title: Developing Flutter iOS plugin packages - Pods folder in Xcode project is empty
body: <p>I am developing a plugin package for Flutter. I follow the instructions exactly as written in a tutorial here: <a href="https://flutter.io/developing-packages/#step-2c-add-ios-platform-code-hmswift" rel="nofollow noreferrer">Step-2c-add-ios-platform-code-hmswift</a>.
  It says to open <code>hello/example/ios/Runner.xcworkspace</code> with xcode, and then:</p>
  
  <blockquote>
    <p>iOS platform code of your plugin is located in Pods/DevelopmentPods/hello/Classes/ in the Project Navigator</p>
  </blockquote>
  
  <p>But, when I open xcode project as specified, there is nothing under <code>Pods</code> folder, it is empty:</p>

  <p>How can I fix this { I am still kinda Xcode noob } ...</p>
  
  <p>EDIT: iOS specific plugin files are there on the disk, so I guess this is just some project file "wiring" bug or something like this.</p>
