php - How can I get my session data inside my constructor function in the controller

Question

This is a part of the code.

        class StudentController extends Controller
        {
                public function __construct(Request $request) 
                {
                    $school = session('school_data');

                    $this->middleware($school); 
                }
        }

Now, I've also tried checking the $school by using dd($school) but it returns null

NOTE: The session variable works in other functions inside the same controller.
