crash with image that is larger than _maximumSizeBytes from image_cache.dart #19345
Description
Steps to Reproduce
- clone https://github.com/SteveAlexander/flutter_issue
- run in an iPhone simulator
- see that there's a busy loop continually reloading the PNG asset until it crashes
I think what's going on is, in painting/image_cache.dart, a decoded image that is larger than _maximumSizeBytes gets evicted from the cache as soon as it is put in there, and this somehow causes the asset to be continually reloaded from the device.
