  <p>I started IntelliJ IDE, and clicked on create new project</p>
  
  <p>I selected the Android Emulator: Nexus 5S, and the emulator opened up properly.</p>
  
  <p>I clicked on the green arrow to run, but I got the following error message:</p>
  
  <pre><code>════════════════════════════════════════════════════════════════════════════════
  No valid code signing certificates were found
  You can connect to your Apple Developer account by signing in with your Apple ID
  in Xcode and create an iOS Development Certificate as well as a Provisioning 
  Profile for your project by:
    1- Open 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. 
       You may need to:
           - Log in with your Apple ID in Xcode first
           - Ensure you have a valid unique Bundle ID
           - Register your device with your Apple Developer Account
           - Let Xcode automatically provision a profile for your app
    4- Build or run your project again
    5- Trust your newly created Development Certificate on your iOS device
       via Settings &gt; General &gt; Device Management &gt; [your new certificate] &gt; Trust

  Or run on an iOS simulator without code signing
