why can't I see updates to the value of useTextEditingController?

Question

I would expect the effect to log the current value of the text whenever it changes, but it only runs for the initial value. Why?

class RecordForm extends HookWidget {
  final Record? record;
  const RecordForm({
    Key? key,
    this.record,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {

    final initialTitle = record != null ? record!.title : "";
    final _title = useTextEditingController
      .fromValue(TextEditingValue(text: initialTitle));

    useEffect((){
      log.wtf(_title.value.text);
    }, [_title.value]);

    return // ...
       TextFormField(
         controller: _title,
         // ...
       ),
     // ...
     ;
  }
}

Doing it that way initializes the TextEditingController once. I think if you want to listen to real-time changes you have to add a listener to it.

TextEditingController controller = useTextEditingController();
        
        controller.addListener(() { 
          print(controller.text);
        });
