Magento2 : How to override FinalPrice.php file in Magento2

Question

I want to override

vendor/magento/module-catalog/Pricing/Price/FinalPrice.php

with constructor argument.

Note : File overriding is working fine but when I create constructor in the overridden file it is giving me an error.

Answer 1

You need to pass parent constructor with your original class argument vendor/magento/module-catalog/Pricing/Price/FinalPrice.php

like

class A {
  public function __construct(Abc $abc){

  }
}

class B extends A {
  public function __construct(Abc $abc,Xyz $xyz){
      parent::__construct($abc);
  }
}
