# 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.
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
```
