Flutter porcupineManager.delete() when app is closing don't release resources correctly

Hello, When I call manually porcupineManager.delete() before closing app the resources are released correctly, and when I reopen the app I can create and start a new porcupineManager in a correct way. But when I try to call porcupineManager.delete() automatically when the StatefulWidget is closed I continue to receive the following message in the debug:

W/FlutterJNI(18227): Tried to send a platform message to Flutter, but FlutterJNI was detached from native C++. Could not send. Channel: flutter_voice_processor_events. Response ID: 0 The problem is that even if I close and restart the app I continue to receive this message and the voice recognition doesn’t work properly.

How can I solve this?

@maddionatoplus I was also able to reproduce this in our demo as well, however, this behaviour is only ever observed while trying to delete porcupineManager from the paused state when the back button is pressed on an Android device. If you call delete on back button press from the inactive state it works fine. If you call delete from the paused state in any other situation it works as intended. This seems to be a shortcoming of Flutter and not a bug in our SDK (though we will document this). I would suggest you either call delete when the state enters inactive or handle the Android back button event separately using the WillPopScope class.

Thank you! WillPopScope worked well!
