Symfony 6 fixtures UserPasswordHasherInterface

Question

How can we use UserPasswordHasherInterface in a fixture to create users in Symfony 6?

//App/DataFixtures/AppFixtures.php

namespace App\DataFixtures;

use App\Entity\User;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;

class AppFixtures extends Fixture
{
    private $manager;

    public function load(ObjectManager $manager, UserPasswordHasherInterface $userPasswordHasherInterface): void
    {
        $this->manager = $manager;

        $user = new User();
        $user->setEmail("test@example.com");
        //$user->setPassword("test_pass");
        $user->setPassword(
            $userPasswordHasherInterface->hashPassword(
                $user, "test_pass"
            )
        );

        $user->setFirstName("Fixture First 1");
        $user->setLastName("Fixture Last 1");

        $this->manager->persist($user);
        $this->manager->flush();
    }
}

Error returned

You need to inject UserPasswordHasherInterface in a constructor , like this:

//App/DataFixtures/AppFixtures.php

namespace App\DataFixtures;

use App\Entity\User;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;

class AppFixtures extends Fixture
{
    private $userPasswordHasherInterface;

    public function __construct (UserPasswordHasherInterface $userPasswordHasherInterface) 
    {
        $this->userPasswordHasherInterface = $userPasswordHasherInterface;
    }

    public function load(ObjectManager $manager): void
    {
        $user = new User();
        $user->setEmail("test@example.com");
        //$user->setPassword("test_pass");
        $user->setPassword(
            $this->userPasswordHasherInterface->hashPassword(
                $user, "test_pass"
            )
        );

        $user->setFirstName("Fixture First 1");
        $user->setLastName("Fixture Last 1");

        $manager->persist($user);
        $manager->flush();
    }
}
