How to refresh UI state for node after check-box is clicked on such node?

[UlyssesAlves]

I need a tree with a checkbox on each of its nodes. My current problem is that the checkbox ui state does not change right after I click the checkbox for that node, but it is then updated correctly when I expand or shrink the tree.

How can I make this work so that when a checkbox os pressed it's UI wii change too on the node?

Wrap the node widget in a ValueListenableBuilder, and use the node.listenableData as the value to listen. Use node.data to assign or get the data.
The node extends the ValueListenable, so it can be used as a ChangeNotifier or ValueListenable.

Apologize for the late reply.

//sample code
 ValueListenableBuilder(
      valueListenable: node.listenableData,
      builder: (context, page, child) {
        return SomeWidgetHere();
      },
    );
