What is flutter_inapp_purchase?​

This is an In App Purchase plugin for Flutter. This project has been forked from react-native-iap. We are trying to share same experience of in-app-purchase in flutter as in react-native.

We will keep working on it as time goes by just like we did in react-native-iap.

What this plugin does​

  • Product Management: Fetch and manage consumable and non-consumable products
  • Purchase Flow: Handle complete purchase workflows with proper error handling
  • Subscription Support: Full subscription lifecycle management
  • Receipt Validation: Validate purchases on both platforms
  • Store Communication: Direct communication with App Store and Google Play
  • Error Recovery: Comprehensive error handling and recovery mechanisms

Quick Start​

Get started with flutter_inapp_purchase in minutes:

flutter pub add flutter_inapp_purchase:^6.8.0
import 'package:flutter_inapp_purchase/flutter_inapp_purchase.dart';

// Initialize connection
await FlutterInappPurchase.instance.initConnection();

// Fetch product details
final result = await FlutterInappPurchase.instance.fetchProducts(
  ProductRequest(
    skus: ['product_id'],
    type: ProductQueryType.InApp,
  ),
);

final products = result.value;

// Request purchase
final requestProps = RequestPurchaseProps.inApp(
  request: RequestPurchasePropsByPlatforms(
    ios: RequestPurchaseIosProps(
      sku: 'product_id',
      quantity: 1,
    ),
    android: RequestPurchaseAndroidProps(
      skus: ['product_id'],
    ),
  ),
);

await FlutterInappPurchase.instance.requestPurchase(requestProps);

// Restore active purchases (include expired iOS receipts if needed)
final purchases = await FlutterInappPurchase.instance.getAvailablePurchases(
  PurchaseOptions(
    onlyIncludeActiveItemsIOS: true,
  ),
);

Sponsors & Community Support​

We’re building the OpenIAP ecosystem—defining the spec at openiap.dev, maintaining openiap-gql for the shared type system, and shipping native SDKs such as openiap-apple and openiap-google. These modules power expo-iap, flutter_inapp_purchase, kmp-iap, and react-native-iap. After simplifying fragmented APIs, the next milestone is a streamlined purchase flow: initConnection → fetchProducts → requestPurchase → (server receipt validation) → finishTransaction.

Your sponsorship keeps this work moving—ensuring more developers across platforms, OS, and frameworks can implement IAPs without headaches while we expand to additional plugins and payment systems. Sponsors receive shout-outs in each release and, depending on tier, can request tailored support. If you’re interested—or have rollout feedback to share—you can view sponsorship options at openiap.dev/sponsors.
