 # Example of switching between full-screen Flutter and Platform View
 
-This project demonstrates how to bring up a full-screen iOS/Android view from a full-screen Flutter view along with passing data back and forth between the two.
+This project demonstrates how to bring up a full-screen iOS/Android view from a
+full-screen Flutter view along with passing data back and forth between the two.
+
+On iOS we use a CocoaPods dependency to add a Material Design button, and so
+`pod install` needs to be invoked in the `ios/` folder before `flutter run`:
+
+```
+pushd ios/ ; pod install ; popd
+flutter run
+```
