Error : 'ScrollView' has no propType for native prop 'RCTScrollView.onScrollAnimationEnd' of native type ' BOOL'

I’m stuck on this error.

I also tried replacing react-native package with “react-native”: “^0.47.2”, But didnt work.

Found the possible solution!

1. Bump expo version in package.json to 21.0.2
2. Bump react-native version in package.json to 0.48.4
3. Remove node_modules
4. npm install or yarn install
5. Change sdk version in app.json to 21.0.0 … ScrollView is working AGAIN! 😃

me too. It is an error in FlatList.

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in.

Check your code at App.js:8.

const styles = StyleSheet.create({
