How to check if parameters were passed in Laravel From Request?

Question

Laravel

I am using Laravel. In the controller for filtering data, I check whether the request is empty, if it is empty, then I redirect, and if not, then I check the validity. Now I'm going to move this to a separate Form Request . How to check if the incoming request is empty using From Request. Similar code in the controller:

if(empty($request->all()))
        {
            return redirect('/');
        }

        $this->validate($request,
            [
                'department' => 'integer|nullable',
                'date' => 'date|nullable'
            ]);

Laravel already has a built-in and normal form validation system. Specify the required field in the validation rules and that's it. If the field is empty, it will redirect back with an error.
How I do:
Create a new file via php artisan make:request NameRequest. In it I create rules of validation of the form. In the controller (or somewhere else), I add the NameRequest to the method and it works itself out. Those. no need to clutter up the controller with form validations.
