Fatal Error: Fatal error: Class 'Drupal\custom_avatar\CustomAvatarHtmlRouteProvider' not found in /Sites/drupal8/core/lib/Drupal/Core/Entity/EntityTypeManager.php on line 252
I am creating config Entity type and below is structure of my module shown in screenshot:
I below code I have defined below routing so that I don't have to define each of these routes statically in our module's routing.yml file. My class extends AdminHtmlRouteProvider :
"route_provider" = { "html" = "Drupal\custom_avatar\CustomAvatarHtmlRouteProvider", },
<?php
namespace Drupal\custom_avatar\Entity;
use Drupal\Core\Config\Entity\ConfigEntityBase;
/**

* "form" = {
* "add" = "Drupal\custom_avatar\Form\CustomAvatarForm",
* "edit" = "Drupal\custom_avatar\Form\CustomAvatarForm",
* "delete" = "Drupal\custom_avatar\Form\CustomAvatarFormDeleteForm"
* },
* "route_provider" = {
* "html" = "Drupal\custom_avatar\CustomAvatarHtmlRouteProvider",
* },
* },
* config_prefix = "custom_avatar",
* admin_permission = "administer site configuration",
* entity_keys = {
* "id" = "id",

* "uuid" = "uuid"

* "canonical" = "/admin/structure/custom_avatar/{custom_avatar}",
* "add-form" = "/admin/structure/custom_avatar/add",
* "edit-form" = "/admin/structure/custom_avatar/{custom_avatar}/edit",
* "delete-form" = "/admin/structure/custom_avatar/{custom_avatar}/delete",
* "collection" = "/admin/structure/custom_avatar"
* }

$route

// TitleResolver translates this string again.

Please suggest what is cause of error, the module gets installed without any error but when I clear all cache it shows error and the routs are not build using this way(page not found). I want to try using this class to build dynamic admin (canonical, add, edit, and delete forms for entities ) routs rather than defining in routing.yml
Thanks!
