How to set database path in eloquent connection method

I am getting problem with setting path to sqlite path database.

use Illuminate\Database\Capsule\Manager as Capsule;

$capsule = new Capsule();

$capsule->addConnection([
    'driver' => 'sqlite',
    'database' => './dbdata/db.sqlite',
]);

$capsule->setAsGlobal();
$capsule->bootEloquent();

File with this code and dbdata folder are on same path, so I tried adding ./dbdata/{name of sqlite file}, any help how to make connection with sqlite db? (This is out of the laravel)
