MemoryStore<T> class

An in-memory implementation of Store that supports tagging.

MemoryStore keeps all cached data in a local Map, making it fast but volatile. Data is lost when the store instance is garbage collected or the application terminates.

This implementation also supports tag-based operations through TaggableStore, enabling grouped cache invalidation.

For shared storage across multiple Syncache instances, consider using SharedMemoryStore instead.

Example:

final cache = Syncache<User>(
  store: MemoryStore<User>(),
);
