this is bug. For now, my fix
Open the function definition of showCupertinoSheet in Flutter's source code.
2️⃣ Copy the implementation and create a custom version (e.g., myShowCupertinoSheet).
3️⃣ Locate line 232 (or search for this entry):
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);
4️⃣Remove
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);
5️⃣ Use myShowCupertinoSheet instead of the original function—problem solved!

Your "fix" works only with the last iOS that is able to set the right status bar color based on what's back.
There are 2 better workarounds that don't require to rewrite anything.
AppBarin the previous page, theAppBarset the rightSystemUiOverlayStylebased on the theme.or
AppBaruse to set theSystemUiOverlayStyle, that isAnnotatedRegiondarshankawar commentedon Mar 6, 2025
Thanks for the report. I was able to replicate the reported behavior on latest sdk versions.

Worth calling out: #164680 will not ensure that the system UI goes back to what it was when a Cupertino sheet is closed, it only removes overwriting the previous pages behavior. CupertinoSheetRoute does not reset the system UI because it can not know what to set the system UI to for the page behind it, it does not have that information. It is up to the previous page to set their system UI style. Which is how every route works in Flutter.
As previously mentioned, a routes system UI is usually automatically set by a navbar, or any widget that adds
AnnotatedRegion<SystemUiOverlayStyle>to the view. If that isn't present, you can add aAnnotatedRegion<SystemUiOverlayStyle>yourself. Or callSystemChrome.setSystemUIOverlayStylewhen returning to the page. BothNavigator.of(context).pushandshowCupertinoSheetreturn a future, soSystemChrome.setSystemUIOverlayStylecan be called when that future resolves.github-actions commentedon Apr 22, 2025
