I installed a module quizzard and after uninstallation I am getting this error

Uncaught PHP Exception Symfony\Component\Routing\Exception\RouteNotFoundException: "Route "quizard.quizard_config_form" does not exist." at /home/paddu008/public_html/core/lib/Drupal/Core/Routing/RouteProvider.php line 190

So how do I rebuild route cache programmatically.

If you would like to clear route cache programmatically in drupal 8, use the following:

  • This can be run from the command line as drush eval '\Drupal::service("router.builder")->rebuild();'

On Exact Cases such as hook_preprocess_pager(&$variables) {...

You can also use

$variables['#cache']['max-age'] = 0; \Drupal::service('page_cache_kill_switch')->trigger(); cache_clear_all() // For Drupal-7 drupal_flush_all_caches() // For Drupal-8
