Nullpointer: io.ionic.keyboard.CDVIonicKeyboard.onDestroy

[EinfachHans]

I just received the following Crash Report from AppCenter:

io.ionic.keyboard.CDVIonicKeyboard.onDestroy
java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.ViewTreeObserver android.view.View.getViewTreeObserver()' on a null object reference

That's happening for the first time in 6 month, so doesn't seem to be a huge problem, but i think you should know about that one. I can not reproduce that myself, as this seems to be a rare problem

Device: P30 Pro (Android 10)
