title: How to select Development team for iOS app created in Flutter
body: <p>I am trying to deploy an iOS app to Device using Google's Flutter, but I get this error on the command line:</p>
  
  <pre><code>Building an iOS app requires a selected Development Team with a Provisioning Profile
  Please ensure that a Development Team is selected by:
    1- Opening the Flutter project's Xcode target with
         open ios/Runner.xcworkspace
    2- Select the 'Runner' project in the navigator then the 'Runner' target
       in the project settings
    3- In the 'General' tab, make sure a 'Development Team' is selected
  For more information, please visit:
    https://flutter.io/setup/#deploy-to-ios-devices
  Or run on an iOS simulator
  </code></pre>
  
  <p>Where and how do I do this? There is no "ios/Runner.xcworkspace" in the project. I know the installed Certificates and Provisioning profile work on my Mac, because I created and installed an app on my iOS device using Appcelerator, and it found everything I needed, and ran perfectly on device.</p>
