Can't change only enableDrag flag while being shown overlay

[kimilini1227]

Hi.
I create overlay paiting app.
Therefore I need to switch enableDrag flag depend on whether start position of dragging is on canvas or top window bar.

However according to the documentation the way that change enableDrag flag while being shown overlay is only resizeOverlay that end up changing overlay size so I can't change only enableDrag flag.

In the first place why resizeOverlay have a role change enableDrag flag?
This role must be defined as a separate method.

My showOverlay

FlutterOverlayWindow.showOverlay(
  height: HEIGHTOVERLAY,
  width: WIDTHOVERLAY,
  alignment: OverlayAlignment.topLeft,
  flag: OverlayFlag.defaultFlag,
  enableDrag: true,
  positionGravity: PositionGravity.none,
  startPosition: OverlayPosition(XPOSOVERLAY, YPOSOVERLAY),
);

My GestureDetector in canvas

GestureDetector(
  onPanStart: (DragStartDetails start) async {
    await FlutterOverlayWindow.updateEnableDrag(false);
  },
  onPanEnd:  (DragEndDetails end) async {
    await FlutterOverlayWindow.updateEnableDrag(true);
  },
  child: ...
}

I think so，This role must be defined as a separate method.
