CacheStorage class abstract

Storage backend for the cache layer.

Default implementation is InMemoryCacheStorage (no dependencies).

Swap in your own for persistent storage:

class HiveCacheStorage implements CacheStorage {
  @override Future<String?> get(String key) async => Hive.box('cache').get(key);
  @override Future<void>    set(String key, String value, Duration ttl) async {
    await Hive.box('cache').put(key, value);
    // store expiry separately, etc.
  }
  @override Future<void> delete(String key) => Hive.box('cache').delete(key);
  @override Future<void> clear()            => Hive.box('cache').clear();
}

ApiCache.storage = HiveCacheStorage();
