Release notes
Breaking changes
- Android: minSdk raised from 16 to 18 (API 18 is the true minimum for AndroidKeyStore).
- Android: V1 plugin embedding (registerWith(Registrar)) removed.
- iOS: deployment target raised from 8.0 to 12.0.
Bug fixes
- Android: fix ANR caused by crypto initialisation blocking the main thread. All KeyStore and AES operations now run on Dispatchers.IO (fixes #57).
- Android: method calls that arrive before async init completes are queued and replayed once the crypto engine is ready.
- Android: get now returns null instead of throwing on BadPaddingException / InvalidKeyException, preventing crashes after key rotation or data corruption (fixes #37).
- iOS: fix CFDataRef memory leak in get: when SecItemCopyMatching returns a non-NULL reference on error.
New features
- Dart: new FlutterKeychain.configure({accessGroup, label}) method.
- iOS: accessGroup sets kSecAttrAccessGroup for shared keychain access between apps in the same App Group (fixes #48).
- iOS: label sets kSecAttrLabel so items appear in iOS Passwords (Settings → Passwords) (fixes #43).
- iOS: Swift Package Manager support added via ios/flutter_keychain/Package.swift (fixes #58). CocoaPods remains supported during the transition period.
Build / toolchain updates
- Android: AGP 7.1.2 → 8.3.2; namespace declaration is now unconditional (fixes #46, #41).
- Android: Kotlin 1.6.10 → 1.9.25.
- Android: compileSdk / targetSdk 31 → 35.
- Android: kotlinx-coroutines-android 1.7.3 added as a dependency.
