For the comment count you can get it in the node twig by:

{{ content.comment['#items'].comment_count }}

But the flag count i think there is no way to get it directly in the twig:
There is extension called flagcount in the flag module but it requires the flag object which is not available in node twig.
From comment section of flagcount callback function in flag/src/TwigExtension/FlagCount.php

   * Gets the number of flaggings for the given flag and flaggable.
   * @param \Drupal\flag\FlagInterface $flag
   *   The flag entity.
   * @param \Drupal\Core\Entity\EntityInterface $flaggable
   *   The flaggable entity.
   * @return string
   *   The number of times the flaggings for the given parameters.

So the only way is to pass by preprocess like the following:

 * Implements hook__preprocess_HOOK().
function YOURMODULE_preprocess_node(&$variables) {
  $node = $variables['elements']['#node'];
  // Set your flag id here.
  $flag_id = 'bookmark';
  $variables['flag_count'] = \Drupal::service('flag.count')->getEntityFlagCounts($node)[$flag_id];

And then in you twig you can do:

{{ flag_count }}

    Not sure, but you probably have to care about caching for the flag. Otherwise it won't increment unless you clear the cache. Maybe add the flag as #markup or #inline_template and let if have cache tagged with the nid and the flag id?

  • I managed to get the number of comments for a node with this code {{ node.field_article_commentaire.comment_count }} but it does not work with products. I tested this code and it returns nothing {{ product.field_produit_avis.comment_count }}

  • Did you check that the comment field in product is field_produit_avis ?
