qbox_authorization 1.0.2

A simple Flutter authentication package with login screen and provider support.

QBox Authorization

QBox Authorization provides a complete workspace-aware authentication flow for Flutter apps. It ships a domain selection screen, branded login UI that is configured from your backend /appearance endpoint, and the provider-powered state management needed to obtain an auth token in only a few lines of code.

🚀 What’s inside

• Workspace picker that validates a company domain before showing the login form.
• Remote theming via the /appearance endpoint (icon, title, background, description).
• Localized UI (1: Russian, 2: Kazakh, 3: English) with runtime switching through localeId.
• Token-based login handled by AuthProvider and returned through the onSuccess callback.
• Optional TestLogin helper for QA/demo presets and built-in loading/error handling.

📦 Installation

⚙️ Getting started

1. Register AuthProvider

void main() {
  runApp(
    MultiProvider(
      providers: [
        ChangeNotifierProvider(create: (_) => AuthProvider()),
      ],
      child: const MyApp(),
    ),
  );
}

AuthProvider owns the login controllers, visibility state, token fetching, and /appearance cache, so it must live above the widgets that use AuthFlow or AuthScreen.

2. Drop in the full flow

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  void _handleSuccess(BuildContext context, String token, String baseUrl) {
    // Persist the token or navigate to the rest of your app.
    Navigator.push(context, MaterialPageRoute(builder: (_) => const HomeScreen()));
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Builder(
        builder: (context) {
          return AuthFlow(
            localeId: 1, // 1=ru, 2=kk, 3=en
            onSuccess: (token, baseUrl) => _handleSuccess(context, token, baseUrl),
          );
        },
      ),
    );
  }
}

AuthFlow first renders the company selection screen where the user types their domain (e.g., qbox.company.kz). Once the package validates the domain by calling https://{domain}/appearance?locale_id=..., it automatically transitions to the branded login UI and finally invokes onSuccess(token, baseUrl) when authentication completes.

3. Need to jump straight to the login screen?

If you already know the tenant base URL (for example, you store it with the user profile), you can bypass the domain step and use AuthScreen directly:

AuthScreen(
  baseUrl: 'https://qbox.company.kz',
  localeId: 2,
  testLogin: const TestLogin(username: 'demo', password: 'secret123'), // optional
  onSuccess: (token, baseUrl) {
    // Handle the token.
  },
);

Use the optional testLogin to pre-fill credentials in QA builds. When omitted, users interact with the regular text fields.

🌐 Localization reference

localeId	Language
1	Russian (ru) – default
2	Kazakh (kk)
3	English (en)

The same localeId is passed to both the domain discovery screen and the /appearance request, so your backend can serve localized branding assets and strings.

🧪 Example project

Check example/lib/main.dart for a runnable Flutter app that wires the provider, launch flow, and a dummy HomeScreen. Use it as a quick sanity check after integrating the package.
