Function with_data_notes 

pub fn with_data_notes(
    child: impl IntoUiNode,
    on_changed: impl FnMut(&DataNotes) + Send + 'static,
) -> UiNode

Creates a note that samples DataNotes in a context.

The on_changed closure is called every time a note is inserted or removed in context. The closure can be called in any UiNodeOp, it is always called after the child processed the operation. The notes always change to empty on deinit.
