Custom Worker implementation on Laravel 6

[NitishKumarPatra]

Hi I am on a migration phase from 5 to the latest versions, and currently facing the below issue on Laravel 6.
I have extended both WorkCommand and Worker classes on to my custom classes.
I was getting the error

In Container.php line 993:
Unresolvable dependency resolving [Parameter #3 [ <required> callable $isDownForMaintenance ]] in class Illuminate\Queue\Worker

So i added the below block to AppServiceProvider

$this->app->bind(WorkEnvironmentCommand::class, function ($app) {
    return new WorkEnvironmentCommand($app['queue.worker'], $app['cache.store']);
});

I am aware that $app['queue.worker'] injects Illuminate\Queue\Worker during the bind in the above code
But as i have also extended the Worker class, the constructor needs to be initialized with my custom worker class and not the Illuminate class. So i am getting the below error

Argument 1 passed to App\Console\Commands\Queue\WorkEnvironmentCommand::__construct() must be an instance of App\Console\Commands\Queue\Worker, instance of Illuminate\Queue\Worker given, called in D:\laragon\www\diesel2\app\Providers\AppServiceProvider.php on line 77

I am not sure how do i resolve this. Any suggestions?

So i made progress by resolving the bound custom worker in WorkEnvironmentCommand class

public function __construct(\Illuminate\Queue\Worker $worker, Cache $cache)
{
	$this->$worker = \App::make(App\Console\Commands\Queue\Worker::class);
        parent::__construct($worker, $cache);
}

But next i get error

 Unresolvable dependency resolving [Parameter #3 [ <required> callable $isDownForMaintenance ]] in class Illuminate\Queue\Worker

Where and how should i pass this $isDownForMaintenance?

Ok so i resolved the issue
I am adding it down so that if someone gets similar issue, they may find it useful

In AppServiceProvider ->

$this->app->bind(WorkEnvironmentCommand::class, function ($app) {
    $isDownForMaintenance = function () {
    return $this->app->isDownForMaintenance();
    };
    return new WorkEnvironmentCommand(\App::make(Worker::class,['isDownForMaintenance' => $isDownForMaintenance]), $app['cache.store']);
});

And reverted back my _contruct() in WorkEnvironmentCommand to

/**
* Create a new queue listen command.
*
* @param  \App\Console\Commands\Queue\Worker  $worker
* @param  \Illuminate\Contracts\Cache\Repository  $cache
* @return void
*/
public function __construct(Worker $worker, Cache $cache)
{
    parent::__construct($worker, $cache);
}
