How can I check if the app is using the ConvertEmptyStringsToNull Middleware in Laravel?

I am writing a Laravel console-command. When the command is called using the command-line, I need to know if the ConvertEmptyStringsToNull is a registered middlewear in the Application or not.

When I looked at Illuminate\Foundation\Http\Kernel I can see that it has a public method called hasMiddleware that should give me the answer I am looking for.

However, I am not sure what is the correct way to create a new of the App\Http\Kernel which expends the Illuminate\Foundation\Http\Kernel class. More, I am not sure if there is a better way to check if the app has a middleware beside creating a new instance of the Kernel class.

My command class extends the Illuminate\Console\Command like this

use Illuminate\Console\Command;

class TestCommand extends Command 
{
    public function handle()
    {
        $router = new \Illuminate\Routing\Router(); // this is not working!
        $kernel = new \App\Http\Kernel($this->getLaravel(), $router);  // $this->getLaravel() is a method that the Illuminate\Console\Command has which return the instance of the application
    }
}

Is there a better way to check if the app has the ConvertEmptyStringsToNull middleware beside creating a new instance of the Kernel class? Is there a way to access the Kernel class without creating a new instance? If not, what is the proper way to create a new instance of the Kernel class?
