Using the "Twig_Extension" class is deprecated since Twig version 2.7

[poaq]

any plan to update it?

solution:
Twig\Extension\AbstractExtension intsead of twig_extension
Twig\TwigFunction instead of Twig_SimpleFunction

create yaml file for config: google_tag_manager.yaml (this info is lack in docs)

@xyNNN would update of twig classes be accepted? That means dropping support for old symphony versions and allow Twig v3.

We can drop it, sure. My suggestion is to update twig as dependency and create a new major release (3.x) for the new Symfony version, so we can support the old versions with the 2.x release. Feel free to make a pull request 👍 Thanks!
