1. Great library, thanks.

2. Not sure if this is a bug or a feature request, but I noticed that the "Large Document (10,000+ Rows)" example program has huge performance issues when you start dragging the scrollbar (both in debug and release mode). Video below

At first I thought it was some implementation issue, but after a bit of research and experimentation I found that it seems to be a flutter [issue] (https://github.com/flutter/flutter/issues/75399). One of the comments suggested [JK_fast_listview](https://pub.dev/packages/jk_fast_listview) – I (partially) integrated it into appflowy-editor and the results seem promising, see the second video:

So my question is: is this a known problem? Are there any solutions? And if not, maybe this approach is worth considering?

Thank you! I'd like to hear your thoughts.
