Fatal error: Class App\Entity\User contains 1 abstract method and must therefore be declared abstract

Problème

Après avoir exécuté la commande

symfony console make:user

Vous obtenez l'erreur

Fatal error: Class App\Entity\User contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Symfony\Component\Security\Core\User\UserInterface::getUsername)

Solution possible

/**
 * A visual identifier that represents this user.
 *
 * @see UserInterface
 */
public function getUsername(): string
{
    return (string) $this->email;
}
