Module development and code questions

Hi,

I've been working with my scss and css files.  I first started using a css file in order to check the styles on the website, but now I think I really should use scss files to create my css file, as I change things.

I added the scss files under the scss folder:  _main.scss and _fonts.scss

In the theme-custom-styles.scss file I added references:

I'm developing a module and I have a twig template being rendered by a theme.

I can't use the asset() function inside the twig template, because I always get a PHP error:

NOTICE: PHP message: Uncaught PHP Exception Twig\Error\SyntaxError: "Unknown "asset" function." at /app/web/modules/custom/my_module/templates/list-clients.html.twig line 6

I think I correctly installed symfony/asset using composer:

Using version ^5.2 for symfony/asset
 

What am I doing wrong here? Should I additionally configure symfony somewhere in Drupal installation?

I'm developing a module and a template is being rendered from modules/custom/my_module/src/templates/ directory.

However, the {{ directory }} variable inside twig points to 'core/themes/bartik' directory.

I suppose this is the parent theme.

How do I get the child theme path?
