$di->set('flash', function () {
    $flash = new FlashDirect(
        array(
            'error'   => 'alert alert-danger',
            'success' => 'alert alert-success',
            'notice'  => 'alert alert-info',
            'warning' => 'alert alert-warning'
        )
    );
    return $flash;
});I'm using flash with customized. I need to modify delimeter (p), icon (type based icons) and custom button inside (link, close button).
How can i customize default flash options ?
