配合第三方
json_annotation处理To use package:json_serializable in your package, add these dependencies to your
pubspec.yaml. -
使用方法
python3 ${py脚本路径} ${json文件路径} ${初始类名} -
源文件
{
"name": "BeJson",
"url": "http://www.bejson.com",
"page": 88,
"isNonProfit": true,
"address": {
"street": "科技园路.",
"city": "江苏苏州",
"country": "**"
},
"links": [
{
"name": "Google",
"url": "http://www.google.com"
},
{
"name": "Baidu",
"url": "http://www.baidu.com"
},
{
"name": "SoSo",
"url": "http://www.SoSo.com"
}
]
}
- 结果：
import 'package:json_annotation/json_annotation.dart';
part 'TestBean.g.dart';
@JsonSerializable()
class TestBean {
String name;
String url;
int page;
bool isNonProfit;
AddressBean address;
List<LinksBean> links;
TestBean(
this.name,
this.url,
this.page,
this.isNonProfit,
this.address,
this.links,
);
factory TestBean .fromJson(Map<String, dynamic> json) =>
_$ TestBean FromJson(json);
Map<String, dynamic> toJson() => _$ TestBean ToJson(this);
}
@JsonSerializable()
class AddressBean {
String street;
String city;
String country;
AddressBean(
this.street,
this.city,
this.country,
);
factory AddressBean .fromJson(Map<String, dynamic> json) =>
_$ AddressBean FromJson(json);
Map<String, dynamic> toJson() => _$ AddressBean ToJson(this);
}
@JsonSerializable()
class LinksBean {
String name;
String url;
LinksBean(
this.name,
this.url,
);
factory LinksBean .fromJson(Map<String, dynamic> json) =>
_$ LinksBean FromJson(json);
Map<String, dynamic> toJson() => _$ LinksBean ToJson(this);
}
-
将
TestBean、AddressBean、LinksBean更换为开发需要的名称 -
以下方法中故意保留了一个空格符，需要去掉，也可以在源码中自己去掉。
factory TestBean .fromJson(Map<String, dynamic> json) =>
_$ TestBean FromJson(json);
Map<String, dynamic> toJson() => _$ TestBean ToJson(this);
- 按需要执行相关的操作
flutter packages pub run build_runner build
flutter packages pub run build_runner watch
//删除旧文件
flutter packages pub run build_runner build --delete-conflicting-outputs
- 当前为测试版本，常见的
json格式可以正常解析，如果报异常错误，请把json和报错信息提交Issues
