[英]Dart parse nested map json

问题描述

I would like to map each of the attributes eg cashAndShortTermInvestments, accountsReceivable from below site in a Model class when parsing the json.我想在解析 json 时映射模型类中的每个属性，例如 cashAndShortTermInvestments、accountReceivable 从下面的站点。 Below are my codes and it doesn't seem to work.下面是我的代码，它似乎不起作用。 Appreciate if someone could help point where my codes are wrong and how it should be corrected.感谢有人可以帮助指出我的代码错误的地方以及应该如何更正。

Site: https://dev.last10k.com/docs/services/53c7e3aafd2dff034f040002/operations/5e2a9d30c8fa8071c307f0e2 ?网站： https : //dev.last10k.com/docs/services/53c7e3aafd2dff034f040002/operations/5e2a9d30c8fa8071c307f0e2 ?

Thank you very much in advance!非常感谢您提前！

i found the issue.. i should have done below for each attribute in factory RatiosModel constructor我发现了这个问题.. 我应该为工厂 RatiosModel 构造函数中的每个属性做以下操作

cashAndShortTermInvestments: Financial.fromJson(json["CashAndShortTermInvestments"]),

also, i have changed the parameter of the factory constructor to (dynamic json)另外，我已将工厂构造函数的参数更改为（动态 json）

i also corrected below in factory Financial.fromJson(dynamic json)我还在下面的工厂 Financial.fromJson(dynamic json) 中更正了

historical: Map.from(json['Historical']).map((k, v) =>
          MapEntry<String, double>(k, v)),

category: Map.from(json['Category']).map((k, v) =>
          MapEntry<String, String>(k, v)),


class Financial {
  String name;
  Map<String, double> historical;
  Map<String, double>? recent;
  Map<String, String> category;

  Financial({
    required this.name,
    required this.historical,
    this.recent,
    required this.category,
  });

  factory Financial.fromJson(dynamic json) {
    return Financial(
      name: json['Name'],
      historical: Map.from(json['Historical']).map((k, v) =>
          MapEntry<String, double>(k, v)),
