对 js/ts 的启发

0x01

0x02

typescript 中 class 数组，从远程获取数据的初始化

理想中的 Class List

final mockHeroes = <Hero>[
  Hero(2, 'sad'),
  Hero(11, 'Mr. Nice'),
  Hero(12, 'Narco'),
  Hero(13, 'Bombasto'),
  Hero(14, 'Celeritas'),
  Hero(15, 'Magneta'),
  Hero(16, 'RubberMan'),
  Hero(17, 'Dynama'),
  Hero(18, 'Dr IQ'),
  Hero(19, 'Magma'),
  Hero(20, 'Tornado')
];

后台实际返回的数据

[
  { "id": 11, "name": "Mr. Nice" },
  { "id": 12, "name": "Narco" },
  { "id": 13, "name": "Bombasto" },
  { "id": 14, "name": "Celeritas" },
  { "id": 15, "name": "Magneta" },
  { "id": 16, "name": "RubberMan" },
  { "id": 17, "name": "Dynama" },
  { "id": 18, "name": "Dr IQ" },
  { "id": 19, "name": "Magma" },
  { "id": 20, "name": "Tornado" }
]

不推荐写法

ts

// bad
public heroes: Heroes[] = [];

getHeroes{
    this.service.getHeroes().subscribe(
      res => {
        this.heroes = [...res];
      });
}

此时的 heroes 中的元素的类型不是 Heroes

推荐写法

dart

// good

// service
  Future<List<Hero>> getAll() async {
    try {
      final response = await _http.get(_heroesUrl);
      final heroes = (_extractData(response) as List)
          .map((json) => Hero.fromJson(json))
          .toList();
      return heroes;
    } catch (e) {
      throw _handleError(e);
    }
  }
// hero.dart
class Hero {
  final int id;
  String name;

  Hero(this.id, this.name);

  factory Hero.fromJson(Map<String, dynamic> hero) =>
      Hero(_toInt(hero['id']), hero['name']);

  Map toJson() => {'id': id, 'name': name};
}

int _toInt(id) => id is int ? id : int.parse(id);

ts

// good
