How do I get the estimate shipping Country id in Magento 2?

Question

I am writing a custom shipping rates module, and I can’t seem to figure out how to get the estimate shipping Country ID.

I know how to get the Country id once the order has been created, but not for the estimate shipping portion of the checkout process

Any input is greatly appreciated!

For Magento 1.9 I used this

Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress()->getData('country_id')

Or

Mage::getSingleton('checkout/session')->getQuote()->getBillingAddress()->getData('country_id'); 

Answer 1

An interest fact about Magento2 That magento2 does not save shipping address address and billing address to quote until click on Place Order button at frontend.

Save Process

If you will check at database table quote_address during checkout,then you can understand.. Basically at browser local storage,Magento save shipping and billing address and save during click on place Order .

If you Digg on shipping estimation then you can understand that magento only need address attribute field country_id,region,region_id,city etc need for calculate the shipping rates .

At frontend checkout,Magento send address fields value from existing address or newly created address.

Magento 2.3.5

 private $cart;

public function __construct(
    \Magento\Checkout\Model\Cart $cart
) {
    $this->cart = $cart;
} 

public function ()
{
   
    $estimated_country = $this->cart->getQuote()->getShippingAddress()->getCountryId();
}

Inject \Magento\Checkout\Model\Session in your constructor.

/**
 * @var \Magento\Checkout\Model\Session
 */
protected $_checkoutSession;

public function __construct(
    \Magento\Checkout\Model\Session $checkoutSession
)
{
    $this->_checkoutSession = $checkoutSession;

}

And then, we can get:

 $this->_checkoutSession->getQuote()->getShippingAddress()->getCity();
 $this->_checkoutSession->getQuote()->getShippingAddress()->getCountryId();
 $this->_checkoutSession->getQuote()->getBillingAddress()->getCountryId();

UPDATE:

For the estimation shipping country, we can try:

/** @var \Magento\Quote\Api\Data\EstimateAddressInterface $estimatedAddress */
$estimatedAddress->getCountryId();

Instead of checkout session, I think you have to use checkout Cart

    protected $_checkoutCart;

    public function __construct(
        \Magento\Checkout\Model\Cart $checkoutCart
    )
    {
        $this->_checkoutCart = $checkoutCart;

    }

And Then :

    $this->_checkoutCart->getQuote()->getShippingAddress()->getData();
