What is the current behavior?
I am testing the new VirtualizedList in new release 0.6.0 and it works well in web and iOS. also inverted prop works which is great for messaging app ! Thanks for the update.

In web client, we do get a number of warnings due to unrecognized props and eventHandlers. nothing breaks so this is low priority:

Warning: React does not recognize the `extraData` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `extradata` instead. If you accidentally passed it from a parent component, remove it from the DOM element.
    in div (created by View)
    in View (created by ScrollViewBase)
    in ScrollViewBase (created by ScrollView)
    in ScrollView (created by VirtualizedList)
....

Same warnings for a number of other props for same element:

Warning: React does not recognize the `keyExtractor` prop on a DOM element.
Warning: React does not recognize the `renderItem` prop on a DOM element.
Warning: React does not recognize the `getItemCount` prop on a DOM element.
Warning: React does not recognize the `getItem` prop on a DOM element. 
Warning: React does not recognize the `disableVirtualization` prop on a DOM element. 
Warning: React does not recognize the `initialNumToRender` prop on a DOM element.
Warning: React does not recognize the `maxToRenderPerBatch` prop on a DOM element.
Warning: Unknown event handler property `onEndReachedThreshold`. It will be ignored.
Warning: React does not recognize the `updateCellsBatchingPeriod` prop on a DOM element.
Warning: React does not recognize the `windowSize` prop on a DOM element.
Warning: React does not recognize the `invertStickyHeaders` prop on a DOM element.

If the current behavior is a bug, please provide the steps to reproduce and
if a minimal demo of the problem via Glitch or similar (template:
https://glitch.com/edit/#!/react-native-web-playground).

What is the expected behavior?

No warnings ?

• Device: Macbook Pro

I also get some warnings
InteractionManager is not supported on web
when using the new VirtualizedList :

InteractionManager is not supported on web
runAfterInteractions @ index.js?f958:21
(anonymous) @ index.js?4614:75
setTimeout (async)
schedule @ index.js?4614:74

measure @ index.js?18e2:63
measure @ index.js?a21a:56
Component._handleLayout @ index.js?242d:132

This seems to come from
// ./node_modules/react-native-web/dist/exports/InteractionManager/index.js

Not sure if I am doing something wrong ? I used minimal options for VirtualizedList and the render component has some TouchableOpacity components with onPress event handlers, but I am not sure if that is what triggers these warnings?

It also seems that VirtualizedList causes my react-native-web project to fail to compile with babel-loader in webpack, resulting in the following error:

./node_modules/react-native-web/dist/vendor/VirtualizedList/index.js
Module build failed: TypeError: ./node_modules/react-native-web/dist/vendor/VirtualizedList/index.js: Property id of VariableDeclarator expected node to be of a type ["LVal"] but instead got "BinaryExpression"

I also faced issue in Chrome browser. But I updated
"react-scripts": "1.1.0" -> "react-scripts": "1.1.4"`

./node_modules/react-native-web/dist/vendor/VirtualizedList/index.js
249:44-55 "export 'default' (imported as 'Batchinator') was not found in '../Batchinator'

I'm still getting the issue where I can't compile a project using anything above [email protected] with babel-loader in webpack.

./node_modules/react-native-web/dist/vendor/VirtualizedList/index.js
Module build failed: TypeError: ./node_modules/react-native-web/dist/vendor/VirtualizedList/index.js: Property id of VariableDeclarator expected node to be of a type ["LVal"] but instead got "BinaryExpression"

You'll have to put together an example project to show me the issue
