    Metadata details:
    filename: subscription_line_items_controller.rb

    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'open_food_networ
    
    def price_estimate
      return unless @order_cycle

      fee_calculator = OpenFoodNetwork::EnterpriseFeeCalculator.new(@shop, @order_cycle)
      OpenFoodNetwork::ScopeVariantToHub.new(@shop).scope(@variant)
      @variant.price + fee_calculator.indexed_fees_for(@variant)
    end
