in_app_purchase_utils

Flutter plugin for opening the system "manage subscriptions" UI on both iOS (StoreKit) and Android (Google Play).

Usage

import 'package:flutter/services.dart';
import 'package:in_app_purchase_utils/in_app_purchase_utils.dart';

final iap = InAppPurchaseUtils();

try {
  // Open the full subscriptions list.
  await iap.showManageSubscriptions();

  // Or, on Android, jump straight to a specific subscription product.
  await iap.showManageSubscriptions(sku: 'monthly_pro');
} on PlatformException catch (e) {
  debugPrint('Failed to open manage subscriptions: ${e.code} ${e.message}');
}

Behavior

iOS

• iOS 15+: presents the system manage-subscriptions sheet via AppStore.showManageSubscriptions(in: scene) on the active foreground UIWindowScene.
• iOS 13–14: opens https://apps.apple.com/account/subscriptions in Safari.
• The sku argument is ignored on iOS.

Possible error codes: NO_SCENE, STOREKIT_ERROR, INVALID_URL.

Android

Launches an ACTION_VIEW intent for the Play Store subscriptions deep link:

• No sku: https://play.google.com/store/account/subscriptions
• With sku: https://play.google.com/store/account/subscriptions?sku=<sku>&package=<applicationId>

Possible error codes: NO_HANDLER (no activity can resolve the intent — typically a device without Play Services), INTENT_ERROR.

Requirements

• iOS deployment target: 13.0
• Android minSdk: 24
• Flutter: 3.3.0+
