Pager view causing crash in the app for some users in production

[fawadmahmoodwashmen]

Environment

iOS 18.4.1
react native 0.78.2
react-native-pager-view 6.7.1

Description

Hello, We are experiencing issue with our production app where Sentry reporting crashes for some users, it is happening a few events each day & we are having tough time understanding the root cause. Can you please help us on what may have causing this?

EXC_BAD_ACCESS Exception 1, Code 1, Subcode 0 > Attempted to dereference null pointer.

Reproducible Demo

• It happens randomly & has no specific scenario I can share so far, in some devices & some sessions the application crashes. I will post a complete Sentry stack-trace with in this thread.

Getting this in production as well, same exact stack trace. Did you find a fix?
It happens when unmounting the pager view

@mikebouwmans @alex-gale @MrRefactor Hello, anybody struggling with this issue please try this patch, this solved the issue for me in an production app.

react-native-pager-view+6.8.0.patch

[mikebouwmans]

@fawadmahmoodwashmen that's quite a big patch so not able to test it.

Hi @fawadmahmoodwashmen , I’ve identified the culprit: the issue occurs when the pager view is still scrolling during unmounting. @MrRefactor , please let me know if you need any additional details to work on a fix.

What is the status of this issue?

[bestofaIl]

@rohit9625 still exists
react-native-pager-view@^6.8.1:
version "6.8.1"
think it related to #458

[rohit9625]

How we are supposed to fix this issue? I think it should be handled in the upstream.
