PHP Warning: Undefined property: ReflectionNamedType::$name in /home/user/Downloads/IsomiR_Window_Built/opt/lampp/htdocs/isomirwindow/vendor/laravel/framework/src/Illuminate/Container/Container.php on line 885
PHP Fatal error: Uncaught ReflectionException: Class “” does not exist in /home/user/Downloads/IsomiR_Window_Built/opt/lampp/htdocs/isomirwindow/vendor/laravel/framework/src/Illuminate/Container/Container.php:752

 public function build($concrete)
    {
        // If the concrete type is actually a Closure, we will just execute it and
        // hand back the results of the functions, which allows functions to be
        // used as resolvers for more fine-tuned resolution of these objects.
        if ($concrete instanceof Closure) {
            return $concrete($this, $this->getLastParameterOverride());
        }

        $reflector = new ReflectionClass($concrete); //line752

        // If the type is not instantiable, the developer is attempting to resolve
        // an abstract type such as an Interface of Abstract Class and there is
        // no binding registered for the abstractions so we need to bail out.
        if (! $reflector->isInstantiable()) {
            return $this->notInstantiable($concrete);
        }

        $this->buildStack[] = $concrete;

        $constructor = $reflector->getConstructor();

        // If there are no constructors, that means there are no dependencies then
        // we can just resolve the instances of the objects right away, without
        // resolving any other types or dependencies out of these containers.

            array_pop($this->buildStack);

            return new $concrete;
