Hello, we are facing several issues in our Crashlytics, it looks like an issue when there is not enough memory on the device, we support only devices with iOS 14+, full log:

Hey, this seems like old version of the package. Have you tried updating to v3? In v3 you can disable in memory cache and rely on system cache. This potentially will decrease memory consumption.

However, if you're running out of memory, I think this is more on the app side to profile with Instruments and see what resources can be released.

Thank you, I'll update the package and try the system cache, memory problems appear only when images are in the process of loading

dmytro-anokhin commented 3 years ago

One more thing to mention about v3 is that images are decoded lazily. This should give more time for the system to free resources. You can also specify lower maxPixelSize value to reduce memory footprint of the final image.

After update memory problem solved, thank you
