I have to add local authentication to the flutter app. Found great solutions local_auth which is easy to integrate.
authenticated = await auth.authenticate(
localizedReason: 'Let OS determine authentication method',
useErrorDialogs: true,
stickyAuth: true,
biometricOnly: false,
);
Everything works cool, But the authentication asks only for fingerprint.
In my phone i have (face id, fingerprint, pattern) mostly i use pattern because Fingerprint works sometimes, sometimes not, maybe my phone was damaged or i don't know.
But i wanted to have an option to decide between pattern and fingerprint. Is it possible? if i turn off fingerprint then auth_local asks for pattern, and if it would be the end user, he won't get it, he simply won't be able to pass the authentication.
If it possible i would like to turn off biometric leaving only (pin,pattern,password) lite security, ideally to select between pattern or fingerprint.
Is there any solution, this makes to refuse from local_auth, Please Advice.
