Calculates dependencies for field items.

Dependencies are saved in the field configuration entity and are used to determine configuration synchronization order. For example, if the field type's default value is a content entity, this method should return an array of dependencies listing the content entities.

Parameters

\Drupal\Core\Field\FieldDefinitionInterface $field_definition: The field definition.

Return value

array An array of dependencies grouped by type (config, content, module, theme). For example:

array(
  'config' => array(
    'user.role.anonymous',
    'user.role.authenticated',
  ),
  'content' => array(
    'node:article:f0a189e6-55fb-47fb-8005-5bef81c44d6d',
  ),
  'module' => array(
    'node',
    'user',
  ),
  'theme' => array(
    'seven',
  ),
);
