Hi @sreevishnuqa, thanks for the report. Routing to the iOS team.
hellohuanlin commentedon Aug 20, 2026
By looking at the numbers, it feels like the new iOS is dropping support for low resolution presets (width 288), causing it to fallback to a higher minimum resolution (width 480). PRs welcome.

Thanks!

@preethi0228-git Hello, the error message shows failure at line 46, which is a comment line. This means you were not running on latest master. Can you pull the master and try again?
sreevishnuqa commentedon Oct 23, 2026
@hellohuanlin Thanks for the update. Verified on the latest Flutter master (3.50.0-1.0.pre-209) and Xcode 27.2 RC. The issue is no longer reproducible, and all camera_avfoundation integration tests passed.
