W/FlutterJNI(23350): Tried to send a platform message to Flutter, but FlutterJNI was detached from native C++. Could not send. Channel: x-slayer/accessibility_event.

Issue Description

Problem:
I am attempting to identify the currently active application using the Flutter Accessibility Service. After following the instructions provided on the package’s pub.dev page, I utilized event.packageName to achieve this. However, upon implementing the code in my main.dart, I encountered the following error:

W/FlutterJNI(23350): Tried to send a platform message to Flutter, but FlutterJNI was detached from native C++. Could not send. Channel: x-slayer/accessibility_event. Response ID: 131

This error occurs after my application is closed, and persists even when the application is reopened.

Steps to Reproduce:

1. Install the flutter_accessibility_service package and follow the instructions in the README.
2. I'm just adding the following damn code to the MyApp class in main.dart:

   StreamSubscription<AccessibilityEvent>? _subscription;
   List<AccessibilityEvent?> events = [];
   String currentApp = '';
   
   String getCurrentApp() {
     if (_subscription?.isPaused ?? false) {
       _subscription?.resume();
       return '';
     }
     _subscription = FlutterAccessibilityService.accessStream.listen((event) async {
       setState(() {
         currentApp = event.packageName!;
       });
       log("current event : $currentApp");
     });
     return currentApp;
   }
   

3. Run the application on an emulator and enable accessibility permissions.
4. Close the app.

Expected Behavior: The getCurrentApp() function should log the package name in the terminal, but it does not execute as expected, and no package name is logged.

Actual Behavior: The error message is displayed, and the expected behavior does not occur.

any idea how to fix it?
