Open Overlay from background when app is kill state

[Soheldeveloper]

I want to open Overlay from background when app is in kill state. Specially when firebase ping comes in background. So is is possible in this library or not ?

When I am trying to do this, I face following error.

**E/flutter (30813): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(error, Not allowed to start service Intent { flg=0x30000000 cmp=my.package.name/flutter.overlay.window.flutter_overlay_window.OverlayService (has extras) }: app is in background uid UidRecord{25fa346 u0a887 RCVR idle procs:1 seq(0,0,0)}, null, java.lang.IllegalStateException: Not allowed to start service Intent { flg=0x30000000 cmp=com.vivacom.mhealth/flutter.overlay.window.flutter_overlay_window.OverlayService (has extras) }: app is in background uid UidRecord{25fa346 u0a887 RCVR idle procs:1 seq(0,0,0)}

Following is my code for opening overlay in main.dart

    height: 200,
    width: overlay_window.WindowSize.matchParent,
    startPosition: const overlay_window.OverlayPosition(0, 0),
  );
}

        } else {
