FlatList TypeError: undefined is not an object (evaluating 'props.getItem')

🐛 Bug Report

Any <FlatList> in my app now throws this error in IOS and Android TypeError: undefined is not an object (evaluating ‘props.getItem’) it’s similar to : https://github.com/facebook/react-native/issues/21154

it’s not just yellowbox, it’s happening for any and all lists (FlatList, SectionList) in my app. i’m not sure if this is related, but everthing went south after installing and linking https://github.com/react-native-community/react-native-webview

To Reproduce

RNCA add a bunch of other modules (see info below) use a FlatList

Expected Behavior

A nice and robust FlatList component in my app

Code Example

even the ‘Minimal Example’ breaks: <FlatList data={[{key: 'a'}, {key: 'b'}]} renderItem={({item}) => <Text>{item.key}</Text>} />
