[英]Flutter Dart analyzer not applying my linter rules
I'm working on a pretty standard Flutter project.我正在做一个非常标准的 Flutter 项目。 Because I'm new to Flutter and Dart, I'd like my tools to be as helpful as possible.因为我是 Flutter 和 Dart 的新手,所以我希望我的工具尽可能有用。 So I added pedantic: ^1.9.0
to dev_dependencies
and wrote analysis_options.yaml
like this:所以我添加pedantic: ^1.9.0
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
According to https://dart-lang.github.io/linter/lints/ , pedantic
should enable the avoid_empty_else
and avoid_relative_lib_imports
lints, among others, as errors.根据https://dart-lang.github.io/linter/lints/ , pedantic
应该启用avoid_empty_else
和avoid_relative_lib_imports
lints,作为错误。 But when I write code like:但是当我编写如下代码时:
import '../model/model.dart';
or this:或这个:
if (context == null) {
print('context is null');
} else {
}
I'm not getting any errors in IntelliJ IDEA, nor when I run flutter analyze
manually: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)
I've tried enabling these lints explicitly:我已经尝试明确启用这些 lints:
linter:
rules:
- avoid_empty_else
- avoid_relative_lib_imports
This doesn't make any difference.这没有任何区别。
I've tried adding a nonexistent lint foo
to that list to verify that the file is being used, and it is:我已经尝试在该列表中添加一个不存在的 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)
I even tried running the dartanalyzer
from the Flutter installation directory directly, with all verbosity options that I could find:我什至尝试直接从 Flutter 安装目录运行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!
For completeness, here's my doctor output:为了完整起见,这是我的医生 output:

Is there something else I should do to get the linter to work?我还应该做些什么来让 linter 工作吗?
Ah, so... the linter is working fine;啊,所以... linter 工作正常; it was just my assumptions that were broken.只是我的假设被打破了。
avoid_empty_else
does not check for empty {}
blocks, but only for ;
avoid_empty_else
不检查空的{}
块,但只检查;
right after else
, which is why it didn't trigger.就在else
之后,这就是它没有触发的原因。
avoid_relative_lib_imports
literally only checks for relative imports whose path contains /lib/
in the name, not for relative imports whose target resolves to some file inside lib/
. avoid_relative_lib_imports
从字面上只检查名称中路径包含/lib/
的相对导入,而不检查其目标解析为lib/
内某个文件的相对导入。
Bummer.无赖。 I was hoping to forbid relative imports altogether, but that's still unimplemented .我希望完全禁止相对导入,但仍未实现。
