How to programmatically get list of available image styles I'm able to get a list of fields using

$fields = array_keys(\Drupal::entityManager()-&gt;getFieldDefinitions('node', 'ce_meeting'));


But is there a way to get a list of Image Styles instead?
Something similar to

$fields = array_keys(\Drupal::entityManager()-&gt;getImageStyles());


to spit out an array

['thumbnail','original','medium','large','small']


Is there a function to display a list of available image styles?
use 

use Drupal\image\Entity\ImageStyle;


and load all image style with 

$styles = ImageStyle::loadMultiple();


Also you can use  entity_load_multiple  with

 styles = \Drupal::entityTypeManager()-&gt;getStorage('image_style')-&gt;loadMultiple();
