ExpansionTile accessibility information doesn't read Expanded/Collapsed (iOS) #132264
Description
Internal: b/269139224
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
- Click on the ExpansionTile component with text "xxx" with accessibility mode enabled. Then, it will read like "xxx, Expanded double tap to collapse" or "xxx, Collapsed double tap to expand".
- Double click on the ExpansionTile component, then immediately it will only read "xxx", but the expected words are "xxx Expanded" or "xxx Collapsed"
- Note if you single click on the ExpansionTile component it will still read out the output described in step 1 as expected. The only issue is just at step 2, when user finishes the double clicking.
It seems that this issue has been fixed by #74963, but reverted by #121699 with a new solution introduced. In the final video shown by #121699, this issue exists. Furthermore, the error seems to be that "Expanded" and "Collapsed" hints are interrupted when being announced. Related issue --> #122101. One solution might be delaying the announcement.
Expected results
When double clicked, the ExpansionTile component should read out "xxx Expanded" or "xxx Collapsed".
Actual results
When double clicked, the ExpansionTile component only reads out "xxx".

Thanks for the report. I do see the same behavior as described, ie, when we double tap to expand, it doesn't read out at that time, but after if we single tap on the expanded list, it reads out as
expanded.The same behavior occurs using the example as well.
stable, master flutter doctor -v

@chunhtai Was the PR above expected to fix this? It sounds like it's still broken on master.

@math1man i can fix this. Do you any recommendations for how many long we should delay? Considering different languages.
math1man commentedon Feb 21, 2024
No idea. The
Formwidget uses a delay of 1 second for this exact purpose.TahaTesser commentedon Feb 21, 2024
I can take this issue and fix, if this sounds reasonable to you.
