import React from 'react';
import {ScrollView, Text} from 'react-native';
const isCloseToBottom = ({layoutMeasurement, contentOffset, contentSize}) => {
const paddingToBottom = 20;
return layoutMeasurement.height + contentOffset.y >=
contentSize.height - paddingToBottom;
};
const MyCoolScrollViewComponent = ({enableSomeButton}) => (
<ScrollView
onScroll={({nativeEvent}) => {
if (isCloseToBottom(nativeEvent)) {
enableSomeButton();
}
}}
scrollEventThrottle={400}
