RenderView in Symfony Command usage

Question

How can I use $this->renderView inside a symfony Command (not inside a controller)? I new about the function \"renderView\" but what do I have to setup to use it wihtin a comman

Yet another one: rely on dependency injection, i.e. inject ContainerInterface

namespace AppBundle\Command;

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Psr\Container\ContainerInterface;

class SampleCommand extends Command
{
    public function __construct(ContainerInterface $container)
    {
        $this->templating = $container->get('templating');
        parent::__construct();
    }

    protected function configure()
    {
        $this->setName('app:my-command')
             ->setDescription('Do my command using render');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $data = retrieveSomeData();
        $csv = $this->templating->render('path/to/sample.csv.twig',
                                         array('data' => $data));
        $output->write($csv);
    }

    private $templating;
}

This relies on Symfony to inject the container, which in turn is used to retrieve either templating or twig or whatever you need for your custom command.
