RN 0.61 Release Build - 'Unhandled JS Exception: Invariant Violation: Unsupported top level event type "onGestureHandlerStateChange" dispatched

Hello I’m encoutering app crashes during release mode on both, iOS and Android after RN 0.60 to 0.61 upgrade.

I’m enclosing error from xCode console:

Does anyone encounter same issue? I will do my best to add reproducible demo ASAP.

Thank you so much for any help!

I’ve opened a new issue before research and I’m so sorry for that…

I added

import 'react-native-gesture-handler'

at top of index.js file as suggested in #320 and it works now 😸

I love those kind of magic fix, it ensures me that no one will ever take my place in the company, thank you again for that. Please do not ever document this.
