const ZoomFlatList = createZoomListComponent(FlatList);

const ListExample = () => {
  const renderItem = React.useCallback(
    ({ item }) => {
      return (
        <Zoom>
          <Image
            source={{

• software-mansion/react-native-gesture-handler#1804 (comment) Currently pan and pinch gesture are not triggering simultaneously in expo managed workflow. I'll look into it when I have some time. This issue doesn't happen on bare react native, release or expo dev client builds.
