🔧 Quick Start #

Basic Usage #

import 'package:flutter_inapp_purchase/flutter_inapp_purchase.dart';

// Create instance
final iap = FlutterInappPurchase();

// Initialize connection
await iap.initConnection();

// Get products
final products = await iap.requestProducts(
  skus: ['product_id'],
  type: PurchaseType.inapp,
);

// Request purchase
await iap.requestPurchase(
  request: RequestPurchase(
    ios: RequestPurchaseIOS(sku: 'product_id'),

iOS Notes #

• This plugin uses the OpenIAP Apple native module via CocoaPods (openiap 1.1.9).
• After upgrading, run pod install in your iOS project (e.g., example/ios).
• Minimum iOS deployment target is 15.0 for StoreKit 2 support.

🛠️ Development #

• Install dependencies: flutter pub get
• Run lints: dart analyze
• Run tests: flutter test
• Enable Git hooks (recommended): git config core.hooksPath .githooks
  • The pre-commit hook auto-formats staged Dart files and fails if any file remains unformatted. It also runs tests.
  • To run tests in the hook, set RUN_PRECOMMIT_TESTS=1 in your environment.
  • To make analyzer failures block commits, set ENFORCE_ANALYZE=1.

Singleton Usage #

For global state management or when you need a shared instance:

// Use singleton instance
final iap = FlutterInappPurchase.instance;
await iap.initConnection();

// The instance is shared across your app
final sameIap = FlutterInappPurchase.instance; // Same instance
