The property $path is not used and could be removed.

    private static $uri;

    public function __construct(){

This method seems to be duplicated in your project.

        # Config
        self::$config = (new Config)->get();
        # Application
        self::$app = new Application;
        # View
        self::$view = new View;
        # Js
        self::$js = new Js;
        # Css
        self::$css = new Css;
        # Title
        self::$title = new Title;
        # Desctiption
        self::$description = new Description;
        # Keywords
        self::$keywords = new Keywords;
        # Uri
        self::$uri = new Uri;
    }

    public function __get($name){
        self::$property= $name;
        return new self;
    }

    public function __call($_name,$value){
        if(isset($value[0]) && !empty($value[0]) && is_array($value[0])) extract($value[0]);
        $file = self::$config['core']['widget'].'/'.self::$property.'/'.$_name.'.phtml';
        if(is_file($file)) require($file);
    }

}
?>

It is not recommended to use PHP's closing tag ?> in files other than templates.
