Start Coding in Minutes
Implement in-app purchases in your Flutter app with just a few simple steps. No complex native code required—just clean Dart async/await patterns.
1. Initialize the SDK
Start by initializing IAPHUB with your app credentials. This should be done when your app launches.
await Iaphub.start(
appId: "YOUR_APP_ID",
apiKey: "YOUR_API_KEY"
);2. Get Available Products
Retrieve the list of in-app products configured in your IAPHUB dashboard.
var products = await Iaphub.getProductsForSale();
for (var product in products) {
print('${product.title}: ${product.price}');
}3. Purchase a Product
Process a purchase with built-in error handling. IAPHUB handles all the complexity of StoreKit and Play Billing.
try {
var transaction = await Iaphub.buy("pack_10_coins");
print("Purchase successful!");
} catch (err) {
print("Purchase failed: $err");
}Why Not Just Use in_app_purchase?
While in_app_purchase is Flutter's official package that provides basic communication with StoreKit and Google Play Billing, it leaves many critical challenges unaddressed that you'll need to solve yourself.
No Server-Side Infrastructure
You'll need to build and maintain your own server for receipt validation, subscription management, and webhook processing.
Manual Receipt Validation
You must implement complex receipt validation logic for both App Store and Play Store, handling different receipt formats and edge cases.
Limited Subscription Management
No built-in handling of subscription states, renewal tracking, and grace periods.
No Analytics Dashboard
You'll need to build your own analytics system to track purchases, revenue, and subscription metrics.
Complex Error Recovery
You must implement your own logic for handling failed purchases, interrupted transactions, and receipt refresh failures.
No Fraud Prevention
You'll need to build your own system to detect and prevent common types of in-app purchase fraud.
IAPHUB provides all these features out of the box, along with a production-ready server infrastructure and comprehensive dashboard. Instead of spending months building these systems yourself, you can integrate our complete solution in just a few minutes.
