Vyuh

Secure storage ​

Why this capability exists ​

Credentials need a different storage policy from display preferences. A separate capability lets the App select platform protection while features share a small interface.

How the pieces fit together

When to use it ​

Use a suitable platform adapter for sensitive values. Decide how logout clears retained credentials and which platforms your adapter supports.

Use it from a feature ​

The following fragment runs after plugin initialization, for example inside a feature’s initialization hook or a ready screen.

dart
import 'package:vyuh_core/vyuh_core.dart';

final storage = vyuh.getPlugin<SecureStoragePlugin>()!;
await storage.delete("account.session");

Choose the implementation ​

Configure the secureStorage named slot in PluginDescriptor at App startup. Features depend on SecureStoragePlugin; the App supplies an implementation or provider configuration. Use named slots for system capabilities rather than adding them to others.

The default InMemorySecureStoragePlugin neither encrypts nor persists values. The word secure describes the contract; protection is supplied by the selected adapter.

See SecureStoragePlugin API and plugin lifecycle.
