android该方案的实现思路有对应的flutter解决方案吗

请求该方案类似百分比适配方案，在flutter的pub.dev有类似方案的三方插件吗？查看了flutter的适配方案比如[sizer](https://pub.dev/packages/sizer),但是这种屏幕适配方案还得手动计算每个控件的设计稿实际占用比例，感觉很不方便。想实现一套类似于楼主的这种解决方案，但是代码中直接写UI设计稿对应的dp尺寸，内部去计算具体的转化比例。

Start by reviewing the issue description and the linked Flutter sizer package on pub.dev. Determine whether a Flutter solution matching AndroidAutoSize's design-dimension approach is requested, and define the package behavior and acceptance criteria before implementation; no project files or tests are named.
