Other info

I'm using TestFlight with this app and already registered an IAP there, its status is Waiting for Review and I've already checked with @lukepighetti that his IAP worked even with this status.

Also, neither catchError or try/catch block are working on this code I'm using:

 Future<List<IAPItem>> refreshProducts({bool includeTests = false}) async {
    final items = _skus.values.toList();
    if (includeTests && _platformVersion.contains("Android"))
      items.addAll(_tests);
    Logger.log(TAG,
        message: "Requesting ${items.length} SKUs: ${items.toString()}");
    List<IAPItem> products = [];
    try {
      await FlutterInappPurchase.getProducts(items)
          .catchError((exception, stacktrace) {
        Logger.log(TAG,
            message:
                "Couldn't refresh products, error: $exception, $stacktrace");
      }).then(products.addAll);
    } catch (error) {
      Logger.log(TAG, message: "Couldn't refresh products: $error");
    }
    Logger.log(TAG, message: "Got: ${products?.length} products");
    if (products != null && products.isNotEmpty) {
      _availableProducts.clear();
      _availableProducts.addAll(products);
    }
    return _availableProducts;
  }

@gildaswise You should use the whole name for productId.
I hope you take a look at the product detail on App Store connect (iTunes connect).
Check the contract info and fill the right info.
Please refer to the example project, also.

Can confirm that this is happening to me as well. Using the full example from GitHub, but receive no products nor error. Have also added a product with 'Waiting for Review' status.

Here is all of my code for IAP for subscriptions. Maybe it's helpful. It works on iOS and Android. I am package locked into 24f85b79b1d8c023f2f1e28069315bd5149b4cfc

class Store {
  static Store _instance = new Store();
  static Store get instance => _instance;
  static String sku = 'when_coin_premium';

  static setup() async {
    await FlutterInappPurchase.prepare;
    final bool isSubscribed = await checkSubscribed();
    _saveToFirebase(isSubscribed);
    FlutterInappPurchase.endConnection;
  }

  static Future<bool> subscribe() async {
    try {
      await FlutterInappPurchase.prepare;
      await FlutterInappPurchase.getSubscriptions([sku]);
      await FlutterInappPurchase.buySubscription(sku);
      FlutterInappPurchase.endConnection;
      await _saveToFirebase(true);
      return true;
    } catch (e) {
      return false;
    }
  }

  static Future<bool> checkSubscribed() async {
    bool isSubscribed = await FlutterInappPurchase.checkSubscribed(
      sku: sku,
      duration: Duration(minutes: 5),
      grace: Duration(minutes: 1),
    );

    await _saveToFirebase(isSubscribed);
    return isSubscribed;
  }

  static Future<void> _saveToFirebase(bool isSubscribed) =>
      User.instance.ref.child('subscribed').set(isSubscribed ?? false);
}

My code is working on Android so would be weird that it wouldn't be working on IOS.

I tried calling buyProduct without calling getProducts before and finally got an error:

[PURCHASE_MANAGER] Couldn't buy product, error: PlatformException(E_DEVELOPER_ERROR, Invalid product ID., null)

But I called buyProduct with the exact productId that is on App Store Connect's In-App Purchases section, it doesn't make sense.

@gildaswise Could you check issue and issue here? Also did you complete the Agreements, Tax and Banking in itunesconnect? I feel this is problem with your appstore environment and not with the plugin.

[gildaswise]

Finished Agreements, Tax and Banking and getProducts is finally working, but now I'm receiving this error on buyProduct:

[PURCHASE_MANAGER] Couldn't buy product, error: PlatformException(E_UNKNOWN, An unknown or unexpected error has occured. Please try again later., null), stacktrace: 
#0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:551:7)
#1      MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:279:18)
<asynchronous suspension>
#2      FlutterInappPurchase.buyProduct (package:flutter_inapp_purchase/flutter_inapp_purchase.dart:212:12)

[RobertBrunhage]

@gildaswise Did you have to wait for the Agreements, Tax and Banking status to be done or can you fetch products when it is pending?

[gildaswise]

@RobertBrunhage I had to click Request on the Paid Applications contract and then fill all forms (except for the AUS' tax info one). A few minutes later, when it moved to Contracts In Effect, I could get getProducts working, but I still can't finish the IAP with buyProduct.

Update: it worked now (maybe it had a delay?) on a physical device (iPhone 7+), but nothing on the Simulator yet.

[hyochan]

@gildaswise Actual payment test should be working only on real device with sandbox account. You can only testing fetching in simulator. Will close this since it seems np.

[lukepighetti]

Payment test and notifications are physical device only on iOS
