FlutterSecureStorageAdapter class final

A KeyValueStoreInterface implementation backed by FlutterSecureStorage.

Provides secure, encrypted key-value storage suitable for storing sensitive data such as tokens, credentials, or secrets.

  • On Android, uses AndroidOptions with encryptedSharedPreferences enabled for maximum security.
  • On iOS, relies on the Keychain for secure storage.

Example:

final storage = FlutterSecureStorageAdapter();
await storage.write('token', 'abc123');
final token = await storage.read('token');
