Apple's API can return separate error codes for such these case above or not. Maybe NotAvailable error code in the 3rd case is an intended code from Apple's API.

Labeling this for other's insights. This may also relate to #113687 as well.
