# flutter_secure_storage_darwin

This is the platform-specific implementation of `flutter_secure_storage` for iOS macOS.

## Features

- Secure storage using the Keychain API.
- Fully integrated with iOS and macOS security features.

## Installation

Add the dependency in your `pubspec.yaml` and run `flutter pub get`.

## Configuration

You also need to add Keychain Sharing as capability to your iOS or macOS runner. To achieve this, please add the following in *both* your `(ios/macos)/Runner/DebugProfile.entitlements` *and* `(ios/macos)/Runner/Release.entitlements`.

```
<key>keychain-access-groups</key>
<array/>
```

If you have set your application up to use App Groups then you will need to add the name of the App Group to the `keychain-access-groups` argument above. Failure to do so will result in values appearing to be written successfully but never actually being written at all. For example if your app has an App Group named "aoeu" then your value for above would instead read:

```
<key>keychain-access-groups</key>
<array>
	<string>$(AppIdentifierPrefix)aoeu</string>
</array>
```

If you are configuring this value through XCode then the string you set in the Keychain Sharing section would simply read "aoeu" with XCode appending the `$(AppIdentifierPrefix)` when it saves the configuration.

## Changelog
## 0.3.2
- Fixed `secStoreAvailabilitySink` not being called when protected data availability changes.
- Fixed `kSecUseDataProtectionKeychain` being added to Keychain queries unconditionally; it is now only set when `useDataProtectionKeychain` is explicitly enabled.

## 0.3.1
- Fixed iOS build by updating availability annotation for Secure Enclave methods from `iOS 11.3` to `iOS 13.0`.

## 0.3.0
- Added `useSecureEnclave` support for iOS and macOS to store encryption keys in the device's Secure Enclave for hardware-backed security.
- Use shared `LAContext` to reuse biometric authentication across Secure Enclave operations, avoiding double authentication prompts.
- Secure Enclave keys now use hardcoded `.privateKeyUsage` access control, preventing "ACL operation is not allowed" errors.

**Fixes:**
- Fixed `kSecAttrSynchronizable` being silently dropped when no access control flags are set.
- Fixed `readAll` to correctly return Secure Enclave items.
- Fixed macOS options keys alignment with iOS options.
- Added plain-text fallback when a Secure Enclave wrapped key is missing.

## 0.2.0
- Remove keys regardless of synchronizable state or accessibility constraints.

## 0.1.1
 - Fix warnings with Privacy Manifest

## 0.1.0
This package combines flutter_secure_storage_macos together with the ios part of flutter_secure_storage.

Other changes:
- Code has been rebuild from the ground up
- Lots of missing attributes have been added to the IOSOptions and MacOsOptions classes.
