Parameters

array $default_value: The unprocessed default value defined for the field, as a numerically indexed array of items, each item being an array of property/value pairs.

\Drupal\Core\Entity\FieldableEntityInterface $entity: The entity for which the default value is generated.

\Drupal\Core\Field\FieldDefinitionInterface $definition: The definition of the field.

Return value

array The return default value for the field.
