请问一下，我有一个测试的git项目：
/Git-Test/
在此目录下有.gitignore 文件：
/Git-Test/.gitignore在下面有多个测试项目，比如：
/Git-Test/react-test/react-proj-01/
/Git-Test/react-test/react-proj-01/
/Git-Test/flutter-test/flutter-proj-01/
/Git-Test/flutter-test/flutter-proj-02/我的/Git-Test/.gitignore文件为：
### Flutter ###
# Flutter/Dart/Pub related

###请见，比如里面的配置：build/ ，是指的/Git-Test/此目录下的build/没错吧，
但是我commit 提交公共库之后，在如下目录下：
/Git-Test/flutter-test/flutter-proj-01/
/Git-Test/flutter-test/flutter-proj-02/的build/都是没有被追踪的。
当然这个不被追踪肯定是好的，但是是什么原理导致不被追踪的呢，不是**才代表任意目录下吗？
https://git-scm.com/docs/gitignore
The slash "/" is used as the directory separator. Separators may occur at the beginning, middle or end of the .gitignore search pattern.
If there is a separator at the beginning or middle (or both) of the pattern, then the pattern is relative to the directory level of the particular .gitignore file itself. Otherwise the pattern may also match at any level below the .gitignore level.
