원가계산기 : 승민님 코드 읽기

승민님의 원가계산기 코드를 보고 원가계산기를 만들 생각이다. 

 

승민님의 재료 모델 클래스 

 

생성되는 날짜의 변수 값을 dynamic

 

class DtoIngredient {
  dynamic createdDate;
  String? ingredientName;
  double? weight;
  double? price;
  String? brand;
  double? inputUnit;
  double? pricePerGram;
  double? totalPrice;
  String? id;

  DtoIngredient(
      {required this.createdDate,
      required this.ingredientName,
      required this.weight,
      required this.price,
      required this.brand,
      required this.inputUnit,
      required this.pricePerGram,
      required this.totalPrice,
      this.id});

  DtoIngredient.fromJson(Map<String, dynamic> json, String? _id)
      : createdDate = json['createdDate'],
        ingredientName = json['ingredientName'],
        weight = json['weight'],
        price = json['price'],
        brand = json['brand'],
        inputUnit = json['inputUnit'],
        pricePerGram = json['pricePerGram'],
        totalPrice = json['totalPrice'],
        id = _id;

  Map<String, dynamic> toJson() => {
        'createdDate': createdDate,
        'ingredientName': ingredientName,
        'weight': weight,
        'price': price,
        'brand': brand,
        'inputUnit': inputUnit,
        'pricePerGram': pricePerGram,
        'totalPrice': totalPrice,
      };
}

 

 

소스에 들어가는 메뉴 클래스 

import 'package:flutter/material.dart';

import 'dto_ingredient.dart';

class DtoSauce {
  String? createdAt;
  String? lastUpdatedDate;
  String? sauceName;
  double? totalWeight;
  double? pricePerGram;
  double? totalPrice;
  String? id;

  DtoSauce(
      {required this.createdAt,
      required this.lastUpdatedDate,
      required this.sauceName,
      required this.totalWeight,
      required this.pricePerGram,
      required this.totalPrice,
      this.id,});

  DtoSauce.fromJson(Map<String, dynamic> json,String _id)
      : createdAt = json['createdAt'],
        lastUpdatedDate = json['lastUpdatedDate'],
        sauceName = json['sauceName'],
        totalWeight = json['totalWeight'],
        pricePerGram = json['pricePerGram'],
        totalPrice = json['totalPrice'],
  id = _id;


  Map<String, dynamic> toJson() => {
        'createdAt': createdAt,
        'lastUpdatedDate': lastUpdatedDate,
        'sauceName': sauceName,
        'totalWeight': totalWeight,
        'pricePerGram': pricePerGram,
        'totalPrice': totalPrice,
      };
}

 

메뉴 클래스 -> 이 안에 소스 메뉴의 리스트를 넣어놨다. 

이러면 후에 메뉴를 만들 때 소스 메뉴를 선택 할 수 있게 된다. 

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';

class DtoMenu {
  Timestamp? createdAt;
  Timestamp? lastUpdatedDate;
  String? menuName;
  double? totalWeight;
  double? pricePerGram;
  double? totalPrice;
  int? ingredientQuantity;
  String? id;
  List<String>? sauceIdList;

  DtoMenu(
      {required this.createdAt,
      required this.lastUpdatedDate,
      required this.menuName,
      required this.totalWeight,
      required this.pricePerGram,
      required this.totalPrice,
      required this.ingredientQuantity,
      this.id,
      this.sauceIdList});

  DtoMenu.fromJson(Map<String, dynamic> json)
      : createdAt = json['createdAt'],
        lastUpdatedDate = json['lastUpdatedDate'],
        menuName = json['menuName'],
        totalWeight = json['totalWeight'],
        pricePerGram = json['pricePerGram'],
        totalPrice = json['totalPrice'],
        ingredientQuantity = json['ingredientQuantity'],
        sauceIdList = json['sauceIdList'];

  Map<String, dynamic> toJson() => {
        'createdAt': createdAt,
        'lastUpdatedDate': lastUpdatedDate,
        'menuName': menuName,
        'totalWeight': totalWeight,
        'pricePerGram': pricePerGram,
        'totalPrice': totalPrice,
        'ingredientQuantity': ingredientQuantity,
        'sauceIdList': sauceIdList,
      };
}
