flutter_local_authentication 2.1.0

A flutter plugin that allows access to Local Authentication / Biometrics on iOS, macOS, Linux and Android.

2.1.0

• Add Windows Hello support for canAuthenticate, getAvailability, getBiometryType, authenticate and cancelAuthentication
• Windows uses the system-selected Windows Hello verifier and reports multiple for the biometry type because Windows does not expose the enrolled sensor through this API

2.0.0

• Add AuthenticationMethod (biometricsOnly, biometricsOrDeviceCredential, deviceCredentialOnly) as an optional method parameter of canAuthenticate and authenticate, on Android, iOS, macOS and Linux. Users without enrolled biometrics can authenticate with their device credential (thanks @tmpfs for the idea in #6)
• Unsupported methods make canAuthenticate return false, and authenticate fail with the unsupported_method error code
• Add getAvailability, that tells why the user can not authenticate (notEnrolled, lockedOut, credentialNotSet, notAvailable, unsupportedMethod)
• Add getBiometryType (face, fingerprint, iris, multiple, none)
• Add cancelAuthentication, to dismiss the prompt from the app
• authenticate throws an AuthenticationException (a PlatformException) with a reason that is the same on every platform: userCanceled, systemCanceled, lockedOut, notEnrolled, notAvailable, credentialNotSet, unsupportedMethod, failed
• iOS / macOS: add Swift Package Manager support, next to CocoaPods
• iOS / macOS: share one Swift implementation in the darwin folder
• Fix .pubignore, so build outputs are no longer included in the published package
• Android: accept any FragmentActivity as host, instead of requiring FlutterFragmentActivity. A plain FlutterActivity no longer crashes the app at startup: authenticate fails with a descriptive error, and the other methods work
• Behaviour change: the default method is biometricsOnly on every platform
  • macOS: authenticate no longer falls back to the user's password by default
  • Android: canAuthenticate no longer returns true when only a device credential is set, which made authenticate fail afterwards
• iOS / macOS: every authentication prompts the user. A previous successful authentication is not reused, except for the Touch ID allowable reuse duration
• Fix setLocalizationModel never completing on Android, iOS and macOS, and make it return a Future<void> so it can be awaited
• iOS / macOS: the cancel button uses the cancelButtonTitle of the localization model, and the fallback button is hidden when the method is biometricsOnly
• iOS / macOS: compiles with Swift 6 (language mode 6, strict concurrency)
• Builds against the latest toolchains: Android Gradle Plugin 9.1 / Gradle 9.3 / Kotlin 2.4 (compileSdk 36, Java 17), Xcode 27
• Migrates the Android plugin to built-in Kotlin
• Minimum Android SDK is now 24 (was 19)
• Minimum iOS version is now 15.0 (was 12.0)
• Minimum macOS version is now 12.0 (was 10.11)
• Requires:
  • sdk: '^3.12.0'
  • flutter: '>=3.44.0'

1.2.0

• Add GitHub actions for publishing releases to pub.dev automatically
• Downgraded Flutter SDK
• Requires:
  • sdk: '>=3.1.0 <4.0.0'
  • flutter: '3.0.0'

1.1.0

• Add a localization model for messages shown to the user

1.0.0

• Implemented 'setTouchIDAuthenticationAllowableReuseDuration' for iOS and macOS
• Implemented 'getTouchIDAuthenticationAllowableReuseDuration' for iOS and macOS
• touchIDAuthenticationAllowableReuseDuration defaults to 0 Docs
• Requires:
  • sdk: '>=3.1.3 <4.0.0'
• Minimun iOS version 12.0
• Improved documentation

0.0.3

• Implements 'authenticate' operation in all platforms

  1. Android using Biometrics API

  2. macOS and iOS using Local Authentication

     • macOS uses LAPolicy deviceOwnerAuthentication
     • iOS uses LAPolicy deviceOwnerAuthenticationWithBiometrics

  3. Linux using libfprint (fprintd-verify)

0.0.2

• Implements 'supports' operation on Android using Biometrics API

0.0.1

• Implements 'supports' operation on macOS
• Implements 'supports' operation on Linux
• Implements 'supports' operation on iOS
