[Windows] Flutter app doesn't launch automatically when an API hit is received while the app is closed/killed.

[nilkanthp-interpay]

Hi
I'm encountering an issue where the Flutter app doesn't launch automatically when an API hit is received while the app is closed.

Expected Behavior:
App Running: No action should be taken.
App Closed: The app should launch in response to the API hit.

Actual Behavior:
App Running: The app functions as expected.
App Closed: The app doesn't launch.

Steps to Reproduce:
Close the app completely.
Trigger the API hit.

Additional Information:
Platform: Windows
Plugin Versions: launch_at_startup: ^0.3.1

Code:

PackageInfo packageInfo = await PackageInfo.fromPlatform();
    launchAtStartup.setup(
      appName: packageInfo.appName,
      appPath: Platform.resolvedExecutable,
    );
    await launchAtStartup.enable();

startServer();
```

```
void startServer() async {
  final server = await HttpServer.bind(
    InternetAddress.loopbackIPv4,
    8080,
  );
  print('Listening on localhost:${server.port}');
  SdkLogger.debug('Autostart-TAG', 'Listening on localhost:${server.port}');
  await for (HttpRequest request in server) {
    SdkLogger.debug('Autostart-TAG', 'Inside Listening on localhost:${request.method} : ${request.uri.path}');
    if (request.method == 'POST' && request.uri.path == '/sale') {
      print('Received API call to launch app');
      SdkLogger.debug('Autostart-TAG', 'Received API call to launch app');
      checkAndLaunchApp();
    }
    request.response
      ..write('Request received')
      ..close();
  }
}
```

```
Future<void> checkAndLaunchApp() async {
  // Define the name of the process to check
  const processName = 'myapp.exe';
  // Replace with your app's process name
  // Get the list of currently running processes
  final result = await Shell().run('tasklist');
  final processes = result.outText;
  // Check if the process is running
  SdkLogger.debug('Autostart-TAG', 'CHECK PROCESS:: => ${processes.contains(processName)}');
  if (!processes.contains(processName)) {
    // If not running, launch the app
    await Process.run('myapp.exe', []);
    // Replace with the actual path to your app
    print('App launched successfully.');
    AppConstant().toast('App Launch Successfully');
    SdkLogger.debug('Autostart-TAG', 'App launch successfully');
  } else {
    print('App is already running.');
    AppConstant().toast('App is already running');
    SdkLogger.debug('Autostart-TAG', 'App is already running');
  }
}
```


Note: 
 => await Process.run('C:\Program Files (x86)\myapp\myapp.exe', []);  // also try this where app install with full path instead of myapp.exe
 => this .exe path is also add in environment variable
