auth_grace 0.0.4

Smart biometric auth with grace period. Skips prompt if phone was recently unlocked.

0.0.4

• Fix: README demo GIF now renders correctly on pub.dev.

0.0.3

• Fix: init() now always regenerates the Keystore key so changes to gracePeriodSeconds take effect immediately without requiring a reinstall.
• Fix: Grace period countdown is now driven by isWithinGracePeriod() polled every second — locks exactly when the Keystore expires, not based on a drifting Dart timer.
• Fix: gracePeriodActive (device-unlock grace) now shows the countdown timer in the example app.
• Example: Added circular countdown UI showing remaining grace window in seconds, turns orange at 2 seconds remaining.
• Example: Grace period timer auto-locks the UI when expired — no automatic re-prompt.

0.0.2

• Fix: Updated authenticate() call for local_auth 3.x API — AuthenticationOptions replaced with flat parameters (biometricOnly, persistAcrossBackgrounding).
• allowDeviceCredential: false now correctly maps to biometricOnly: true in the prompt.
• Added pub.dev topic tags: authentication, biometrics, security, local-auth.
• Raised minimum Dart SDK constraint to >=3.9.0 to align with flutter_lints ^6.0.0.
• Upgraded flutter_lints to ^6.0.0 — zero lint issues.
• Fix: LocalAuthException codes now map to correct AuthStatus instead of always returning AuthStatus.error.
  • noCredentialsSet, noBiometricsEnrolled, noBiometricHardware → AuthStatus.notAvailable.
  • userCanceled, timeout, systemCanceled, userRequestedFallback → AuthStatus.failed.
  • All other codes (lockout, device error, etc.) remain AuthStatus.error.
