Flutter UI - Container Border Margin 界面问题

Question

我一直在尝试在我的电子商务主页上工作，正如您从屏幕截图中看到的那样，我正在尝试修复我的主屏幕中的类别图标位置尽管它在 Android 切换到 iOS 屏幕时似乎很稳定，但它变得不稳定，无法点击。

知道我做错了什么吗？

目标与现实

主屏幕

class _HomeScreenState extends State<HomeScreen> {

  var height = Get.height;
  var width = Get.width;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Padding(
        padding: const EdgeInsets.all(4.0),
        child: Column(
          children: [
            Padding(
              padding:
              EdgeInsets.only(top: 40, left: 0, right: 0, bottom: 0),
              child: Column(
                children: [
                  Container(
                    height: 120,
                    width: 365,
                    decoration: BoxDecoration(

            )
          ],
        ),
      ),

Answer 1

您可以试试 Flexible - 它控制行、列和 Flex 等基本 flex 小部件的子项如何填充它可用的 space

即

Flexible(
  fit: FlexFit.tight,
  child: Foo(),
);

Answer 2

已解决，我在调用 CategoriesGrid 之前添加了 Padding 并删除了 Container

这是更新后的代码

主屏幕

                 Container(
                      height: height/8,
                      width: 365,
                      decoration: BoxDecoration(
                                blurRadius: 2.0,
                                offset: Offset(2.0, 2.0))
                          ]),
                      child: Padding(
                        padding:  EdgeInsets.only(top:Get.height/34),
                        child: CategoriesGrid(
                          height: height,
                          width: width,
                          internetAvailable:
                          homePageController.internetAvailable,
                          listOfTitles: homePageController.listOfTitles,
                          listOfCategoryImages:
                          homePageController.listOfCategoryImages,
                        ),
                      ),
