本文介绍Flutter中如何通过pubspect.yaml配置依赖库，包括CupertinoIcons、dio及json_annotation等，实现数据管理。并通过build_runner自动生成Dart代码，提升开发效率。文章还提供了命令行操作指导，解决可能遇到的冲突问题。

转发 Flutter 常用功能介绍
 Flutter第二部分（数据）
1.pubspect.yaml 添加如下代码后点击packages get
注意缩进不能变

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  dio: ^3.0.0
  json_annotation: ^3.0.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  build_runner: ^1.0.0
  json_serializable: ^3.2.0

2.生成dart文件
自动生成器
测试demo ,将生成的数据新建.dart文件放入lib目录下

{
      "status": 1,
      "data": {
        "pageData": {
          "pageNum": 1,
          "curPage": 1,
          "perPage": 10
        },
        "hosList": [
          {
            "id": 190,
            "name": "阜外医院",
            "illId": 1,
            "introduction": "北京阜外医院",
            "level": "三甲",
            "imgurl": "https://t.duodian.api.cheng1hu.com/attachment/hospital/2019/07/01/15/0c365acdfeb18bfc0806a7a922bee800.jpg"
          }
        ]
      }
    }

3.命令行二选一

flutter packages pub run build_runner build
flutter packages pub run build_runner watch
有冲突：flutter packages pub run build_runner build --delete-conflicting-outputs
