Get next incremental ID

Version

You can apply this model as a recipe (Drupal 10.3 or later) to your own Drupal site:

## Import recipe
composer require drupal-eca-recipe/eca_lib_0011

# Apply recipe with Drush (requires version 13 or later):
drush recipe ../recipes/eca_lib_0011

# Apply recipe without Drush:
cd web && php core/scripts/drupal recipe ../recipes/eca_lib_0011

# Rebuilding caches is optional, sometimes required:
drush cr
