❌ What Needs to be Built

1. Flutter UI Screens (Priority 1) 🚨

Create these 8 screens in flutter_app/lib/screens/:

1. predictions_screen.dart

   • Premium gate for free users
   • Show predictions for all 6 games
   • Display FR/SR numbers, analysis, confidence
   • Refresh functionality

2. dream_screen.dart

   • Premium gate
   • Language selector dropdown (Hindi, Bengali, English, etc.)
   • Text input for dream description
   • Submit button → Call API
   • Display results: symbols, numbers, analysis
   • Dream history list (past dreams)

3. subscribe_screen.dart

   • Hero section: "50% OFF - ₹29/month"
   • Features list with checkmarks
   • Razorpay payment button
   • Handle payment success/failure
   • Activate premium after payment

4. profile_screen.dart

   • User info (email if entered)
   • Premium status card:
     • If free: "Upgrade" button
     • If premium: "Active until [date]", "Manage" button
   • Settings: Notifications toggle, Language dropdown
   • About app, Logout

5. result_detail_screen.dart

   • Game name header
   • Today's FR/SR (large display)
   • Quick stats card
   • Past results table (7 or 30 days based on premium)
   • Premium upsell if free

6. common_numbers_screen.dart

   • Game selector dropdown
   • Hot numbers display (with frequency)
   • Cold numbers display
   • Day-wise analysis (premium only)

   • Calculate button
   • Results display with explanation

8. manage_subscription_screen.dart

   • Subscription details card
   • Next billing date
   • Amount
   • Cancel subscription button (with confirmation dialog)

2. Razorpay Integration (Priority 1) 🚨

In subscribe_screen.dart:

import 'package:razorpay_flutter/razorpay_flutter.dart';

// Initialize
late Razorpay _razorpay;

@override
void initState() {
  super.initState();
  _razorpay = Razorpay();
  _razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
  _razorpay.on(Razorpay.EVENT_PAYMENT_ERROR, _handlePaymentError);
}

// Open Razorpay checkout
void _openCheckout() async {
  // 1. Call API to create subscription
  final result = await ApiService.createSubscription(userId, email, planId);

  // 2. Open Razorpay
  var options = {
    'key': 'rzp_live_YOUR_KEY',
    'subscription_id': result['subscriptionId'],
    'name': 'Teer Khela Premium',
    'description': 'Monthly Subscription',
    'prefill': {'email': email},
  };
  _razorpay.open(options);
}

// Handle success
void _handlePaymentSuccess(PaymentSuccessResponse response) {
  // Update user premium status
  Provider.of<UserProvider>(context, listen: false).setPremium(true);
  // Show success dialog
  // Navigate to predictions
}

3. Firebase Notification Navigation (Priority 2)

In main.dart:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  await StorageService.init();
  await NotificationService.initialize();

  // Set notification tap handler
  NotificationService.onNotificationTap = (screen) {
    // Navigate based on screen
    navigatorKey.currentState?.pushNamed('/$screen');
  };

  runApp(MyApp());
}

// Add global navigator key
final GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();

// In MaterialApp:
MaterialApp(
  navigatorKey: navigatorKey,
  ...
)

4. React Admin Dashboard (Priority 3)

Create new project:

npm create vite@latest admin-dashboard -- --template react
cd admin-dashboard
npm install react-router-dom axios chart.js react-chartjs-2

Pages to create:

1. Login (/login)
2. Dashboard (/) - Stats, charts
3. Users (/users) - Table, filters, actions
4. Predictions (/predictions) - Override form
5. Notifications (/notifications) - Send form, history
6. Results (/results) - Manual entry
7. Analytics (/analytics) - Charts
8. Settings (/settings) - Config

All admin API calls require JWT:

axios.defaults.headers.common['Authorization'] = `Bearer ${token}`;
