I want to clear the cart before adding a new item to the cart.

I am trying to do using the event "checkout_cart_product_add_before" and by this code in the observer.

$allItems = $this->checkoutSession->getQuote()->getItemsCollection();

foreach ($allItems as $item) {
$itemId = $item->getItemId();

My all items getting remove from the cart with the newly added item also.

Can anyone help me out with this?



you can delete all item before they are adding as cart candidate. You can use following process

    $cart = $objectManager->create('\Magento\Checkout\Model\Cart');

    foreach ($cart->getQuote()->getAllItems() as $item) {
        /** @var \Magento\Quote\Model\Quote\Item $item */
    $cart->addProduct($newProduct, $request)->save();
