Can TreeView support using up/down arrow to select tree node?

Hello! They are part of the Flutter focus system. They work on Windows, but I'm afraid they don't work on the web (platform behavior).

[benny856694]

No, doesn't work on Windows either. My project is for Windows, and it doesn't work

[bdlukaa]

That is odd. Can you show us a GIF of the behavior you get?

[benny856694]

Here it is: screen shot, when I press up/down, the focus moves to the right widget.

What happens when you press Tab or Shift-Tab? The same behavior?

[benny856694]

yes, same behavior

[benny856694]

I simplified the widget tree by removing the parent widget of the TreeView, now the up/down key works

You can attempt to give focus to the entire tree view using a FocusScope and autofocus: true

up/down arrow still not working by wrapping TreeView inside a FocusScope and setting autofocus to true
