除了转为 Dart 类型之外 , 其它 语言 类型 也可以转换 , https://www.bejson.com/json2javapojo/new/ 网站可以 JSON 转 JavaBean ; 推荐一个 JSON 转 Dart 的工具网站 : https://jsontodart.com/ 这是系统根据 JSON 字符串自动生成的 Dart 类 ; class A...

class Product{ String name; Product(this.name); } 使用dart:convert库把json字符串转成 Map<String,dynamic>对象,然后根据key把value取出,创建对象 import 'dart:convert'; import 'TechnologyCompany.dart'; void main() { var jsonStr = '''
您可以使用 dart:convert 库将 JSON 字符串转换为中间格式: 1import 'dart:convert';? 2 3try { 4??final parsed=json.decode(aJsonStr); 5} on FormatException catch (e) {? 6print("That string didn't look like Json."); 7} on NoSuchMethodError catch (e) {?
让我们为此json结构制作一个PODO(普通的旧式Dart对象?)文件。您可以在示例项目的student_model.dart中找到此代码。 class Student{ String studentId; String studentName; int studentScores; Student({ this.studentId, this.studentName,
String jsonString='''{"id":"123","name":"张三","score":95}''';final jsonResponse=json.decode(str);classStudent{String id;String name;String score;Student({this.id,this.name,this.score});factory Student.fromjson(data){Student stu=newStudent();stu.id=data['id'];stu.name=data['name...
