Steps to Reproduce

  Timer? _debounceTimer;

StreamSubscription editorStreamSubscription = textEditorController.changes.listen((DocChange event) {
   // Prevent re-sending remote changes
   if (event.source == ChangeSource.remote) {
      talker.warning("Skipping remote change to prevent infinite loop.");
      return;
   }

   todo.description = jsonEncode({
      'before': event.before.toJson(), // Convert `before` Delta to JSON
      'change': event.change.toJson(), // Convert `change` Delta to JSON
   });

   talker.warning("editor changes: ${todo.description}");

   _debounceTimer?.cancel();
   _debounceTimer = Timer(Duration(milliseconds: 1000), () async {
       await crdt.saveModel(todo);
      });
});

typing in the editor results in a wrong Delta from the third row. as it missed to make a Delta to insert: "for some reaso"

{"before":[{"insert":"this is a test if everything work\n"}],"change":[{"retain":33},{"insert":"s"}]},

{"before":[{"insert":"this is a test if everything works\n"}],"change":[{"retain":34},{"insert":"."}]},

{"before":[{"insert":"this is a test if everything works. for some reaso\n"}],"change":[{"retain":50},{"insert":"n"}]},

{"before":[{"insert":"this is a test if everything works. for some reason\n"}],"change":[{"retain":51},{"insert":"."}]}

i will try with a buffer but then all changes will be recorded again. i really want a diff (Delta) after a person stops typing after 1000 ms.

Expected results

correct delta's even when debounce...

Actual results

see above...

when i use rxdart with bufferTime and recompose all changes during the buffer it does work. but debouncing just won't work.

StreamSubscription editorStreamSubscription = textEditorController.changes
   .bufferTime(Duration(milliseconds: 1000))
   .listen((List<DocChange> events) async {});

perhaps this is a shortcoming of the package at this moment, as i would think in the compiled quill there should be something like a buffer or debounce method inside of it..?
