flutter_cache_manager_hive

Just like flutter_cache_manager but uses hive instead of sqlite to store cache object information.

EXPERIMENTAL

Usage

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
)

Performance

What this cache manager does is improving access time for cache information. It doesn't change how image binary data is loaded or saved.
