Use {{ dump() }} and {% dump() %} in Twig templates

[steevanb]

Hi,

According to the documentation: https://symfony.com/doc/current/templates.html#the-dump-twig-utilities, we have to execute composer require --dev symfony/var-dumper to have {{ dump() }} and {% dump() %} in Twig templates.

But with only this command, we have access to only {{ dump() }} (original Twig function, just a var_dump() and do not use the var-dumper dump() function) and not {% dump() %} (error : Unexpected "dump" tag (expecting closing tag for the "block" tag defined near line 17).)

So, to make it works, we need to have symfony/debug-bundle installed too.

I'm not sure it's a documentation issue, or if we should have var-dumper used by Twig only with the installation of symfony/var-dumper, as written in the documentation?
