Flutter Dart 分析器不应用我的 linter 规则

Flutter Dart analyzer not applying my linter rules

我正在做一个非常标准的 Flutter 项目。因为我是 Flutter 和 Dart 的新手,所以我希望我的工具尽可能有用。所以我把 pedantic: ^1.9.0 添加到 dev_dependencies 并这样写 analysis_options.yaml

include: package:pedantic/analysis_options.yaml

analyzer:
  exclude: [build/**]
  strong-mode:
    implicit-casts: false
    implicit-dynamic: false

根据 https://dart-lang.github.io/linter/lints/pedantic 应该启用 avoid_empty_elseavoid_relative_lib_imports lints,作为错误。但是当我写这样的代码时:

import '../model/model.dart';

或者这个:

  if (context == null) {
    print('context is null');
  } else {
  }

我在 IntelliJ IDEA 中没有收到任何错误,手动 运行 flutter analyze 时也没有收到任何错误:

$ flutter analyze
Analyzing app...                                                        
No issues found! (ran in 5.0s)

我已尝试明确启用这些 lints:

linter:
  rules:
    - avoid_empty_else
    - avoid_relative_lib_imports

这没有任何区别。

我尝试向该列表添加一个不存在的 lint foo 以验证该文件是否正在使用,它是:

$ flutter analyze
Analyzing app...                                                        

warning • 'foo' is not a recognized lint rule • analysis_options.yaml:12:7 • undefined_lint_warning

1 issue found. (ran in 4.9s)

我什至尝试 运行直接从 Flutter 安装目录中安装 dartanalyzer,使用我能找到的所有详细选项:

$ ~/flutter/bin/cache/dart-sdk/bin/dartanalyzer --lints --verbose --log --options analysis_options.yaml .
Analyzing app...
Loaded analysis options from analysis_options.yaml
Analysis options: lints = true
No issues found!

为了完整起见,这是我的医生输出:

我还应该做些什么来让 linter 工作吗?

啊,所以... linter 工作正常;只是我的假设被打破了。

avoid_empty_else 不检查空的 {} 块,而只检查 else 之后的 ;,这就是它没有触发的原因。

avoid_relative_lib_imports literally only checks 用于路径名称中包含 /lib/ 的相对导入,不适用于其目标解析为 lib/.[=19 中的某个文件的相对导入=]

无赖。我希望完全禁止相对导入,但是 that's still unimplemented.
