Hello! We’re actively working on porting Reanimated to Fabric but it’s not completely ready yet. In fact, Reanimated integrates quite closely with the renderer system so we need to rewrite some parts specifically for Fabric and that’s exactly what we have been doing for the past few months.

The good news is that in parallel we’re porting react-native-gesture-handler and react-native-screens to Fabric as well so hopefully the developers will be able to enable Fabric in their apps as soon as possible.

edit: Reanimated, Gesture Handler and Screens finally support Fabric! 🎉

FYI this does still seem be happening with react-native 0.68.1 and react-native-reanimated 2.8.0. I really appreciate all the hard work you guys are doing!
