Lottie animations can cause Skia crashes on older iOS devices in 3.10 stable #130478
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
In our production app via Sentry we've found at least two different crashes on older devices caused by Lottie animations that began in Flutter 3.10 stable:
1. MTLTextureDescriptor has sampleCount set but is using a type that does not allow sampleCount
Device may crash when viewing the attached Lottie animation.
2. EXC_BAD_ACCESS
Crash reports for both included below. We're also using the attached SkSL shader cache. This problem started in Flutter 3.10.
Affected devices:
- iPhone X
- iPhone XR
- iPhone 8 Plus
- iPhone SE (2nd Gen)
Expected results
Does not crash.
Actual results
Crashes randomly.
Code sample
This can cause the MTLTextureDescriptor crash:
Lottie.asset(
'success.json',
frameRate: FrameRate.max,
repeat: false,
fit: BoxFit.contain,
