Performance issue after Flutter 3.27

[hasimyerlikaya]

After the Flutter 3.27 update, I noticed that my phone gets very hot during debugging.
I found out the problem is caused by an animation.

I use the flutter_animate package for animations, and I have a button with a shimmer effect.
When I activate the animation, CPU usage is increasing. When I disable it, everything seems fine.

To produce the issue, you can use this repo: flutter_debugging
The device is an iPhone Xs Max with iOS 18.1.1.

Have you ever noticed something like this?

I've seen some reports of isolated performance issues in 3.27 unrelated to Animate, so this may just be an issue with that. Are you seeing any evidence of slow downs on a production build, or just when debugging?

@gskinner Hi, I think it is just during the debugging. Flutter got a fix after I created this issue. I didn't test with the fix.
