Laravel 5.4 $ redirectTo不工作

I am stuck with getting the redirectTo() function override in my LoginController.php as shown in the Laravel docs here.

My controller contains:

/**
 * URI where we redirect to after login
 *
 * @var string
 */
protected $redirectTo = 'player/home';

/**
 * Set route redirect
 *
 * @return mixed
 */
protected function redirectTo()
{
    dd("STOP"); <-- does not trigger

    if (session()->has('game.details')) {
        return route(session()->get('game.details.setup_route'));
    } else {
        return 'player/home';
    }
}

Why would the dd never trigger and the page always redirects to player/home? Thanks

Although I did not get the method override working, I solved it by changing these lines in the login method:

    if ($this->attemptLogin($request)) {
        session()->put('game.details', Game::findByUUIDOrFail($uuid));

        $this->redirectTo = route(session()->get('game.details.setup_route'));

        return $this->sendLoginResponse($request);
    }

If you comment $this->middleware("guest") in the constructor of Auth\RegisterController or change the line about guest middleware in the Kernel.php it will be worked.

If you have run php artisan auth

change the RedirectIfAuthenticated Middleware like so

class RedirectIfAuthenticated
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string|null  $guard
     * @return mixed
     */
    public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->check()) {

            return redirect('/home');//change the redirect here
        }

        return $next($request);
    }
}
