我使用indexedStack来显示我的网页，他们都有一个抽屉，一切都好，直到现在，但当我打开抽屉的网页，它不涵盖垂直页面，我会附上图像。我会很高兴，如果你帮我。

body: IndexedStack(
        index: selectedTabIndex,
        children: const [
          HomePage(),
          ExplorePage(),
        ],
      ),

as you see the drawer it doesn't cover the page vertically
我尝试了太多的东西，如堆栈和.但我找不到解决方案。在一些地方，我看到了一些答案，包括一些键，但我没有得到它。
