Render with Twig_Loader_Filesystem

<?php

class TwigRenderer
{
    public $twig;

    public function __construct($templateDirectory)
    {
        $loader = new Twig_Loader_Filesystem($templateDirectory);
        $this->twig = new Twig_Environment($loader);
    }

    public function render($viewPath, $params=[]){
        echo $this->twig->render($viewPath,$params);
    }
}

Create a renderer with the templates directory path Create a global variable with the flash instance and render the page.

$renderer = new TwigRenderer(__DIR__.'/templates');

$renderer->twig->addGlobal('flash', $flash);

$renderer->render('home.twig');

In the view (a partial for example)

{% if flash.hasSuccess() %}
    <div class="alert alert-success">
        {{ flash.getSuccess() }}
    </div>
{% endif %}

{% if flash.has('error') %}
    <div class="alert alert-danger">
        {{ flash.getMessage('error') }}
    </div>
{% endif %}

Or with multiple messages for example

{% if flash.has('success') %}
    {% for message in flash.getMessages('success') %}
        <div class="alert alert-success fadeIn animated">
            {{ message }}
        </div>
    {% endfor %}
{% endif %}
