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

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.

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.
