Repository navigation
[GoRouter] and CupertinoSheetRoute doesn't work correctly together. CupertinoSheetRoute always uses root navigator to pop. #172010
Description
Steps to reproduce
- Create an app with GoRouter using StatefulShellRoute;
- Push from one of StatefulShellBranche's to CupretinoSheetRoute;
- Try to close pushed route.
Expected results
Pushed route will be closed without problem.
Actual results
CupertinoSheetRoute uses root navigator and pops entire stack of pages.

For me it seems like problem is in this lines of 'flutter/lib/src/cupertino/sheet.dart' lines 795-799.

@Greatest4Ce Thanks for the report. Based on the error log, it seems similar to #142678 for which the reasoning of closure is: #142678 (comment), so please check if it helps further in your case or not.
Greatest4Ce commentedon Jul 14, 2025
@darshankawar Thanks for your answer. Yeah, issue #142678 seems familiar, I read it and tried given solutions, but found that it's not my situation. Author tries to close BottomSheetRoute by "his hands" and he navigates to it by showDialog() or showBottomSheet() methods.
Differences of my case:
And I found that ModalBottomSheetRoute's (I use it for Android UX, pls tell me if I wrong) logic works correctly:
code from flutter/lib/src/material/bottom_sheet.dart lines 722-726
... onClosing: () { if (widget.route.isCurrent) { Navigator.pop(context); } }, ...Greatest4Ce commentedon Jul 14, 2025
For me I found solution in creating GlobalKey for GoRouter and pass it like this:
In this case new route pushing to main router and everything works correctly. But in case then a want to push this route to nested ShellRoute's navigator CupertinoSheetRoute always pop's rootNavigator.

Thanks for the update. I was able to replicate the reported behavior. Keeping the issue open for team's tracking.
