It seems like $socialiteUser->email() can also be of type null; however, parameter $email of App\Src\UseCases\Domain\User::__construct() does only seem to accept string, maybe add an additional type check?

        $picture = $this->handlePicture($socialiteUser);
        $user->create(null, $picture);

        // If the user has an email, we take it for granted that Google or Facebook has already verified it:
        $email = $socialiteUser->email();
        if (!empty($email))
            $this->userRepository->verifyEmail($id);

        return [
            'user_id' => $id,
            'provider_id' => $socialiteUser->providerId(),
        ];

    }
