# multiple_flutters_android
This is an add-to-app sample that uses the Flutter engine group API to host
multiple instances of Flutter in the app.
## Getting Started
```sh
cd ../multiple_flutters_module
flutter pub get
cd -
open -a "Android Studio" multiple_flutters_android/ # macOS command
# (build and run)
```
For more information see
[multiple_flutters_module](../multiple_flutters_module/README.md).
