...ANSWER
Answered 2020-May-01 at 20:32About the warning.
Yellow Warnings in react-native discloses inefficient code in your application which eventually leads to a performance issue or increase in memory consumption.
Yes, the warning nesting VirtualizedList inside a plain ScrollView is bad for your app.
This usually happens while rendering Flatlist inside a ScrollView. (from your import)
- Flatlist fails to calculate the size of the current window and will try to render everything at the same time which leads to a performance problem.
How to get rid of the warning
It's easy to resolve this issue just remove the ScrollView
and move the components around Flatlist
to ListHeaderComponent
and ListFooterComponent

However, you should be able to find the .xcodeproj here: https://github.com/react-native-community/react-native-push-notification-ios/tree/master/ios

Answered 2017-Nov-11 at 05:00Create an index.js file in root directory of your project and copy your index.android.js or index.ios.js into it.
after RN 49 by default, we don't have different entries for ios and android. so we have just one index.js file that both android and ios use it.
