Flutter是一种跨平台的移动应用开发框架,它使用Dart语言来构建高性能、美观的应用程序。在Flutter中,可以通过使用Flutter内置的json_annotation库和json_serializable库来对列表中的对象进行JSON解析。 具体步骤如下: 添加依赖:在Flutter项目的pubspec.yaml文件中,添加以下依赖: ...
json_annotation: ^2.4.0 dev_dependencies: fluttertoast: ^2.0.3 json_serializable: ^3.0.0 build_runner: ^1.6.0 创建Author实体类(举例子,新建文件author.dart) author.dart import 'package:json_annotation/json_annotation.dart'; part 'author.g.dart'; @JsonSerializable() //注解 class Author { St...
json_annotation: ^4.0.1 dev_dependencies: build_runner: ^2.1.5 json_serializable: ^4.1.3 然后,在需要解析JSON数据的Dart类上添加注解,指定需要生成的JSON序列化和反序列化的代码。例如,假设我们有一个名为User的类,包含了复杂的JSON数据结构: 代码语言:txt 复制 import 'package:json_annotation/json_annota...
我们要使用JsonSerializable生成代码的话必须要在需要生成代码的实体类前添加注解@JsonSerializable(),而要使用这个注解我们必须引入json_annotation/json_annotation.dart这个包。 import'package:json_annotation/json_annotation.dart';@JsonSerializable()classData{finalStringby;finalintdescendants;finalintid;finalList<int...
json_annotation: ^4.0.1 dev_dependencies: flutter_test: sdk: flutter build_runner: ^2.0.5 json_serializable: ^4.1.3 第二步: Importing import 'package:json_annotation/json_annotation.dart'; import 'package:build_runner/build_runner.dart'; ...
json_annotation: ^4.5.0 dev_dependencies: json_serializable: ^6.2.0 build_runner: ^2.1.11 1. 2. 3. 4. 5. 6. 二、手动创建模型类 import 'package:json_annotation/json_annotation.dart'; part 'user.g.dart'; @JsonSerializable()
json_annotation: ^2.4.0 dev_dependencies: fluttertoast: ^2.0.3 json_serializable: ^3.0.0 build_runner: ^1.6.0 首先我们需要创建用来解析或者转换成json的dart实体类 import 'package:json_annotation/json_annotation.dart'; part 'Author.g.dart'; ...
import'package:json_annotation/json_annotation.dart'; part 'person.g.dart';List<Person> getPersonList(List<dynamic> list){List<Person> result = []; list.forEach((item){ result.add(Person.fromJson(item)); });returnresult; }@JsonSerializable()classPersonextendsObjectwith_$PersonSerializerMixin...
