I am using Drupal commerce 2.x which is based on Drupal 8. I want to access store detail like store name,email programmatically in my custom module.
First you need to load the store object:
$entity_manager = \Drupal::entityManager();
$store = $entity_manager->getStorage('commerce_store')->loadDefault();
$mail = $store->getEmail();
$name = $store->getName();
If you have more than one store:
$store_id = 1;
$store = \Drupal\commerce_store\Entity\Store::load($store_id);
