How to distinguish mouse scrolling and scrollTo api scrolling ?

[NexxLuo]

I have two vitual list ,they need to scroll synchronously . I use then scrollTo change the list scroll position , but they will scroll in a loop ? In the another library react-window , onScroll event has an parameter called scrollUpdateWasRequested.
How can i do with react-virtuoso ?

This is not supported currently, it does sound like a nice to have enhancement. As an alternative, You can maintain scrollUpdateFlagWasRequested as an external flag in your own state. Feel free to post an example, it can be useful for others as well.

I added an id to the Virtuoso component. In useEffect, a wheel event is added to the Virtuoso component each time a user scrolls the mouse so that it can be detected.

  useEffect(() => {
    const vrtElement = document.getElementById("vrt");
    vrtElement?.addEventListener("wheel", doSemething);

    return () => {
      vrtElement?.removeEventListener("wheel", doSemething);
    };
  }, []);

<Virtuoso
      ref={virtuRef}
      style={{
        height: "100vh",
      }}
      id="vrt"
      data={getDataEntries()}
      itemContent={(index, data) => {return ()}
       />
