Foreground service type missing in to the new version 6.4.0
The foreground service type is missing in the new version 6.4.0. Due to this the Android app crashes continuously.

I got this error when trying both version 6.3.0 and 6.4.0. Is it related to this package's error?

Check runtime prerequisites. https://developer.android.com/about/versions/14/changes/fgs-types-required#microphone
You must grant RECORD_AUDIO permission before starting the service.
@Dev-hwang My issue is with the MEDIA_PROJECTION service. How exactly do I grant it before the service starts? It's already specified in the manifest.
Plugin version - 6.4.0

I am also experience issues on Android regarding the FOREGROUND_SERVICE_MICROPHONE, I downgraded to 6.3 to specify the foregroundServiceTypes. The ForgroundService starts as expected but when I try to start my audio recording with the record dependency I get an error from the record that I lack the permission. As @bhavinb98 and @tatuan19 are using the FOREGROUND_SERVICE_MICROPHONE I wonder how you manage to record audio in the FS.
@knma1992 Hmm not sure. My app asks for the access microphone permission during startup, after that there's no other configuration. My foreground service code is pretty much similar to the one in the readme.
@bhavinb98 Mine as well, recording works but not in the FS for some reason, is your app on github?
Let me just post my code here, maybe I am doing something obviously wrong.

@knma1992 Have you tried asking for the record permission outside of the task handler function? or is it the first time it asks for it?
Currently, I grant permission on a separate screen using the permission handler and I only access the screen from which I start my FS when I have granted all my permissions. What is weird is the fact that if I check permission in my task handler with the permission handler it is granted.
final microphonePermission = await Permission.microphone.isGranted;
But record for some reason does not.
Looking into the ForegroundService was a mistake, I should have debugged the record plugin way earlier. When the record plugin checks for permission and when it sinks the audio buffer into the EventChannel it does so via an activity variable that won't be set when the record plugin is started from the second dart entry point. I forked the record plugin and changed it accordingly.
This is the old implementation.
fun sendRecordChunkEvent(buffer: ByteArray) { activity?.runOnUiThread { eventSink?.success(buffer) } }
My implementation:
fun sendRecordChunkEvent(buffer: ByteArray) { uiThreadHandler.post(Runnable { eventSink?.success(buffer) }) }
Currently, I don't change the permission check implementation inside record as I can check for permissions using the permission_handler plugin and I have no idea how to supply the context to the record plugin. Thanks @bhavinb98 for the help.
