How to get currently visible index in RN flat list

Question

I have a horizontal flat list where each item is width:300 All I am trying to do is to get index of currently visible item.

Answer 1

this.handleScroll = (event) => {
  let yOffset = event.nativeEvent.contentOffset.y
  let contentHeight = event.nativeEvent.contentSize.height
  let value = yOffset / contentHeight
}

Get the round-off value to calculate the page-number/index.
