# flutter_module
An example Flutter module used in the Flutter add-to-app samples. For more
information on how to use it, see the [README.md](../README.md) parent
directory.
## Getting Started
For more information about Flutter, check out
[flutter.dev](https://flutter.dev).
For instructions on how to integrate Flutter modules into your existing
applications, see Flutter's
[add-to-app documentation](https://flutter.dev/docs/development/add-to-app).
