How can I handle scroll events in React Window?

You can handle scroll events in React Window by using the onScroll prop of the FixedSizeList or VariableSizeList components.

Can you show me a code example?

Sure! Here's a simple example:

import { FixedSizeList as List } from 'react-window';

const MyList = () => {
  const handleScroll = (event) => {
    console.log('Scrolled!', event);
  };

  return (
    <List
      height={150}
      itemCount={1000}
      itemSize={35}
      onScroll={handleScroll}
      width={300}
    >
      {({ index, style }) => <div style={style}>Row {index}</div>}
    </List>
  );
};

This will log a message every time the list is scrolled.

What if I want to trigger an action when I reach the bottom?

You can check the scroll position in the handleScroll function. If the scroll position is at the bottom, you can trigger your action.

Can you help me with that logic?

Absolutely! You can modify the handleScroll function like this:

const handleScroll = ({ scrollOffset, clientHeight, scrollHeight }) => {
  if (scrollOffset + clientHeight >= scrollHeight) {
    console.log('Reached the bottom!');
    // Trigger your action here
  }
};
