我的Flutter项目是：here。当我尝试运行Rahulraj分支中的代码时，我得到以下错误：

/C:/Users/Sanmitha/AppData/Local/Pub/Cache/hosted/pub.dev/flutter_screenutil-5.6.1/lib/src/screen_util.dart:64:16: Error: The getter 'viewConfiguration' isn't defined for the class 'FlutterView'.
 - 'FlutterView' is from 'dart:ui'.
Try correcting the name to the name of an existing getter, or defining a getter or field named 'viewConfiguration'.
    if (window.viewConfiguration.geometry.isEmpty) {
               ^^^^^^^^^^^^^^^^^

更新：flutter_screenutil更新了，请使用实际版本（5.7.0+）。
=原始答案=======================================================================================================================================================================================================================================================
问题出现在最后一次Flutter更新中：https://github.com/flutter/flutter/issues/121742.中的FlutterView. viewConfiguration属性被删除，但它在flutter_screenutil库中使用。
可能的解决方案：

回滚到Flutter的任何以前版本
从flutter_screenutil的分支链接这个库，在那里这个问题被修复了（只是暂时的解决方案!），在flutter_screenutil更新后立即返回依赖项）：

flutter_screenutil:
    git:
      url: https://github.com/dmakeev/flutter_screenutil
      ref: fix-463

一般建议使用稳定Flutter通道而不是主通道。

此错误发生在Flutter的最新版本（3.9.0-1.0）（2023年3月）中。可能的解决方案是，
1.使用Flutter Version Manager（fvm）https://pub.dev/packages/fvm降级项目中flutter的版本。flutter pub global activate fvm
或者.. 2.删除这个软件包flutter_screenutil并使用不同的选项如MediaQuery.
OR.. 3.降级Flutterflutter downgrade v1.17.0
