如何解决Uncaught ReflectionException：php seytar路由器中不存在类配置

I created a middleware in web.php in my project for testing.

Note: I'm using this package https://github.com/seytar/php-router

There is no problem until I use Redirect or Url to redirect.

function isLogin() {
    return false;
}

class checkLogin {
    public function handle(\Illuminate\Http\Request $request, Closure $next, array $guards = [])
    {
        if (isLogin()){
            return $next($request);
        }
        return \Illuminate\Support\Facades\Redirect::to('/');
    }
}

Route::get('/', function () {
    return "This is home page!";
});

Route::get('/dashboard', [
    'middleware' => 'checkLogin',
    'uses' => function () {
        return "This is dashboard!";
    }
])

This is my error:
