[in_app_purchase] Status change from pending to error missing

[bworwa]

Steps to Reproduce

Having the following:

final InAppPurchaseConnection _connection = InAppPurchaseConnection.instance;
StreamSubscription<List<PurchaseDetails>> _subscription;

_subscription = _connection.purchaseUpdatedStream.listen((purchaseDetailsList) async {
  if (purchaseDetails.status == PurchaseStatus.pending) {
    print('pending');
  } else {
    if (purchaseDetails.status == PurchaseStatus.purchased) {
      print('purchased');
    } else {
      print(purchaseDetails.status);
    }
  }
}, onDone: () {
  _subscription.cancel();
}, onError: (error) {
  // TODO: handle error here.
});

await _connection.isAvailable();

final Future<ProductDetailsResponse> _products = _connection.queryProductDetails({==my ids==});

1. Let's assume products' ids are ok.
2. Let's assume we trigger the buy by:

_connection.buyConsumable(
 purchaseParam: PurchaseParam(productDetails: product),
 autoConsume: true,
);

3. If we select "test card, always declines" as payment method (PM) we get PurchaseStatus.error as expected.
4. If we select "test card, always approves" as PM, we get purchased as expected.
5. If we select "slow test card, approves after a few minutes" as PM, we get pending and after a couple of minutes we get purchased, as expected.
6. If we select "slow test card, declines after a few minutes" as PM:

Expected results: as far as I know, we should get pending and after a couple of minutes PurchaseStatus.error.

Actual results: pending, no other event is fired, no matter how long we wait.

Hi, any update on this? Have been facing the same issue. Without the status it is difficult to handle the error & loading state for it.

While not exactly the same problem if the user cancels the dialog box on Android I get PurchaseStatus.cancel but on iOS I get PurchaseStatus.pending which runs my pending code by mistake.

The same reproducible code above should demonstrate the issue. I am looking into a work around but the only choice I seem to have at the moment is to remove the pending logic when in iOS.
