biometric_auth_lock 0.3.1

A reusable biometric authentication and PIN lock service for Flutter apps with support for fingerprint, Face ID, and PIN fallback

Changelog

0.3.1

• Fixed LocalAuthService.setupBiometric (and the biometric-not-supported branch of resolveWithBiometric) overwriting the persisted BiometricAuthData with a fresh object instead of copyWith-ing the existing one — this silently wiped the fallback PIN (and lastAuthenticated) whenever a user enabled/accepted biometric authentication after having already set a PIN.

0.3.0

• Added getPinCodeAfterBiometricAuth to ILocalAuthService / LocalAuthService — reveals the stored PIN fallback after a successful biometric check, throwing BiometricAuthPinNotConfiguredException or BiometricAuthPinFailedException when it can't.
• Added BiometricLockService.getPinAfterBiometricAuth(...) facade method — same behavior, returns null instead of throwing.
• Added new exception types (BiometricPinAuthException and subclasses), now exported from the package root.
• analysis_options.yaml now excludes generated platform folders (android/, ios/, build/, etc.) from analysis.

0.2.1

• Add french documentation

0.2.0

• Breaking: BiometricLockService.withDefaults(LocalStorage) renamed to BiometricLockService.withStorage(LocalStorage).
• Added parameterless BiometricLockService.withDefaults() — creates its own SharedPreferencesLocalStorage internally. Consumers no longer need to import local_storage_impl for the common case.
• Added storage backend documentation (SecureLocalStorage, SharedPreferencesLocalStorage, MapLocalStorage) with usage examples.
• Restructured Platform Setup: moved FlutterFragmentActivity requirement from Troubleshooting into the Android setup section.
• Fixed README code samples that attempted to instantiate the abstract LocalStorage class directly.
