Authentication Module

The template includes a complete authentication system with secure credential storage and error handling.

How it works

• Login & Registration: Uses Dio to POST to /api/login and /api/register endpoints.
• Credential Caching: Credentials are securely cached in Hive CE using AES-256 encryption, with key derived per-device.
• State Management: All authentication UI and logic is managed via Riverpod notifiers and state classes.
• Error Handling: All network and validation errors are surfaced in the UI.
• Loading State: UI reflects loading and error states for a smooth UX.

Test Credentials

You can test the authentication functionality using these credentials from reqres.in:

Login:

{
    "email": "eve.holt@reqres.in",
    "password": "cityslicka"
}

Register:

{
    "email": "eve.holt@reqres.in",
    "password": "pistol"
}

Example:

@riverpod
class LoginController extends _$LoginController {
  // ... state and logic here
  Future<LoginResponse> login({required String email, required String password}) async {
    // Handles login, error handling, caching, loading state etc.
  }
}
