How can a infinite scroll item have a dynamic height?

[zi-gae]

In the official documentation, the height setting is understood as follows:

constrowVirtualizer=useVirtualizer({count: hasNextPage ? allRows.length+1 : allRows.length,getScrollElement: ()=>parentRef.current,estimateSize: ()=>300,// item heightoverscan: 4,});

If the height of A changes according to the response of the server, is there a way to dynamically change the height?

my code:

functionVirtualizerScroll(){const{ data, hasNextPage, isFetchingNextPage, fetchNextPage }=useInfiniteQuery(...params);constparentRef=React.useRef<HTMLDivElement>(null);constallRows=data ? data.pages.flatMap((d)=>d.rows) : []constrowVirtualizer=useVirtualizer({count: hasNextPage ? allRows.length+1 : allRows.length,getScrollElement: ()=>parentRef.current,estimateSize: ()=>300,overscan: 4,});constitems=rowVirtualizer.getVirtualItems();React.useEffect(()=>{const[lastItem]=[...rowVirtualizer.getVirtualItems()].reverse();if(!lastItem){return;}if(lastItem.index>=allRows.length-1&&hasNextPage&&!isFetchingNextPage){fetchNextPage();}},[hasNextPage,fetchNextPage,allProducts.length,isFetchingNextPage,rowVirtualizer.getVirtualItems(),]);return(<divref={parentRef}style={{height: 1000,width: '100%',overflowY: 'auto',}}><divstyle={{height: rowVirtualizer.getTotalSize(),width: '100%',position: 'relative',}}>{items.map((virtualRow)=>{constresponse=allRows[virtualRow.index];return(<divkey={virtualRow.key}data-index={virtualRow.index}ref={rowVirtualizer.measureElement}style={{position: 'absolute',top: 0,left: 0,width: '100%',height: `${virtualRow.size}px`,transform: `translateY(${virtualRow.start}px)`,}}><DynamicCardresponse={response}/></div>);})}</div></div>);}

I figure out various ways but can't find a way. I was wondering if anyone could give me some guidance or an example.
