Getting Started

1. Initialize the SDK

Initialize AppNinja during app startup with your API key:

import 'package:in_app_ninja/in_app_ninja.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  
  AppNinja.init(
    'YOUR_API_KEY',
    autoRender: true,
  );
  
  runApp(const MyApp());
}

2. Identify Users

Set user properties for personalized targeting:

await AppNinja.userIdentifier(
  externalId: 'user_123',
  name: 'John Doe',
  email: 'john.doe@example.com',
  userProperties: {
    'subscription': 'premium',
    'sign_up_date': '2026-06-25',
  },
);

3. Track Events

Track actions to trigger campaigns dynamically:

await AppNinja.track('add_to_cart', properties: {
  'item_id': 'prod_99',
  'category': 'footwear',
});

4. Track Pages

Track current screen changes to target page-specific nudges:

AppNinja.trackPage('checkout_screen', context);
