 ## Limitations
 This is a new library so usability, documentation and performance are still work in progress.

-The following features are not yet implemented:
- Dash path effects
- Transforms on gradients (stroke and fills)
- Expose `Value callback` to modify dynamically some properties of the animation
- Text in animations has very basic support (unoptimized and buggy) 
+Only the [supported features of Lottie Android](https://airbnb.io/lottie/#/supported-features)
+are supported in this port.

 ## Flutter Web
 Run the app with `flutter run -d Chrome --dart-define=FLUTTER_WEB_USE_SKIA=true --release`
