AccessibilityFeatures.disableAnimations flag is not set on app startup and animations are not disabled in app running on Android 12+ device. #130976
Description
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
- On Android 12+ device disable animations from Settings > Accessibility > Remove animations.
- Run the app flutter run --release (does not matter if in release, profile or debug mode, we have this bug in live app also).
- Observe AccessibilityFeatures.disableAnimations flag is not set, animations are not removed.
- Put the app to backgound (do not close it), and change the "Remove animations" setting off and on again from Settings > Accessibility > Remove animations.
- Open app from recents, observe AccessibilityFeatures.disableAnimations flag is updated and set after few seconds and animations are disabled.
Expected results
App animations are disabled on Android 12+.
Actual results
Animations are not disabled.
