How to get total cost and $valueFreeShipping inside file vendor/…/romcity/view/frontend/web/js/model/shipping-rates-validation-rules.js

Question

I don't want to load shipping method on City changed, if $valuePackage < $valueFreeShipping (because the shippinig cost in this case is zero)

How can I get these two values : $valuePackage(the total cart cost) and $valueFreeShipping (if total cart cost is greater than $valueFreeShipping , the shipping cost is zero) inside the file

vendor/..../romcity/view/frontend/web/js/model/shipping-rates-validation-rules.js ?

i need something like this

 if ($valuePackage < $valueFreeShipping) {
observableFields.push('city_id'); // Load shipping method on City_id changed
}

$valuePackage and $valueFreeShipping are not defined inside the file vendor/..../romcity/view/frontend/web/js/model/shipping-rates-validation-rules.js

Thank you!

in block:

public function getFreeShippingValue()
{
    return $this->scopeConfig->getValue('carriers/freeshipping/free_shipping_subtotal', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
}

in template:

$freeShipping = $block->getFreeShippingValue();

       <script>
           freeShipping = <?= /* @escapeNotVerified */ $freeShipping ?>;
       </script>

totals cart: in block:

private $cartHelper;
/**
 * Pricing helper.
 *
 * @var \Magento\Framework\Pricing\Helper\Data
 */
private $pricingHelper;
    \Magento\Checkout\Helper\Cart $cartHelper,
    \Magento\Framework\Pricing\Helper\Data $pricingHelper,
public function getCartHelper()
{
    return $this->cartHelper;
}
/**
 * Get pricing helper.
 *
 * @return \Magento\Framework\Pricing\Helper\Data
 */
public function getPricingHelper()
{
    return $this->pricingHelper;
}

in template

$quote = $block->getCartHelper()->getQuote();          
$total = $quote->getSubtotal();
