Flutter Keychain Access Plugin

A Flutter plugin that provides keychain access for securely storing and retrieving data on iOS. It also allows data sharing between apps using the same app group identifier.


  • Securely store data in the iOS keychain.
  • Retrieve stored data from the keychain.
  • Share data between multiple apps using a common app group identifier.


To use this plugin, add apple_keychain as a dependency in your pubspec.yaml file:

  apple_keychain: ^1.0.0

Then, import the library into your Dart code:

import 'package:apple_keychain/apple_keychain.dart';

Storing Data

To store data in the keychain, use the write method:

String key = 'myKey';
String value = 'myValue';
await AppleKeychain.write(key: key, value: value);

Retrieving Data

To retrieve data from the keychain, use the read method:

String key = 'myKey';
String value = await AppleKeychain.read(key: key);

Sharing Data Between Apps

To share data between multiple apps using the same app group identifier, set the accessGroup parameter when reading or writing data:

String key = 'myKey';
String value = 'myValue';
String accessGroup = 'com.example.appgroup';
await AppleKeychain.write(key: key, value: value, accessGroup: accessGroup);

String sharedValue = await AppleKeychain.read(key: key, accessGroup: accessGroup);

Make sure to configure the appropriate app group identifier in your Xcode project settings.
