# element_embedding_demo
This package contains the application used to demonstrate the
upcoming Flutter web feature: "Element Embedding".
This was first shown on the Flutter Forward event in Nairobi (Kenya), by Tim
Sneath. [See the replay here](https://www.youtube.com/watch?v=zKQYGKAe5W8&t=5799s).
## Running the demo
The demo is a Flutter web app, so it can be run as:
```terminal
$ flutter run -d chrome
```
## Points of Interest
* Check the new JS Interop:
* Look at `lib/main.dart`, find the `@js.JSExport()` annotation.
* Find the JS code that interacts with Dart in `web/js/demo-js-interop.js`.
* See how the Flutter web application is embedded into the page now:
* Find `hostElement` in `web/index.html`.
