Crash in ios

[yringler]

I'm seeing a crash in crashalytics. (I'm also using audio_service)

I notice that the free RAM looks limited. Do you think this is just because my app is currently RAM heavy?

Model: iPhone 6s
Version: 13.3.0 (17C54)
RAM free: 58.27 MB

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000010

It could be that _eventSink hasn't been initialised yet, so that method may need to have a guard like this:

if (!_eventSink) return;

I also have a lot to learn about iOS memory management still, so maybe it's something even more crazy like the self instance being free'd. But I'd start with the above guard first. In any case, I am going off to sleep now. You are of course welcome to try the above code suggestion and see if it works for you in the meantime, assuming you are able to reproduce the issue.

Thank you! When the plugin is updated I'll use it and redeploy, and see if that stops this crash.

I've added the above line of code to the latest git commit if you'd like to test it.

Thanks! App works like a charm now. Would recommend releasing as fast as possible as this is quite the critical error on iOS

[ryanheise]

Great! I was waiting on confirmation on some other iOS code that will also be included in the release, but it seems that things are working well enough that you haven't noticed any issues so I've just published a new release. If you have some spare time, I would also appreciate your feedback on #35 .

It's been 24 hours, and I'm not seeing any crashes now that I'm using the latest commit.

One interesting bit of context: One beta tester showed me that the crash happened when

1. audio was playing,
2. he sent voice note in whatsapp
