in_app_purchases using flutter

Question

I am trying to create an application that can handle In App Purchases Using Flutter.I am using the in_app_purchase 0.2.1 plugin .I have managed to setup my product on google play developer console as required but however when try to retrieve it from the application i am able to connect to the store successfully but i am not able to retrieve my product ,it always shows up as product not found.

I have followed a this tutorial https://joebirch.co/2019/05/31/adding-in-app-purchases-to-flutter-apps/ and also looked at the package documentation https://pub.dev/packages/in_app_purchase. My google play setup for the product is shown below google play console setup google play console setup2

The function i am using is shown below.

  Future<List<ProductDetails>> retrieveProducts() async {
final bool available = await InAppPurchaseConnection.instance.isAvailable();
if (!available) {
  // Handle store not available
  print("Store Temporarily Unavailable");
  return null;
} else {
  print("Store Temporarily Available");
  const Set<String> _kIds = {'airtime123'};
  final ProductDetailsResponse response =
      await InAppPurchaseConnection.instance.queryProductDetails(_kIds);
  if (response.notFoundIDs.isNotEmpty) {
    print("product not found");
    print(response.notFoundIDs[0]);
    return null;
  }
  print("product found");
  return response.productDetails;
}

}

This is the result i get

I/flutter ( 7254): Store Temporarily Available
I/flutter ( 7254): product not found

I/flutter ( 7254): airtime123

Solution

You need to use a reserved SKU for the test: android.test.purchased

const Set<String> _kIds = {'android.test.purchased'};
final ProductDetailsResponse response =
    await InAppPurchaseConnection.instance.queryProductDetails(_kIds);

Yes, but we need a product which is not purchased yet.

You may use 'android.test.canceled' instead. developer.android.com/google/play/billing/billing_testing

But we need to test on real ids.
