How can I show the tree expanded by default?

[kmusham]

I did not see a property to expand the tree by default.
Any suggestions on how to do that with your APIs?
Thanks

You can use startExpanded bool
and you can handle it any button or something like that,

TreeView(
startExpanded: startExpanded,
children: _getChildList(documentList),
)
