I configured this in services.yaml

    service.crud:
        class: Common\Crud
        arguments: ["@services.wrap"]

this is written in the code

$this->crud = $this->get("service.crud");
$this->crud->test();

now if you want to jump to the code, click test () to jump to the class file Common\ Crud.php corresponding to the method test ()
