title: Stuck on step 2b in the Flutter Native Plugin guide
body: <p>So I'm trying to get started with Flutter Plugin development, and I'm stuck on step 2b <a href="https://flutter.dev/docs/development/packages-and-plugins/developing-packages#step-2b-add-android-platform-code-ktjava" rel="nofollow noreferrer">HERE</a>.</p>
  <p>Android Studio just shows the error:</p>
  <pre><code>Cannot Import Project
  The project file specified already exists.
  </code></pre>
  <p>I'm pretty sure I've followed the instructions:</p>
  <ol>
  <li><code>flutter create --org com.example --template=plugin hello</code></li>
  <li><code>cd hello/example; flutter build apk</code></li>
  </ol>
  <p>These steps all work fine, the example app seems to build, and then I get to step 2b, and Android Studio shows the error above.</p>
  <p>flutter doctor:</p>
