当手机碎屑大小变化时出现对准问题

Question

我有应用广告的主屏幕，我希望它固定在固定的位置，即使碎石尺寸发生变化，也应该将其固定在那个位置上，我很累，5.5碎石尺寸，就是这样，如果碎石尺寸为6或更大，图像，文本等所有东西的对齐方式都会改变位置，请在此帮助我

这是我正在尝试做的

这是我在屏幕尺寸为6 +时得到的结果

此目标代码

Answer 1

这很麻烦，因为您正在使用padding，height和width的值。根据设备的高度和宽度使用。

示例：

height: MediaQuery.of(context).height;
width: MediaQuery.of(context).width;

UPDTAE：

Widget build(BuildContext context) {
    // TODO: implement build
    Size size = MediaQuery.of(context).size;
    return SafeArea(
      child: Scaffold(
        extendBodyBehindAppBar: true,
        appBar: AppBar(
          leading: IconButton(
              icon: Icon(Icons.menu, color: Colors.deepOrangeAccent),
              iconSize: 34.0,
              onPressed: () {

              }),
          backgroundColor: Colors.transparent,
          elevation: 0,
        ),
        body: Stack(
          children: <Widget>[
            Center(
              child: new Image.asset(
                'assets/images/home_screen_back.png',
                width: size.width,
                height: size.height,
                fit: BoxFit.fill,
