flutter - 如何正确构建.yaml？

Question

我刚开始学习 Flutter。我使用 vscode 作为编辑器

我需要在我的代码上使用 json_serializable。我阅读了https://pub.dev/packages/json_serializable并让我的 build.yaml 就像那里显示的一样。

targets:
  $default:
    builders:
      json_serializable:
        options:
          # Options configure how source code is generated for every
          # `@JsonSerializable`-annotated class in the package.
          #
          # The default value for each is listed.
          any_map: false
          checked: false
          constructor: ""
          create_factory: true
          create_to_json: true
          disallow_unrecognized_keys: false
          explicit_to_json: false
          field_rename: none
          generic_argument_factories: false
          ignore_unannotated: false
          include_if_null: true

但是 vscode 说：不允许使用属性目标。yaml 架构：Hammerkit YAML 架构 [1,1]

仅供参考，这是我的 pubspec.lock

所以请告诉我如何为颤振编写正确的 build.yaml。

注意：我需要将 explicit_to_json 值更改为 true

Answer 1

您需要为 dart 构建系统 build.yaml 文件添加一个有效的 JSONSchema，或者禁用它，但我不知道如何在 VSCode 上执行此操作，因为我不使用它。

有效的 Dart 构建系统 JSONSchema 可从schemastore.org 获得，搜索页面Dart build configuration并从中获取链接 - 在此答案时，链接为https://json.schemastore.org/dart-build.json。

要将有效架构添加到 VSCode，您首先需要安装redhat.vscode-yaml扩展，然后将下面的块添加到您的设置中。

"yaml.schemas": {
  "https://json.schemastore.org/dart-build.json": [
    "build.yaml"
  ]
},

归功于：@simolus3 获取上述有关如何将架构添加到来自此链接的 vscode 的信息。注意：上面的代码片段在回答时使用了正确的 URL。
