Secure storage

FlutterSecureStoragePlugin implements the core SecureStoragePlugin contract using flutter_secure_storage. Features can share this capability without depending on its platform adapter.

How the pieces fit together

Configure the capability

This configuration fragment goes in your app's vc.runApp call:

import 'package:vyuh_core/vyuh_core.dart' as vc;
import 'package:vyuh_plugin_storage_secure/vyuh_plugin_storage_secure.dart';

final plugins = vc.PluginDescriptor(
  secureStorage: FlutterSecureStoragePlugin(),
);

After platform initialization, retrieve the configured contract:

final storage = vc.vyuh.getPlugin<vc.SecureStoragePlugin>()!;
await storage.write('auth_token', 'example-token');
final token = await storage.read('auth_token');
final exists = await storage.has('auth_token');
await storage.delete('auth_token');

Reads return strings. Writes convert non-null values with toString(); writing null deletes the key. Encode structured data explicitly before storing it.

Platform requirements and options depend on the installed flutter_secure_storage version. Apply its setup instructions for each target before using the plugin.
