   Hi @davidchzh
   For the issue to be workable, can you provide a completed and minimal reproducible code sample that doesn’t include 3rd party plugins or complex production code? (you may look into plugin sample code and use it to see if the issue happens on your side). And please provide the entire crash stack trace as well. Thank you!

   Thank you for your reply!
   For this question, I already know where the problem lies, which is caused by calling the following code.

       var transactions = await SKPaymentQueueWrapper().transactions();
       for (var skPaymentTransactionWrapper in transactions) {
         SKPaymentQueueWrapper().finishTransaction(skPaymentTransactionWrapper);
       }
   

   The embarrassing thing is that I have forgotten why I added this code. I would like to ask if deleting this logic will affect the process, or if there is a new method in the latest version to replace it.

   From my point of view, since you invoked completePurchase, it will call completePurchase. Perhaps manually calling finishTransaction is being used in case error handling. Please see #91164 if it assembles your case or not.

   It seems that the two are the same problem. According to my current understanding, the purpose of this code is to "end the last transaction if the last call fails."
   In my code, I will call this logic regardless of whether the last call failed.
   In version 3.1.13, this did not cause an error. It caused an error when I upgraded to version 3.2.

    #91164 is a documentation issue and the original comment showing it's a type cast error.

    In version 3.1.13, this did not cause an error. It caused an error when I upgraded to version 3.2.

    It could be a regression but need to know the in_app_purchase_storekit version as well. Please also try to narrow the sample code down into a minimal one that can produce the error as reported.

    When running the demo, I found another problem.
    After selecting the product to call up the payment page, click the x in the upper right corner to cancel the payment, and the page will remain in the loading state.
    The code does not make any changes to the demo logic. It just changes the product id.

    Sample code

    (I collapsed the sample code on your comments above since they are too long for others to grasp the issue.)

    When using your sample code at #154763 (comment), I can see the fatal crash on iOS.

    To find regression, I was forced to use in_app_purchase: 3.1.13 (with dependency_overrides) but the crash persists. I think it's because in_app_purchase_storekit is still on the latest version 0.3.18+1. I traced it by trying some older in_app_purchase_storekit versions on release timeline of in_app_purchase and in_app_purchase_storekit, I found the crash also occurs with in_app_purchase_storekit: 0.3.8+1 but the app is not terminated as the latest version, I can see the trace, though.

    [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(storekit_finish_transaction_exception, NSInvalidArgumentException, Cannot finish a purchasing transaction, null)
    #0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:648:7)
    #1      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:334:18)
    <asynchronous suspension>
    #2      SKPaymentQueueWrapper.finishTransaction (package:in_app_purchase_storekit/src/store_kit_wrappers/sk_payment_queue_wrapper.dart:162:5)
    <asynchronous suspension>

    I haven't found a version of in_app_purchase_storekit that didn't cause this error, if you can find one, please share it.

    In the meantime, I will mark this as a regression.

    We are also seeing this issue in iOS as of the past couple weeks. We had a similar workaround mentioned above to complete pending transactions prior to attempting a purchase. I think I added this about a year ago because we were having problems with the purchase flow and someone else recommended doing it. It seems that it's now causing a "crash to desktop" native error in iOS.

    I've tried removing this workaround, but am experiencing other strange behavior which I'm currently trying to debug.

    var transactions = await SKPaymentQueueWrapper().transactions();
        for (var skPaymentTransactionWrapper in transactions) {
          SKPaymentQueueWrapper().finishTransaction(skPaymentTransactionWrapper);
        }
    

    Error:

    *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot finish a purchasing transaction'
    *** First throw call stack:

    Downgrading from in_app_purchase 3.2.0 to either 3.1.10 or 3.1.13 fixed the issue for me.
