Exports a single field item generically.

Any properties of the item that are explicitly marked non-exportable (which includes computed properties by default) will not be exported.

Field types that need special handling should provide a custom callback function to the exporter by subscribing to \Drupal\Core\DefaultContent\PreExportEvent.

Parameters

\Drupal\Core\Field\FieldItemInterface $item: The field item to export.

Return value

array The exported field values.
