我可以从Laravel Controller中删除请求吗？

Question

Can I remove the following line of code

use Illuminate\Http\Request;

form laravel Controller? Is this a good practice? For example, my HomeController:

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{

    public function __construct()
    {
        $this->middleware('auth');
    }

    public function index()
    {
        $totals = [
            'customers' => \App\Customer::count(),
            'jobs' => \App\Job::count(),
            'invoices' => \App\Invoice::count(),
        ];


        $data = [
            'page_title' => 'Dashboard',
            'totals' => $totals
         ];

        return view('home', $data);
    }

}

Here I don't need the "Request", because none of the functions doesn't use that parameter.

To obtain an instance of the current HTTP request via dependency injection, you should type-hint the Illuminate\Http\Request class on your controller method. The incoming request instance will automatically be injected by the service container.

So if you don't want To obtain an instance of the current HTTP request then remove it.
