Memory Leak (Thread) does not dispose.

[ScorpiosCrux]

Describe the bug
Whenever I put the overlay in the background, a new thread/isolate is created but never disposed.

This started happening when I started using:

@pragma("vm:entry-point")
void overlayMain() {
  // Ensure's that the Flutter engine is initialized before any dart calls.
  WidgetsFlutterBinding.ensureInitialized();
  
  runApp(const MaterialApp(
    debugShowCheckedModeBanner: false,
    home: SystemOverlayWidget(),
  ));
}

To Reproduce
Click the circle button to put the app into the background (with circle button), and then reopen the app without closing it (swiping up from square button)

Expected behavior
The overlay thread should be shutdown when the following is called

await SystemAlertWindow.closeSystemWindow(
    prefMode: SystemWindowPrefMode.OVERLAY,
);

Versions (please complete the following information):

• SystemAlertWindow: 2.0.0
• Device: Orange Pi 5
• OS: Android 12

Let me know if you need more information.

I have the same problem:

E/flutter (12162): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method removeCallBackHandler on channel in.jvapps.system_alert_window)
E/flutter (12162): #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:332:7)
E/flutter (12162):
E/flutter (12162): #1 SystemAlertWindow.removeOnClickListener (package:system_alert_window/system_alert_window.dart:50:12)

Did you made it solving this?
