## ⚡ Quick Start

### 1. Add Dependency

```yaml
# pubspec.yaml
dependencies:
  onairos:
    path: ../onairos-flutter # Local development
```

### 2. Basic Usage

```dart
import 'package:onairos/screens/npm_modal_flow.dart';

// Show complete Onairos flow
showDialog(
  context: context,
  barrierDismissible: false,
  builder: (context) => Dialog.fullscreen(
    child: NmpModalFlow(
      visible: true,
      onClose: () => Navigator.pop(context),
      onResolved: (apiUrl, token, userData) {
        // Handle completion
        print('User data: $userData');
      },
    ),
  ),
);
```

## 🎯 Design System

### Color Palette

```dart
// lib/theme/npm_colors.dart
class NpmColors {
  // Buttons
  static const Color btnGradStart = Color(0xFF1A1A1A);
  static const Color btnGradEnd = Color(0xFF000000);
  static const Color btnLabel = Color(0xFFFFFFFF);

  // Text
  static const Color textPrimary = Color(0xFF1A1A1A);
  static const Color textSecondary = Color(0xFF6B7280);
  static const Color textMuted = Color(0xFF9CA3AF);

  // Backgrounds
  static const Color background = Color(0xFFFFFFFF);
  static const Color backgroundSecondary = Color(0xFFF8F9FA);

  // Status Colors
  static const Color success = Color(0xFF10B981);
  static const Color error = Color(0xFFEF4444);
}
```

### Typography Scale

```dart
// Headers
TextStyle(fontSize: 24, fontWeight: FontWeight.bold)  // h1
TextStyle(fontSize: 20, fontWeight: FontWeight.bold)  // h2

// Body Text
TextStyle(fontSize: 16, fontWeight: FontWeight.normal) // body
TextStyle(fontSize: 14, fontWeight: FontWeight.normal) // small
```

### Button Component

```dart
// lib/components/ui/npm_primary_button.dart
NmpPrimaryButton(
  label: 'Continue',
  onPressed: () => handleAction(),
  iconRight: Icon(Icons.arrow_forward_ios),
  loading: false,
  disabled: false,
)
```

---

## 🔄 Modal Flow

### Flow Logic

```
New User Path:
Welcome → Email → Universal Onboarding → PIN → Loading → Data Request

Existing User Path:
Welcome → Email → Data Request

Back Navigation:
Each step ← Previous step (with state preservation)
```

### State Management

```dart
// Central flow manager
class NpmModalFlow extends StatefulWidget {
  final bool visible;
  final VoidCallback onClose;
  final String? appName;
  final Function(String apiUrl, String token, dynamic userData)? onResolved;
}

// Flow states
String _currentFlow = 'welcome'; // welcome | emailAuth | universalOnboarding | pinSetup | loading | dataRequest
Map<String, dynamic> _userData = {}; // Accumulated user data
```

---

## 🛠️ Implementation

### Modal Specifications

```dart
// Modal sizing (matching NPM exactly)
Container(
  width: 512,           // max-w-lg
  height: vh * 0.90,    // 90vh
  decoration: BoxDecoration(
    color: Colors.white,
    borderRadius: BorderRadius.circular(24),
  ),
)
```

### Universal Onboarding Layout

```dart
// Complex overlapping system
Stack(
  children: [
    // Background: Persona image
    Transform.translate(
      offset: Offset(0, -100), // Perfect positioning
      child: Image.network(personaUrl),
    ),

    // Foreground: Platform icons
    Positioned(bottom: 260, child: IconRow()),

    // Foreground: Info box
    Positioned(bottom: 120, child: InfoSheet()),

    // Footer: Action buttons
    Positioned(bottom: 16, child: ButtonRow()),
  ],
)
```

### OAuth Simulation

```dart
Future<void> _connectToPlatform(String name) async {
  setState(() => _isConnecting = true);

  // Simulate OAuth flow
  await Future.delayed(Duration(seconds: 2));
  print('🔗 OAuth would open here for $name');

  setState(() {
    _connectedAccounts[name] = true;
    _isConnecting = false;
  });

  HapticFeedback.mediumImpact();
}
```

## 🧪 Testing

### Local Development Setup

```bash
# 1. Create test app
flutter create onairos_test_app
cd onairos_test_app

# 2. Add local dependency
# pubspec.yaml:
dependencies:
  onairos:
    path: ../onairos-flutter

# 3. Test implementation
flutter run -d chrome
```

### Test Implementation

```dart
// lib/main.dart
import 'package:onairos/screens/npm_modal_flow.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: ElevatedButton(
            onPressed: () => _showOnairosFlow(context),
            child: Text('Open Onairos Flow'),
          ),
        ),
      ),
    );
  }

  void _showOnairosFlow(BuildContext context) {
    showDialog(
      context: context,
      barrierDismissible: false,
      builder: (context) => Dialog.fullscreen(
        child: NmpModalFlow(
          visible: true,
          onClose: () => Navigator.pop(context),
          appName: 'Test App',
          onResolved: (apiUrl, token, userData) {
            Navigator.pop(context);
            print('✅ Flow completed: $userData');
          },
        ),
      ),
    );
  }
}
```

## 📚 API Reference

### NmpModalFlow

```dart
NmpModalFlow({
  required bool visible,           // Show/hide modal
  required VoidCallback onClose,   // Close handler
  String? appName,                 // App name for API calls
  Function(String, String, dynamic)? onResolved,  // Completion handler
})
```

### Individual Components

```dart
// Welcome Screen
NmpWelcomeScreen({
  required VoidCallback onContinue,
  required VoidCallback onClose,
})

// Email Auth
NmpEmailAuth({
  required Function(Map<String, dynamic>) onSuccess,
  bool testMode = true,
})

// Universal Onboarding
NmpUniversalOnboarding({
  required Function(Map<String, dynamic>) onComplete,
})

// PIN Setup
NmpPinSetup({
  required Function(Map<String, dynamic>) onComplete,
  VoidCallback? onBack,
  String? userEmail,
})

// Data Request
NmpDataRequest({
  String userEmail = 'user@example.com',
  bool testMode = true,
  required Function(Map<String, dynamic>) onComplete,
  bool autoFetch = true,
  String appName = 'Test App',
})
```

### Completion Data Structure

```dart
// Final onResolved callback receives:
{
  'apiUrl': 'https://api2.onairos.uk/inferenceTest',
  'userHash': 'user_abc123',
  'userData': {
    'email': 'user@example.com',
    'connectedAccounts': ['Google', 'Reddit'],
    'totalConnections': 2,
    'pin': '******',
    'approvedData': ['basic', 'personality'],
    'apiResponse': { /* AI personality data */ },
  }
}
```
