Exception while trying to read notification channels

[ueman]

Describe the bug

The following code

final _localNotifications = FlutterLocalNotificationsPlugin();
final androidPlugin = _localNotifications.resolvePlatformSpecificImplementation<AndroidFlutterLocalNotificationsPlugin>();
final allChannels = await androidPlugin?.getNotificationChannels();

results in the following exception

PlatformException(getNotificationChannelsError, Attempt to invoke virtual method 'int android.media.AudioAttributes.getUsage()' on a null object reference, java.lang.NullPointerException: Attempt to invoke virtual method 'int android.media.AudioAttributes.getUsage()' on a null object reference

To Reproduce
Unfortunately, we're seeing this only in production without any actionable reproduction steps.
The app is in foreground and active, though.

Expected behavior
I expect no exception to be thrown.

Sample code to reproduce the problem
See above

This is not a duplicate of #2309 but it's pretty similar.
