You should register
CacheObjectAdapter during hive initalization and pass a box to the
HiveCacheManager - this box will be where cache information will be stored.
/// register with the number of your choice (or default) Hive.registerAdapter(CacheObjectAdapter(typeId: 42)) /// provide the caching box final box = Hive.openBox('image_cache_info.hive'); /// finally whenever you are using cached network image library: CachedNetworkImage( imageUrl: "http://via.placeholder.com/350x150", placeholder: (context, url) => CircularProgressIndicator(), errorWidget: (context, url, error) => Icon(Icons.error), cacheManager: HiveCacheManager(box: box) // this is a singleton factory )
What this cache manager does is improving access time for cache information. It doesn't change how image binary data is loaded or saved.
