How to control the total size of cached images.

[lan2000]

🐛 Bug Report

List built with listview.build. The list is long and there are pictures in the list. This image has "memCacheHeight" set. Keep scrolling the list, and an error occurs after ten minutes. If I don't set memCacheHeight, after sliding the list for a period of time, the program directly freezes, prompting "the program is not responding". How to control the total size of cached images. I set PaintingBinding.instance.imageCache.maximumSizeBytes = 1024*1024*80; and it didn't work.

log:

CursorWindow: mmap() failed: errno=12.

 DatabaseException(Could not allocate CursorWindow '/data/user/0/package/files/libCachedImageData.db' of size 2097152 due to error -12.) sql 'SELECT * FROM cacheObject WHERE key = ?' args [https://.....jpg]
