Invariant Violation: requireNativeComponent: "ARTShape" was not found in the UIManager.

Running both on react-native-cli and Expo (I know you mentioned expo deprecation), I receive the following error:

Invariant Violation: requireNativeComponent: "ARTShape" was not found in the UIManager.

This error is located at:

Using the example that you have provided I was unable to run any shadow effect on my app. React native v: >0.60
Adding pod manually doesn't work either. What should we do?

Did you tried uninstalling and reinstalling your app?

[huperniketes]

This occurs because @react-native-community/art is an upgrade of an old RN package that's manually linked. Remove the manual link with

npx react-native unlink @react-native-community/art

and the autolinking process in RN 60+ will work correctly the next time you run

cd ios && pod install && cd ...
