Flutter - 以纵向和横向显示图像的空白

Question

如果我在图像中做横向或纵向，我会一直看到很多空白。我确实需要可滑动，所以不想过多地调整代码，但我确实希望它看起来可表示
我的代码有问题吗？
我确实添加了一张在横向和纵向模式下都发生的图片

  @override
      Widget build(BuildContext context) {

                ),
                leading: new IconButton(
                    icon: new Icon(styling.appBarBackArrowIcon),
                    onPressed: () {

SafeArea阻止您的图像进入屏幕的某些受限区域，例如缺口区域下方。或者对于某些设备，有 NavigationKeys在屏幕底部。尝试删除这些
干杯:)

child: SafeArea(
            top: true,
            bottom: true,
            right: true,
            left: true,
