here's my controller code:
use Magento\Framework\App\Filesystem\DirectoryList;
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Eav\Model\Config;

use Magento\Customer\Model\Customer;
class Save extends \Magento\Backend\App\Action
{
protected $idListing;
public function __construct(
CustomerSetupFactory $customerSetupFactory,
AttributeSetFactory $attributeSetFactory,
ModuleDataSetupInterface $setup,
ModuleContextInterface $contextt,
\Magento\Backend\App\Action\Context $context
) {
$this->customerSetupFactory = $customerSetupFactory;
$this->attributeSetFactory = $attributeSetFactory;
$this->setup =$setup;
parent::__construct($context);
}
private function saveAttribute(){
$context = $this->contextt;
$setup = $this->setup;
$customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
$customerEntity = $customerSetup->getEavConfig()->getEntityType('customer');
$attributeSetId = $customerEntity->getDefaultAttributeSetId();
/** @var $attributeSet AttributeSet */
$attributeSet = $this->attributeSetFactory->create();
$attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);
$customerSetup->addAttribute(Customer::ENTITY, 'test1234', [
'type' => 'varchar',
'label' => 'test',
'input' => 'text',
'required' => false,
'visible' => true,
'user_defined' => true,

$attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'test1234')
->addData([
'attribute_set_id' => $attributeSetId,
'attribute_group_id' => $attributeGroupId,

try {
$attribute->save();
echo "success";
} catch (Exception $e) {
print_r($e->getMessage());
