Layout jump on resizeOverlay, size not correct

[wood911]

Question 1: Overlay cannot fill the full screen, you need to adjust the height + 20 & set the position

// FlutterOverlayWindow.resizeOverlay(WindowSize.fullCover, WindowSize.matchParent, false);
FlutterOverlayWindow.resizeOverlay(WindowSize.fullCover, App.height.toInt() + 20, false);
FlutterOverlayWindow.moveOverlay(OverlayPosition(0, 5));

Question 2: Layout jump on resizeOverlay When resizing, the layout animation is ugly, flashing, and jumping

Detailed demo reference： https://github.com/wood911/myapp-float-flutter

This is a floating window application. When initialized, it is the sidebar size=(50,508) Click the volume 🔊 size=(fullCover,508) resizeOverlay error The display animation will jump and flash, and the sidebar will also move from the center to the right, but I checked that the position is correct (0,0) Why is it not centerRight, it should slide from the center to centerRight Click the brush 🖌 size=(fullScreen) The display animation will jump and flash when resizeOverlay

await FlutterOverlayWindow.showOverlay(
        alignment: OverlayAlignment.centerRight,
        enableDrag: false,
        overlayTitle: "悬浮窗口",
        overlayContent: 'Overlay Enabled',
        flag: OverlayFlag.focusPointer,
        visibility: NotificationVisibility.visibilityPublic,
        positionGravity: PositionGravity.auto,
        width: width ?? (50 * Get.pixelRatio).toInt(),
        height: height ?? (50 * Values.menuCount * Get.pixelRatio).toInt(),
        startPosition: OverlayPosition(0, 0),
);
