• What's your use case?
  I need to dynamically add text that needs to be completely(whole length) visible which changes the height of a node. But the changeNodeAtPath is not triggering my custom rowHeight function when I do that.

How could I explicitly call rowHeight recalculation or if I need to do something else?

interesting. The rowHeight callback should be called every time prop changes. might be because rowHeight is passed to react-virtualized.

I've got the same issue. I've added a button to expand a node. This button sets a field expanded in the node data and the rowHeight looks like that:

rowHeight={({node }) => 62 + (node.expanded ? 40 : 0)}

However when clicking the button the rowHeight function is not triggered. If set expanded: true to new nodes added to the tree, they appear with the expanded height. So it seems rowHeight is only called at creation

I've also noticed that adding a new node in the tree will force rowHeight to be evaluated and the previously expanded node will resize to the correct height.
