Same as this comment , why don't add FQCN for RedirectResponse class ?


:method:`Symfony\\Bundle\\FrameworkBundle\\Controller\\Controller::render` (service: ``templating``)
.. code-block:: php

$templating->renderResponse($view, $parameters, $response);

:method:`Symfony\\Bundle\\FrameworkBundle\\Controller\\Controller::renderView` (service: ``templating``)
.. code-block:: php

$templating->render($view, $parameters);

:method:`Symfony\\Bundle\\FrameworkBundle\\Controller\\Controller::stream` (service: ``templating``)
.. code-block:: php

use Symfony\Component\HttpFoundation\StreamedResponse;

$templating = $this->templating;
$callback = function () use ($templating, $view, $parameters) {
$templating->stream($view, $parameters);
}

return new StreamedResponse($callback);
