我只是想用我 3 个月前存储的相同命令来生成我的文件（我对后端和 devops 不太擅长），现在它不再生成文件了。它告诉我使用我不记得的删除命令，但即使使用该命令，我的文件仍然不会生成。这就是我的日志的样子，您可以在下面找到一个简单类的代码。
我的猜测之一是这与我更改 github 帐户有关，因为提到了权限问题。
我在 Windows 10 中使用 vs 代码。

我正在使用build_runner包构建一个代码生成器。
我运行flutter pub run build_runner build来执行我的代码生成器。
问题：
如何flutter pub run build_runner build使用断点进行调试？
类似问题：
如何在intellij idea中以调试模式运行flutter'packages pub run build_runner build'？
我想在我的生成器代码上放置断点，但我不知道如何在调试模式下运行该命令。
我使用source_gen和编写了生成器build_runner
class MyGenerator extends GeneratorForAnnotation<Todo> {
@override
FutureOr<String> generateForAnnotatedElement(
Element element, ConstantReader annotation, BuildStep buildStep) {
return "// Hey! Annotation found!";
}
}
运行后 flutter pub run build_runner watch --delete-conflicting-outputs

知道如何修复吗？我已经跑过很多次flutter pub get了pub get。
