iOS crash with newer devices when loading large images

🐛 Bug Report

My app crashed for some of my ios users (5-10%, mostly iPhone 13-15) when displaying a screen with CachedNetworkImage and the image was too big (like 2000x3000px). This was the crashlytics stacktrace:

The solution to this problem is to add reasonable values to maxHeightDiskCache or maxWidthDiskCache, but it took me some time to find that out.

Expected behavior

App should not crash, even when not specifying maxHeightDiskCache and maxWidthDiskCache

Reproduction steps

Display an large image using CachedNetworkImage

Configuration

Version: 3.3.1

Platform:

• :iphone: iOS (mostly iPhone 13-15)

Hello @TimBaumgart can you let me know what value have you added in the maxHeightDiskCache and maxWidthDiskCache, I am facing similar issue.

Thank you

Hi @vraj129 maxHeightDiskCache and maxWidthDiskCache seems to not have any effect on the issue. The actual "solution" for me was to disable impeller for iOS. See this issue for reference: https://github.com/flutter/flutter/issues/150183
