how to count views in react native flatlist items - react-native

Question

I have a flat list and it contains a list of posts and videos, now I need to count the views for each item, I tried using viewabilityConfig and onViewableItemsChanged in the flat list and it works fine if I only want to count visible item as a view.
problem is that I had a function written inside onViewableItemsChanged for pausing video right after user scrolls from video.
now I have two functions with different execution times. how can I handle these two functions ?
onViewableItemsChanged = (info) => {
if (this.props.enableView) {
console.log('item viewed after minimumViewavlitytime 5s: ', info) //done after 5s of view time
}
this.pauseVideoFunction(); //done exactly after scrolling
};
viewabilityConfig = {
minimumViewTime:5000,
waitForInteraction: false,
viewAreaCoveragePercentThreshold: 95,
}

Answer 1

i handled it this way:
removed minimumViewTime from config file
added this to constructor since its a class component
this.debouncedViewCount = debounce(this.countView, 5000);*
called debouncedViewCount inside onViewableItemsChanged
now I have a denounced view counter which runs after 5 second if scroll doesn't move and can pause video right after scrolling
class ComponentA extends React.Component {
constructor(props) {
super(props);
this.debouncedViewCount = debounce(this.countView, 5000); //aaaaaaaaaaa
}
countView = (info) => {
debounce(console.log('Debouced 5s', info), 5000, false)
}
onVideoExitScreen = (info) => { //todo working on view aaaaaaaaaaaaaaaaaaaa
if (this.props.enableView) {
this.debouncedViewCount(info);
}
pauseVideoFunction();
};
}
//inside Flatlist
onViewableItemsChanged={this.onViewableItemsChanged}
