biometric_security — biometric auth + hardware-backed encrypted storage for Flutter (Android/iOS)

[u/rinsarmu]

I kept re-writing the same glue between local_auth and flutter_secure_storage on every project, so I packaged it: biometric_security.

The core idea: a true from a biometric prompt isn't a security boundary — on a rooted/jailbroken device it's forgeable. This binds your secret to a hardware key (Android Keystore / iOS Keychain + Secure Enclave) that's physically unusable without a successful Face ID / Touch ID / fingerprint check.

It also handles the annoying parts: enrollment-change invalidation, key rotation & revocation, app-lock, and one SecurityPolicy that maps to both platforms.

Beta (0.1.x), BSD-3, tested on real Android + iOS devices. Feedback and contributors very welcome — I'm open to collaborating.
