Describe the bug Same Issue with me in version ^4.0.3+1 #317

Production Google Play crash reports i have more than 79 people impacted with this error

It started from 20-4-2020 when i added flutter sound plugin and uploaded an update to google paly

Almost all the devices are huawei with android 8 and 8.1

I don’t have a “Huawei Y7 Prime 2019 (HWDUB-Q), 3072MB RAM, Android 8.1” to test flutter run and give you the output. Is this information enough to know the bug?.. tell me if you need anything more

To Reproduce

1. Download and run the app and it crashes in the installation from google play. The problem shows in some phones not all of them.

Expected behavior Don’t crash in production I only added this great and awesome plugin to record audio with the “FlutterSoundRecorder” module … I don’t need a background service to start when the app is installed

So make the service optional if its possible … Thanks for your hard work we really appreciate it

[bsutton]

I’ve pushed a possible fix for this in the 5.0 branch.

Sure 😃 If you still continue to have problems, please enter a new issue, (with your logs, of course, and the result of “flutter pub deps | grep flutter_sound” ). I really hope that everything fixed, now. Good luck 😃 !
