if (\Drupal::service('module_handler')->moduleExists('locale')) {
  // your code here
}

To solve this issue we can use a small, but a very useful module Route condition. This module provides condition plugin, which will display the block based on routes. Basically it works the same way as Pages condition plugin. So, I believe you will not find any issues configure it.
 

Let's imagine we have a node with field category and we want to create a link in the view and pass a category in the request ?field_category=1. Unfortunately, it will not like this by default. Fortunately, we have a solution! We need a module prepopulated and pass a parameter a special way:

1) For entity reference fields

2) Normal fields
