Disclosure arrow does not disappear when folder becomes empty in UncontrolledTreeEnvironment

[zerolhs-tech]

I’m using UncontrolledTreeEnvironment with a custom dataProvider.
When I move items around (via drag and drop), sometimes a folder that used to have children becomes empty.

When I log getTreeItem, I can clearly see that isFolder: false and children: [] are returned.
However, in the UI the disclosure arrow (▼) is still shown for that item, even though it has no children anymore.

I would appreciate any guidance on how to resolve this issue.

Hi! Would need to see the code for this, the default renderers only render the chevron icon if the item is marked as a folder, but maybe you are also using a custom renderItemArrow handler that behaves differently: https://github.com/lukasbach/react-complex-tree/blob/main/packages/core/src/renderers/createDefaultRenderers.tsx#L40

There was no modification to the arrow, just making a css and only a little bit of override to the level of changing the shape.
The same thing can be seen in the single tree on the strybook connected to the homepage,
If you move Fruit > Berries > Black > 'Blackberry' to drag & drop . Black shows that arrow remains.
Thanks for your reply!!
