Code

public function getArgumentsResolver(RouteMatchInterface $route_match, AccountInterface $account, Request $request = NULL) {
  $route = $route_match
    ->getRouteObject();

  // Defaults for the parameters defined on the route object need to be added
  // to the raw arguments.
  $raw_route_arguments = $route_match
    ->getRawParameters()
    ->all() + $route
    ->getDefaults();
  $upcasted_route_arguments = $route_match
    ->getParameters()
    ->all();

  // Parameters which are not defined on the route object, but still are
  // essential for access checking are passed as wildcards to the argument
  // resolver. An access-check method with a parameter of type Route,
  // RouteMatchInterface, AccountInterface or Request will receive those
  // arguments regardless of the parameter name.

    $route,

    $account,
  ];
  if (isset($request)) {
    $wildcard_arguments[] = $request;
