maxCacheDimension property
The maximum size at which a DeviceImage should be cached in the global Flutter imageCache.
For example, to have all images with either a height or width of <= 800 pixels be cached but avoid adding anything larger than that set maxCacheDimension to 800. To cache any image use the constant value cacheAtAnySize. The constant cacheSuggestedCutoff is a reasonable tradeoff but particular applications will have different expected sizes so tuning may be required. Looking at the size of thumbnails can be a good guide so that the thumbnails are cached while the fullsize images are not.
The Flutter cache uses a lot of memory for large images since it caches them as bitmaps. For applications that are displaying a number of large images this may not be desirable, especially if those images are only displayed once. This property provides control over what images are put in cache. To avoid caching entirely set this value very high. Be aware that when displaying images in grids or lists the Flutter cache makes redraw during scrolling very smooth, without caching there will be redraw flicker.
Implementation
int maxCacheDimension = cacheAtAnySize;
