How can data parameters be passed to a factory create( ) in Magento 2?

Question

I have this snippet:

// In __constructor arguments:
\Magento\Framework\FlagFactory $flagFactory
...
// This is not called in __constructor:
$flag = $this->flagFactory->create(['flag_code' => 'something']);
var_dump($flag->getFlagCode());

It displays null. I var dumped into Magento\Framework\Flag::_construct() this var_dump($this->getData('flag_code')); exit; and still null.

Anyone has an ideea how to set a parameter in $data array of the create() function ? I'm in developer mode. The object manager factory would be Magento\Framework\ObjectManager\Factory\Dynamic::create

Answer 1

Use code like

$this->flagFactory->create(['data' => ['flag_code' => 'something']]);
