Send success message to user after logout

PHP Code:

public function logout()
    {
        session()->set('user');
        session()->destroy();
        session()->setFlashdata('success', 'logout successful!');
        return redirect('/');
    } 


Goal: when the user logs out, the application displays the message "logout successful." Problem: How can the flash message be displayed while the session has already been destroyed?

Do not destroy the session. If you destroy it, you cannot use any feature of Session.
