Screen reader not working on Flutter 3.35.x #176360
Description
Steps to reproduce
- Create a basic skeleton app with text buttons
- Turn on the screen reader
- Focus a button, and hear no output
Expected results
The screen reader should read focused elements on screen, like "button".
Actual results
The screen reader does not read any elements on screen.
The screen reader seems to work fine on any version before 3.35.0, like 3.32.7.
