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.

Issue is reproducible using the code sample and steps outlined above.
I tested on a Pixel 7 running android 13 and a Nokia 6 running android 9.
On the Pixel 7, the bug reproduced as expected on both stable and master.
However, on the Nokia 6, everything worked just fine.
flutter doctor -v
sanderpensa commentedon Jul 25, 2023
I can confirm that on android 9 (Sony xz1 compact) it works as expected.
On Pixel 3XL (android 12), Pixel 5 (android 13) and Poco f4 (android 13) the issue is present.

note from android triage: @reidbaker to investigate further (determine if this is a regression or not).

Could someone please take a look at this? If the fix is really as simple as the above comments suggests, the fix itself is a 2-minute job; it's a shame for such a bug to cause issues for so many people for a year if not longer.
This flutter bug prevents me from using an app written in Flutter (though I would expect the same is true for MANY flutter apps, only I haven't used them yet).

I have submitted a PR, mostly based on horsemankukka's comment above.
flutter-team-archive/engine#53428
It's my first Flutter PR, so I'm not sure how to request a review, but hopefully someone here can pass it on the right person(s).

justinmc commentedon Nov 18, 2025
I think this issue can be closed now that flutter-team-archive/engine#53428 has merged to pass this through to MediaQuery, and #176492 has made Image respect that setting. If there's still work to do here let me know and I'll reopen!
