The $entity_type parameter of EntityRouteProviderInterface::getRoutes() is deprecated

Overview

As of Drupal 11.4.0, the $entity_type parameter on EntityRouteProviderInterface::getRoutes() is deprecated. Route providers already receive the entity type on construction, so passing it again is redundant. Core no longer passes the argument; providers should read the entity type from the value injected on construction. The parameter is removed in drupal:13.0.0.

Changes

// Before.
public function getRoutes(EntityTypeInterface $entity_type) {
  // ...
}
$routes = $route_provider->getRoutes($entity_type);

// After.
public function getRoutes(?EntityTypeInterface $entity_type = NULL) {
  $entity_type = $entity_type ?? $this->entityType;
  // ...
}
$routes = $route_provider->getRoutes();
