[Question]: Crash trace found at Crashlytics unregisterNetworkCallback

[nikorehnback]

What is your question?

Hi,

I found existing bug ticket of the similar issue: https://github.com/fluttercommunity/plus_plugins/issues/1025

However, I cannot reproduce the bug, have only bunch of traces in Crashlytics for Android 11-14. I have been trying to look source code and understand in which scenario this could happen, but it remains unclear.

Also found this where exception was happening and workaround was made to catch the error: https://android-review.googlesource.com/c/platform/frameworks/support/+/828360/1/work/workmanager/src/main/java/androidx/work/impl/constraints/trackers/NetworkStateTracker.java

Any guidance how to proceed with this?

If ConnectivityBroadcastReceiver would catch the exception, any ideas what harm could that cause?
