Repository navigation
Screen reader loses focus from previous route after navigation #118397
Description
After navigating the semantics nodes with a screen reader (right/left swipes), entering a new page (Navigator.push), and returning from it (Navigator.pop), the screen reader is focused on the beginning of a route instead of on the last focused node.
This is an issue that the accessibility consultant from my project pointed out and it's a big blocker for people with disabilities to effectively use the application that has forms with full-page pickers.
I tested it only on iPhone's VoiceOver.
Test environment
iPhone 13 Pro, iOS 16.0.2

I may try to fix that if that's considered a bug and not intended behavior, but I'd like some minimal guidance on where to cache the semantics focus position and where/how this focus is maintained
darshankawar commentedon Jan 13, 2023
Thanks for the report. I see the same behavior upon navigating back from
childtorootscreen, the focus goes to the app heading. Verified on iPhone 6s.Although it could be related to #97747
stable, master flutter doctor -v

Hello!
I wanted to work on this issue but was pleased to find that it is no longer reproducible from the 3.27.2 version of Flutter!
Most likely, the issue was resolved in the following pull request: #135771
Could you please check if the issue is still relevant?
fvm flutter doctor -v
