[in_app_purchase] Fix finishing purchases upon payment dialog cancel… #3106

dennis-tra · 2020-10-02T10:14:13Z

Description

This PR fixes finishing purchases upon payment dialog cancellation on iOS.

When the user cancels the payment dialog there is no transactionIdentifier which means the transaction cannot be finished in the current implementation and therefore not initiated again.

  NSArray<SKPaymentTransaction *> *pendingTransactions =
      [self.paymentQueueHandler getUnfinishedTransactions];

  for (SKPaymentTransaction *transaction in pendingTransactions) {
-    if ([transaction.transactionIdentifier isEqualToString:transactionIdentifier]) {
+    // If the user cancels the purchase dialog we won't have a transactionIdentifier. So if it is


I think these two words break the line. Same below.

Prefer lightweight generic. Consider adding a type for the Map. For example: Map<String, String>

LHLL

LGTM! Thanks.

Looks like the version needs to be updated from pubspec.yaml

Still getting an error after calling completePurchase method in version 0.3.4+11.
PlatformException(storekit_invalid_argument, Argument type of finishTransaction is not a Dictionary, null, null)

EDIT: Worked with latest version 0.3.4+12

Hi! I'm experiencing the same error PlatformException(storekit_invalid_argument, Argument type of finishTransaction is not a Dictionary, null, null)

EDIT: My bad, it is working after switching to a new sandbox account (IDK if it has something to do but just in case) and also running flutter clean! Thanks for the fix!

DangKhoi1997 · 2020-10-07T09:11:45Z

Updated to version 0.3.4+12 but it still not pop up purchase dialog :(. Anyone has same error ??

@DangKhoi1997 I think dialog not showing up is a different issue and not related to this PR. Apple Pay UI/dialog is not showing up is related to not finishing transactions. Can you try something similar to following code to see if your problem is solved:

class PurchaseService{
    final _connection = InAppPurchaseConnection();

    const PurchaseService(){
          _connection.purchaseUpdatedStream.listen((detail) {
               ...
              // Verify the receipt for succeeded transactions and handle the error for the failed
              // transaction here.
              _connection.completePurchase(detail);
          });    
    }
}

Updated to latest version 0.3.4+12 but we are still not able to buy again whenever we cancel the purchase dialogue. The button works fine if we complete the purchase flow and I am able to buy many time if the purchase flow ends correct, but whenever I cancel and try to tap again the button it won’t open the purchase dialogue. Do we need to add any additional code to our implementation?

@hai199580 I did not find a solution for this issue. I recommend you to use Revenue Cat, we implemented it in 4 hours and it works fine. I will keep using Revenue Cat until this issue is solved. Hope it helps!
