windowManager.close() not really close child window

[acquytrenthienduong]

I’ve noticed that windowManager.close() does not fully close the child window—it only hides it. Is there a way to completely close the child window?

通过加入一个参数来判定
onClose: () async {
// 窗口隐藏前，强制卸载 Widget 树，切断内部所有的通讯
setState(() {
_isWindowClosed = true;
});

        await windowManager.hide();

然后在app 中 的build中加入
@OverRide
Widget build(BuildContext context) {
if (_isWindowClosed) {
// 窗口关闭时返回空组件，彻底卸载整个挂载树
return const SizedBox.shrink();
}

这样就可以保持一帧，下次再打开该二级窗口时，可以做到快速打开
