use Illuminate\Http\Request;

class ProfileController extends Controller

    private $service;

    public function [1](UserService $service)
    {
        $this->service = [2];
    }

💡 Hint

Common Mistakes

Using wrong method names like 'handle' instead of '__invoke' for the single action method.

Not assigning the constructor parameter correctly.

The constructor is named __construct, it assigns the passed $service to the property, and the single action method is __invoke.
