Description

exactly this issue: #31109. this is still a problem.


using FlatList with stickyHeaderIndices, viewabilityConfigCallbackPairs, and ListHeaderComponent, when scrolling the list onViewableItemsChanged is called. the viewableItems includes items that are behind (not viewable) the sticky list header.

const viewabilityConfig = {
  minimumViewTime: 1000,
  waitForInteraction: true,
  itemVisiblePercentThreshold: 100,
}

const onViewableItemsChanged = React.useCallback(
  ({ viewableItems, changed }) => {
    console.log('viewableItems', viewableItems)
    console.log('changed', changed)
  },
  []
)

const viewabilityConfigCallbackPairs = React.useRef([
  { viewabilityConfig, onViewableItemsChanged },
])

<FlatList
  stickyHeaderIndices={[0]}
  viewabilityConfigCallbackPairs={viewabilityConfigCallbackPairs.current}
  ListHeaderComponent={() => <MyListHeader/>}
/>
