PHP 8.0 compatibility

[jmsche]

Tests are also run against PHP7.4.

So, the tests pass, but Travis fails because of this deprecation:

Since symfony/twig-bundle 5.2: Accessing the "twig" service directly from the container is deprecated, use dependency injection instead.

However I can't find a way to get Twig Environment properly from the container, any idea about this?

[Kocal]

You can inject \Twig\Environment in your constructor.

@Kocal Not so easy for testing

@jmsche I'm not sure, but take a look at the class Symfony\Bundle\FrameworkBundle\Test\KernelTestCase and the service test.service_container. It might take a little work but I think it's a good lead.

[Kocal]

@maxhelias yes that's not really easy in fact, I'm already helping @jmsche on Symfony Slack and I think we will use the test.service_container.

Finally Travis is green :)

Many thanks to @Kocal who helped me a lot :)

Look good 👍

Just one small comment - I think I might be missing a detail. Thanks for this - it looks great!

[jmsche]

Updated PR by renaming test interface & fixing symfony/flex branch name in Travis config.

Travis is green again! :)

Thank you so much for this detailed work @jmsche!
