在开发过程中,我们一般都是使用插件或工具一键生成实体类的,这样极大的提高了开发效率,目前我们可以通过在线生成的方式来一键生成Dart类。1. 使用json_to_dart地址:https://javiercbk.github.io/json_to_dart/首先打开json_to_dart页面如下:json_to_dart界面 将json数据赋值到输入框中,点击 ...
import'dart:convert'; import'package:json_annotation/json_annotation.dart'; part'example.g.dart'; @JsonSerializable() classPersons{ List<Person> persons; Persons() {} factoryPersons.fromJson(Map<String,dynamic> json) => _$PersonsFromJson(json); Map<String,dynamic> toJson() => _$PersonsTo...
JSON转换成Dart对象 假设请求的返回的JSON数据如下 {“id" : 12345, "title" : "titleName"} 1. 对应的dart对象 class Article { final String title; // dynamic表示不知道传进去什么类型 Artilce.fromJson(Map<String, dynamic> json) { id = json['id']; ...
built_value_generator: 准备json数据 { "id":157538, "date":"2017-07-21T10:30:34", "date_gmt":"2017-07-21T17:30:34", "type":"post", "link":"https://example.com", "title":{ "rendered":"Json 2 dart built_value converter" ...
新建⼯程，选择 Dart -> Dart Command Line App, 输⼊ Dart SDK 路径，然后点击 Next，输⼊⼯程名 example，完成向导。添加依赖 在 pubspec.yaml 的 dependencies 部分添加依赖 dependencies:json_annotation: ^3.0.0 analyzer: '0.39.14'点击⽂件上⽅的 Pub get 链接下载依赖 Dart example.dart ...
part of 'user.dart'; // *** // JsonSerializableGenerator // *** User _$UserFromJson(Map<String, dynamic> json) { return User( name: json['name'] as String, lastName: json['lastName'] as String, add: json['add'] as String, subscription: json['subscription'...
输入完这个命令之后,就会生成一个user.g.dart文件,在user.dart同级目录之中,代码如下: // GENERATED CODE - DO NOT MODIFY BY HANDpart of 'user.dart';// ***// JsonSerializableGenerator// ***User _$UserFromJson(Map<String, dynamic> json) {return User(name: json['name'] as String...
代码的实现很简单,首先看 bin 下的示例,通过@Model()将GetUsersResponse和User声明为 JSON 对象,然后在运行时,宏编程会自动添加fromJson和toJson方式。 import'dart:convert';import'package:macros/model.dart';@Model()classUser{User({requiredthis.username,requiredthis.password,});finalStringusernam...
