The animation on Android takes significant resources and slows down the UI. about lottie-flutter

Hi, thanks for the report.
I can reproduce the problem too.
I investigated a bit but I haven't found anything yet.

I'll try to look again soon.

Thank you for looking into it! It is, unfortunately, a critical issue for us.
Cheers

I'm sorry to hear that this is critical.
The library is still new, it is expected that there are still issue like this.

The good news is that it "shouldn't" be too hard to track it down and fix it. Maybe you can clone this library locally and experiment a bit your self? That would help a lot :-)

Is there chance that this is occurring when the size of the animation is bigger than the average? I have two different lottie animations on my app. One's size is 48 KB while the problematic one is 526 KB. If I use the one with bigger size, frame rate of my app decreases to 7 - 8 per second.

Good morning all,
I tried to install this app on my Samsung A5 and when I start the 360° animations all the app slow down and also the other lottie animations. On a Samsung Galaxy S10 the problem does not exist.
