How to change page title of Manage Fields screen based on bundle name? Is it possible to change admin screen page title based on bundle related to the screen. For example, I would like title of admin/structure/types/manage/datasheet/fields page to be Manage datasheet fields. Is it possible?
You need to replace the static title with a dynamic title.

Reference: https://www.drupal.org/node/2067859

This describes how to define dynamic titles for new routes in yaml files. You need to change the existing route entity.node.field_ui_fields in a route subscriber:

$route-&gt;setDefault('_title_callback', '\Drupal\mymodule\Controller\MyController::getTitle');
