Breaking changes

items deprecated in v10 have been removed.
Any data saved using deprecated algorithms or features will be unusable after this upgrade. If you used a version prior to v10, upgrade to v10 first so existing data is migrated.

Android

• Removed KeyCipherAlgorithm.RSA_ECB_PKCS1Padding. Upgrade to v10 first so existing data is migrated to RSA_ECB_OAEPwithSHA_256andMGF1Padding before upgrading to v11.
• Removed StorageCipherAlgorithm.AES_CBC_PKCS7Padding. Upgrade to v10 first so existing data is migrated to AES_GCM_NoPadding before upgrading to v11.
• Removed encryptedSharedPreferences parameter from AndroidOptions and AndroidOptions.biometric. The Jetpack Security (EncryptedSharedPreferences) backend is no longer supported; any remaining data was automatically migrated to custom cipher storage in v10.
• Removed sharedPreferencesName from AndroidOptions. Use storageNamespace instead for full namespace isolation.
• Raised minSdk to 24 and compileSdk to 37. Flutter 3.35 raised its own Android minimum to API 24, making API 23 support unverifiable with any supported Flutter version. The legacy AES-CBC cipher path that supported API 21-22 has been removed.

Features

• android: add requireBiometricConfirmation option to AndroidOptions (7f5f7de)

Bug Fixes

• android: catch Throwable on worker thread so keystore Errors don't crash the app (d5802ff)
• android: don't swallow VM errors, catch Throwable on biometric thread too (d413d3f)
• linux: handle missing default keyring (b39c7c1)
• linux: fail closed on orphaned keyring data (2e720ff)
• remove redundant ./ prefix from part directives (cc7018d)
