use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Sales\Setup\SalesSetupFactory;
use Magento\Quote\Setup\QuoteSetupFactory;

class InstallData implements InstallDataInterface
{
    /**
     * @var Magento\Sales\Setup\SalesSetupFactory
     */
    protected $_salesSetupFactory;

    /**
     * @var Magento\Quote\Setup\QuoteSetupFactory
     */
    protected $_quoteSetupFactory;

    /**
     * @param SalesSetupFactory $salesSetupFactory
     * @param QuoteSetupFactory $quoteSetupFactory
     */
    public function __construct(
        SalesSetupFactory $salesSetupFactory,
        QuoteSetupFactory $quoteSetupFactory
    ) {
        $this->_salesSetupFactory = $salesSetupFactory;

    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) {

        /** @var \Magento\Sales\Setup\SalesSetup $salesInstaller */
        $salesInstaller = $this->_salesSetupFactory
                        ->create(
                            [
                                'resourceName' => 'sales_setup',
                                'setup' => $setup
                            ]
                        );
        /** @var \Magento\Quote\Setup\QuoteSetup $quoteInstaller */
        $quoteInstaller = $this->_quoteSetupFactory
                        ->create(
                            [
                                'resourceName' => 'quote_setup',
                                'setup' => $setup
                            ]
                        );

        $this->addQuoteAttributes($quoteInstaller);
        $this->addOrderAttributes($salesInstaller);
    }

    /**
     * add attribute in quote address
     * @param object $installer
     */
    public function addQuoteAttributes($installer) {
        $installer->addAttribute('quote_address', 'attribute_name', ['type' => 'text']);
    }

    /**
     * add attribute in sales_order
     * @param object $installer
     */
    public function addOrderAttributes($installer) {
        $installer->addAttribute('order', 'attribute_name', ['type' => 'text']);
    }
}

here, salesInstaller and quoteInstaller is the instance of SalesSetup and QuoteSetup.
After that i have passed them on the function to create the attribute.
here, addQuoteAttributes function is responsible for create quote_address attribute and addOrderAttributes function is responsible for create order attribute.
here addAttribute function contains three parameters
first parameter is entity name.
second parameter is for name of your attribute.it can be anything according to need.
third parameter is for datatype of the attribute like here my attribute datatype is text.
Hope so it’ll help you.
