flutter
[in_app_purchase][ios] `AppStorePurchaseDetails.pendingCompletePurchase = true` after calling `completePurchase`
Steps to Reproduce
- Setup a sandbox environment for in app purchase on iOS with a subscription
- Log in to the sandbox account on a iOS device
- Purchase the subscription
- InAppPurchase.instance.purchaseStream emits PurchaseDetails for the subscription
- Call InAppPurchase.instance.completePurchase if pendingCompletePurchase is true
- Restore purchases
- PurchaseDetails.pendingCompletePurchase is still true
Expected results: PurchaseDetails.pendingCompletePurchase = false after call to completePurchase
Actual results: PurchaseDetails.pendingCompletePurchase = true after call to completePurchase
AppStorePurchaseDetails.pendingCompletePurchase returns _pendingCompletePurchase.
I have also tested on Android, there pendingCompletePurchase changes to false as expected.

Hi @andaas4, I just noticed that the value you're referencing in your screenshot is a private setter, so that value shouldn't be accessible to you, but the public getter, pendingCompletePurchase which retrieves the value you'd need is actually showing the correct value.
Is your issue to point out the discrepancy between the two values?
Yeah, I know. If you look at app_store_purchase_details.dart the logic there is bool get pendingCompletePurchase => _pendingCompletePurchase;
I think the value for pendingCompletePurchase shown in the screenshot is from purchase_details.dart with defaults to false, as AppStorePurchaseDetails extends PurchaseDetails, but the actual value returned when accessing pendingCompletePurchase on AppStorePurchaseDetails is the value from _pendingCompletePurchase.
Sorry if that was misleading, just thought it was a good thing to point out. But the issue is still present in my testing, pendingCompletePurchase on AppStorePurchaseDetails is true after calling completePurchase multiple times. @danagbemava-nc
Sorry if that was misleading, just thought it was a good thing to point out.
I just wanted to make sure that we were on the same page. I am seeing something similar to what you're seeing. I don't think this is intended, but I'm not an expert on in_app_purchases. Labeling for further insight from the team. Steps to reproduce can be found in https://github.com/flutter/flutter/issues/98484#issue-1138421429
This can be reproduced with the plugin's example code as well.

Notice that there are 2 values for pendingCompletePurchase and they don't seem to match up with each other.
The private setter also seems to be true

I also have the same issue still (with the version 3.0.7), isn't there any update on this
I have encountered the same situation. Completing a purchase using completePurchase doesn't have any effect on pendingCompletePurchase property. It stays true. Do we have an ETA for a fix?
New information here may be, that my non-consumable is a subscription.
As of 2023, I'm still experiencing this issue. I've a bunch of unfinished purchases stacked up that don't want to complete.
Just adding another voice to the list of people who have this issue... 190 unfinished purchases on one of my test devices!
@danagbemava-nc please this issue is essential it opened 1 year ago and there is no fix until now.
I have the same problem. It's strange that this hasn't been fixed yet. Please fix this problem
Can confirm the issue too.
This bug gets in the way of building "Restore Purchases" functionality properly.
Calling restorePurchases on iOS gets all the previous transactions and restoring them correctly, but expectation is that after completing such restored transactions those will be gone from the purchaseStream.
Completed transactions stay on the purchaseStream and get re-issued again, for example on hot-reload.
We are still experiencing the same issue. Does this problem happen on non-sandbox IOS users?
Title: "Issue with inapppurchase.instance.completePurchase and pendingCompletePurchase for iOS non-consumable purchase"
Description: After calling inapppurchase.instance.completePurchase for a non-consumable purchase on iOS, the pendingCompletePurchase property is consistently returning true, even though it should be set to false after successfully completing the purchase.
Steps to Reproduce:
Initialize the in-app purchase instance. Trigger a non-consumable purchase transaction using appropriate methods. Call inapppurchase.instance.completePurchase() to complete the purchase. Expected Behavior: After successfully completing the non-consumable purchase, the pendingCompletePurchase property should be set to false.
Actual Behavior: Upon calling inapppurchase.instance.completePurchase(), the pendingCompletePurchase property remains true, even though the non-consumable purchase has been completed.
Environment:
Operating System: [e.g., macOS] iOS Version: [e.g., iOS 14] Xcode Version: [e.g., Xcode 12] in_app_purchase Plugin Version: [e.g., 0.5.3] Additional Information:
This issue is specific to iOS non-consumable purchases and has not been observed on other platforms or purchase types. The issue is consistently reproducible on multiple iOS devices running various iOS versions. The application is utilizing the latest version of the in_app_purchase plugin. As this issue impacts the core functionality of our app and affects the user experience, we are actively seeking a resolution or any guidance to overcome this challenge. Any insights or suggestions on resolving this issue would be highly appreciated.
Thank you for your prompt attention to this matter, and we look forward to resolving this issue promptly.

As this issue is already more than a year old, has anyone found a workaround?
Still facing same issue. Any body successfully resolved this issue? Any suggestion or help?
I am stuck on same issue. Any news/updates or workaround? It shows up in development and on TestFlight. Does anyone know if the problem persists in the production environment?
Thank you for any advice
I've encountered this as well. For me it restores subscription purchases correctly at app startup, but when I switch to another app and then back into mine, it sends an entire purchase history as another restore batch
It's really frustrating to find issues that I'm running into documented throughout this forum, but most of the threads are years old. Do I need to use a different library entirely?
Is there a workaround? If this is expected behaviour, the documentation should reflect this as well
Same issue here. Topic opened months ago but there is not any solutions yet. Also someone closed topic #115241 as a duplicate of this topic but there is not any solutions in this topic too.
As i experienced, listening purchase updates returns current subscription renewals with status purchased and it triggers status.Purchased case of example code. So we need a workaround to this.
Hi everyone i'm facing the same issue. Is anyone knows if the problem is only with storekit/testflight or if it possibly be trigger in production mode ? Thanks for answer ! hope it was solved soon

It only appears in storekit/testflight mode, I have never seen it be triggered in production mode.
