I'm working on an app (mainly for iOS) that contains ListView.builder with lots of pictures (about 64 pictures, 7.7 Mb size in total on disk) and I have a huge performance problem on devices with 1 Gb RAM and lower. I tried to decrease imageCache _maximumSizeBytes to 30 Mb and now the app works better in terms of smoothness but it's bad workaround because now pictures are uploaded from the cache and it leads to freezes in pictures appearing in the list.

I'm sure I'm facing the same problem as in #13242. Any suggestions/ideas?
