0.0.5 - 2026-03-21

Added

• WebAuthn Large Blob Extension: Support for storing and retrieving up to 1KB of opaque data directly on the passkey authenticator hardware across iOS 17+ and Android.
• Comprehensive JSON parsing support and unit tests for the largeBlob WebAuthn extension.

0.0.4 - 2026-03-21

Added

• Included hints, attestationFormats, and extensions to WebAuthn creation underlying parameters for robust JSON mapping.
• Implemented clientExtensionResults support within authentication response payloads.
• WebAuthn PRF (Key Encryption Key) extension support across iOS 18+ and Android Credential Manager, allowing extraction of symmetric keys from deterministic PRF salts directly during authentication.
• Added enablePrf parameter directly to createRegistrationOptions for enabling PRF evaluation during passkey registrations.
• Added PRF KEK Extraction Example directly inside the example application's UI demonstrating symmetric key derivation.

Changed

• Standardized and completely overhauled README.md to remove duplicated guides, ensuring much clearer setup instructions for both iOS and Android.
• Expanded the Dart unit test suite extensively to verify missing field defaults and string JSON edge cases natively.

Fixed

• Migrated explicitly nullable fields (userHandle, authenticatorAttachment, publicKey, etc.) in messages.dart to fully align natively with the permissive WebAuthn standard and prevent FIDO hardware decoder issues.
