Flutterfire: 🐛 [Cloud Firestore] Fatal Exception: java.lang.NullPointerException Attempt to invoke virtual method 'void f.a.b.a.j.a(java.lang.String, java.lang.Object)' on a null object reference

Bug report

These issues only happen on Android phones only. It worked fine in iOS. I'm using Flutter 1.20.3 and use cloud_firestore ^0.14.0+2

Fatal Exception: java.lang.NullPointerException

[Ehesp]

Does this happen when any specific code is run?

[joniaiuser]

I think for mine it's when they are trying to link their account to a Google account after signing in with an anonymous account.

sorry there were two instances... one is during normal sign-up. I cannot tell if it's Google or Mobile number. But it triggered a crash in these two instances.

Hi @hansels
Can you please provide flutter run --verbose logs, and a minimal complete reproducible code sample
Thank you

Hi @hansels
The logs you provided doesn't contain Fatal Exception
Can you please provide flutter run --verbose with fatal exception and a complete reproducible minimal code sample
Thank you

[hansels]

Hi @TahaTesser
I can't reproduce the Fatal Exception on my side, the error that I get is from my Firebase Crashlytics logs
Thanks

[bdthombre]

Any updates...facing same issue

[DeanPack]

Pinging this thread to keep it going. I have this same issue. Right now it looks like I'll have to revert All of our firestore plugins

Also having the issue. One interesting fact is that it only happens on Android 10 in my case.

We see the bug on more than just android 10, so it must be a coincidence for you i guess?

[Ehesp]

Appreciate there is an issue here but we're going to need more than stack traces. Does anyone have a reproducible snippet of code which causes this?

[DeanPack]

Unfortunately I haven't been able to reproduce the issues, and the users who are experiencing this issue haven't reported the bug. I'm keeping a very close eye on this on our app. The main thing I hear from other threads on this issue is that it has something to do with coming from the background. like if you close the app with the back button and reopening the app
