在Flutter最新升级到3.10.0后，窗口API被贬低了，我试图使用View.of（context）.platformdispatcher来代替，我应该如何将window.viewPadding替换为View.of（context）.platformdispatcher.viewPadding，因为它会给我这个
The getter 'viewPadding' isn't defined for the type 'PlatformDispatcher'. Try importing the library that defines 'viewPadding', correcting the name to the name of an existing getter, or defining a getter or field named 'viewPadding'.dar
PlatformDispatcher也应该有ViewPadding getter

viewPadding定义在FlutterView中。要获取FlutterView，可以用途：

final views = PlatformDispatcher.instance.views;

views返回FlutterViews的Iterable。然后，您可以访问第一个视图以获取viewPadding：

final viewPadding = PlatformDispatcher.instance.views.first.viewPadding;
