+# 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`.
