kToolbarHeight=56 status top=32.72727272727272 custom tabs height=32 加起来就是120.72727272727272

使用NestedScrollView，收缩完毕后使用LayoutBuilder获取的flexibleSpace的biggest.height是120.72727272727272

使用ExtendedNestedScrollView，收缩完毕后使用LayoutBuilder获取的flexibleSpace的biggest.height是120.72727272727283

这个误差好像会引起windows桌面端SliverAppBar的elevation失效(好像触发不了).

final double pinnedHeaderHeight =
        //statusBar height
        statusBarHeight +
            //pinned SliverAppBar height in header
            kToolbarHeight -
            0.1;

减去0.1之后. elevation效果就出来了. 测试了安卓模拟器的减不减0.1, elevation都正常.
