Getting General error : '"mysqldump"' is not recognized as an internal or external command in laravel

Getting General error : '"mysqldump"' is not recognized as an internal or external command in laravel while run the following command.

php artisan backup:run

I did this in config/database.php file

 'dump' => [
    'dump_binary_path' => 'C:/xampp/mysql/bin/', // only the path, so without `mysqldump` or `pg_dump`
    'use_single_transaction',
    'timeout' => 60 * 5, // 5 minute timeout
 ],

but no success still getting the same error. please help!
