Seems to be indeed coming from the plugin. There was an old similar but fixed issue: #32462
Labeling it for further investigation as there doesn't seem to be reproducible use case.

encounter the same issue.

Hello, I don't think my comment is related to the original issue, however it seems to be related with @deskangel and @ozzy1873 comments.
In Crashlytics recently I started to see plenty of similar crashes (for the past 7 days 77 users affected).
Important (which may be different to the original issue)
In the case of my app the crashes happen:
Please check these stack traces from Crashlytics:
Stack trace 1 (very common)
Stack trace 2 (much less common)

I have found that developers of RevenueCat also had a similar issue that happened mostly on Huawei devices which was resolved after some investigation. Maybe that can be helpful in the resolution of this issue.

@darshankawar RevenueCat/purchases-flutter#245 (comment)
please look at this comment if possible I think this is the issue.
this issue has been active for so long and it affected a lot of our user base but at the same time it is hard to reproduce but crashlytics reports it frequently.

Looks like the original issue originates from
onSkuDetailsResponse.I just wanted to add that I'm seeing the same issue from
queryProductDetailsAsyncon the latest version of the plugin:Seems to happen exclusively on Samsung and Huawei devices on my end, and 100% of the crashes happen when the app is in the background:
Edit:
I looked into the revenuecat issue mentioned before and it looks like the same issue is relevant here.
RevenueCat/purchases-android#369 mentions:
"BillingClient, in some cases, issues multiple responses to the querySkuDetailsAsync and queryPurchaseHistoryAsync callbacks. This was causing crashes for Flutter users and is currently the top crash in the sdk console."
Meaning the plugin needs to take care that even if
querySkuDetailsAsyncissues multiple responses, only the first should be taken into account.FluffyBunniesTasteTheBest commentedon Jul 8, 2024
Same here with version 3.1.13 and a slightly different stack trace. Happens mainly on Huawei devices, though some Samsung, Nokia and TCL devices are reported as well. 56 effected users, of which 30 are running either Android 8 or 8.1. The remaining 26 crashes are distributed over Android 9 - 14.
Second stack trace got reported for five users:

Same here with 3.22.3
Stack trace from Vivo S19 running Android 14
More stack traces from Itel P17 running Android 11
