Uncaught TypeError: Cannot read properties of undefined (reading 'previousStyle') when experimenting readme example

See original GitHub issue

Issue Description

This package has external dependencies of react-native-reanimated and react-native-gesture-handler which must be installed separately. Before opening an issue related to animations or gestures please verify that you have completed ALL installation steps, including the changes to MainActivity.

Describe the bug When experimenting with the readme example and after swiping any list item, I got the error “Uncaught TypeError: Cannot read properties of undefined (reading ‘previousStyle’)”. After that, the browser almost froze during this weird error.

Just try the readme example.

Not applied?

Platform (iOS/Android): React Native or Expo version: Expo v43.0.3 react-native-reanimated version: 2.2.4 react-native-gesture-handler version: 1.10.3

Hey @tiagocpeixoto, have you tried downgrading react-native-reanimated to version 2.2.3? I had the same error in a different project, and downgrading the reanimated version solved the problem.
