webauthn_secure_storage_darwin 0.2.1

iOS and macOS implementation of the webauthn_secure_storage federated plugin.

Changelog

0.2.1

• Fix the macOS plugin lifecycle so BiometricStorageImpl persists across method calls, preserving initialized secure-storage instances for later reads, writes, deletes, and existence checks.

0.2.0

• Rebrand the federated plugin family from biometric_storage to webauthn_secure_storage across packages, folders, imports, docs, and platform metadata.
• Reset the fork changelog so future changes are tracked independently.
• Clean generated artifacts from the repository and refresh ignore rules for a cleaner Flutter package workspace.
• Clarify the recommended app integration workflow in the package README, including the distinction between platform support and biometric availability-at-runtime.
• Document platform-specific project setup requirements for Android, iOS, macOS, Linux, Windows, and web consumers.
• Improve Darwin biometric availability handling for macOS closed-clamshell and similar temporarily-unavailable authenticator states.
• Replace deprecated macOS Keychain prompt/UI query usage with modern LAContext-based configuration.

Data-migration note for Linux users

The libsecret schema name for new writes is now "dev.webauthn_secure_storage". To preserve upgrade compatibility, reads, existence checks, and deletes also fall back to the upstream schema "design.codeux.BiometricStorage" and the legacy key prefix when needed.

Existing Linux secrets remain readable after upgrade. They will continue to use the legacy schema until they are re-written with this package.

Data-migration note for Apple platforms

New writes now use the keychain service "flutter_webauthn_secure_storage". To preserve upgrade compatibility, reads, existence checks, and deletes also fall back to the upstream keychain service "flutter_biometric_storage" when needed.

Existing iOS and macOS secrets remain readable after upgrade. They will move to the new service only after being re-written with this package.
