title: Adding file to git Ignore in flutter
body: <p>I'm working on making the flutter app and I'm trying to add my "key.properties" file, which includes passwords, into git ignore file. In my android/.gitignore file, I wrote </p>
  
  <pre><code>gradle-wrapper.jar
  /.gradle
  /captures/
  /gradlew
  /gradlew.bat
  /local.properties
  GeneratedPluginRegistrant.java
  /key.properties
  </code></pre>
  
  <p>like this and I thought it makes key.properties file ignored on my git hub, but when I push the code, I still can see it on GitHub. Is the way I write correct?? </p>
