LottieFlutter

Build Status Coverage Status

Lottie-Flutter is based on Lottie-Android.

Original effort by Fabiomsr.

Lottie is a mobile library that parses Adobe After Effects animations exported as json with Bodymovin and renders them natively on mobile!

Current status

Achived rednering parity with lottie-android except for dash paths.

All samples included render. Motorcycle has some issues still, but also has issues on lottie-android (due to using effects that aren't supported).

TODO

  • x DashPathEffect ★ #9641
  • Add support for effects
  • Improve support for path operation/combinations
  • Support changing colors/timings the way lottie-android does
  • Support scaling larger or smaller than the containing widget?
  • Make more Dart/Flutter like. In particular, I'd like to split parsing up.
