How To make Seeder in fake data ?

Hello everyone! I having a bad time trying to use Seeder Fake data

My SettingSeeder

PHP Code:

<?php namespace App\Database\Seeds;
use App\Models\SettingModel;
use CodeIgniter\Database\Seeder;
use CodeIgniter\Test\Fabricator;
use Faker\Factory;

class SettingSeeder extends Seeder
{    
    public function run()
    {
        $faker = Factory::create();        
        $formatters = [
            'settingname' => $faker->name,
            'about_us'    => $faker->text,
            'mission'     => $faker->text,
            'vision'      => $faker->text,
        ];        
        $fabricator = new Fabricator(SettingModel::class, $formatters);
        $fabricator->create();
    }
