Unknown "svg" function

[dubitoph]

I'm using Symfony 5.1 and I just have updated Twig from 2.14.1 to 3.1.1.

There is my configuration in "config\services.yaml" to use this extension :

...
services:
...
    manuelodelain\Twig\Extension\SvgExtension:
        class: manuelodelain\Twig\Extension\SvgExtension

I get this error : Unknown "svg" function.

I reinstalled twig/extensions with all dependencies and it works. But, the Twig version was downgraded to 2.14.1 and I have 2 alerts :

Package doctrine/reflection is abandoned, you should avoid using it. Use roave/better-reflection instead. Package twig/extensions is abandoned, you should avoid using it. No replacement was suggested.

This package doesn't require either of those packages as dependencies, so I'd guess that another package you have is requiring those. Check with these commands:

composer why doctrine/reflection composer why twig/extensions

That will tell you the dependency tree for those packages.

Ok, thank you for your help.

Effectively, it isn't this extension has need to doctrine/refection and twig/extensions :

doctrine/common 2.13.3 requires doctrine/reflection (^1.0) doctrine/persistence 1.3.8 requires doctrine/reflection (^1.2) dev-master requires twig/extensions (^1.5)

However, when I remove twig/extensions, svg function isn't recognized by Twig.
