Flutter-Json转Dart类(VS)

库引用

pubspec.yaml 文件引入

dependencies:
  json_annotation: <最新版本>

dev_dependencies:
  build_runner: <最新版本>
  json_serializable: <最新版本>

终端运行

flutter packages get 

示例

已知Json数据,例如:

{
  "account":  "29_0",
  "pwd":  "29_0"
}

打开 https://caijinglong.github.io/json2dart/index.html ,将Json复制进去,将右侧代码附近到新建的dart文件中,注意dart文件名

保存文件后会提出错误,因为缺少引用文件,终端输入:

flutter packages pub run build_runner build

如遇到上述命令执行错误,可运行以下命令再试

flutter packages pub run build_runner clean
flutter packages pub run build_runner build --delete-conflicting-outputs

flutter clean
flutter doctor
flutter packages pub run build_runner clean
flutter packages pub run build_runner build --delete-conflicting-outputs
flutter packages pub run build_runner watch

 

注:

关于自动化生成model,可借助JSONConverter来实现
