Magento 2 como exibir os métodos de envio ordenados por preço?

Question

Olá, gostaríamos de classificar e exibir os métodos de envio por preço de baixo para alto na página de checkout.

Por exemplo:

$31.72 Express Saver Federal Express $37.50  2 DayFederal Express
$80.47 Standard Overnight Federal Express $87.77  Priority Overnight Federal Express
$5.00 Fixed Flat Rate $5.00   Media Mail Select Shipping Method
$10.00  FedEx Home Delivery Select Shipping Method

Referindo-me a este conceito de plugin tentando mudar minha saída usando plugin. Magento 2: oculte outros métodos de envio quando o frete grátis estiver disponível

<?php
namespace Demo\Test\Plugin\Model;
use Magento\Framework\Session\Generic;


class ShippingMethodManagement {

    /**
     * @var Generic
    */
    private $coreSession;

    /**
     * @param \Magento\Framework\Session\Generic $sessionManager */ public function __construct( Generic $sessionManager
    ) {
        $this->coreSession = $sessionManager;    
    }

    public function afterEstimateByExtendedAddress($shippingMethodManagement, $output)
    {
        return $this->filterOutput($output);
    }
    public function afterEstimateByAddress($shippingMethodManagement, $output)
    {
        return $this->filterOutput($output);
    }
    public function afterEstimateByAddressId($shippingMethodManagement, $output)
    {
        return $this->filterOutput($output);
    }
    private function filterOutput($output) { //Here i would like to sort shipping methods by shipping amount $all = [];
        
            foreach ($output as $shippingMethod) {               

                $all[] = $shippingMethod;
            } 

            return $all;
        } 
    }
}

Answer 1

A lógica abaixo funciona para mim.

    <?php
    namespace Demo\Test\Plugin\Model;
    use Magento\Framework\Session\Generic;
    
    
    class ShippingMethodManagement {
    
        /**
         * @var Generic
        */
        private $coreSession; /** * @param \Magento\Framework\Session\Generic $sessionManager
        */
        public function __construct(
            Generic $sessionManager ) { $this->coreSession = $sessionManager; } public function afterEstimateByExtendedAddress($shippingMethodManagement, $output) { return $this->filterOutput($output); } public function afterEstimateByAddress($shippingMethodManagement, $output) { return $this->filterOutput($output); } public function afterEstimateByAddressId($shippingMethodManagement, $output) { return $this->filterOutput($output); } private function filterOutput($output)
        {
           //Here i would like to sort shipping methods by shipping amount
         
            $all = []; foreach ($output as $shippingMethod) { $all[$shippingMethod->getAmount()] = $shippingMethod;
                } 
                ksort($all); return $all;
          } 
        
    }

Answer 2

Não tenho certeza de como o atributo de custo de envio seria chamado (pode ser necessário depurar), no entanto, supondo que seja 'preço', isso deve funcionar. Adicione isto acima do retorno:

usort($all, function($a,$b){ return $a->price > $b->price; }); return $all;
