ttl_cache_service 1.0.1

High-performance in-memory TTL cache with latency-aware eviction (least fetch time evicted first), stampede protection, and func.getTtlCache() extensions.

1.0.1

• Readability Improvement: Renamed TtlEvictionPolicy.lru to TtlEvictionPolicy.leastRecentlyUsed for descriptive, idiomatic Dart naming.
• Backward Compatibility: Retained @Deprecated('Use leastRecentlyUsed instead') static const lru = leastRecentlyUsed; to guarantee zero breaking changes for existing code.
• Pub.dev Discoverability: Optimized package topics to high-traffic canonical categories (cache, performance, networking, async, ttl).

1.0.0

• Production-ready 1.0.0 release.
• Latency-Aware Eviction (TtlEvictionPolicy.leastFetchTime): Prioritizes keeping expensive, high-latency database and network queries in memory when capacity is reached.
• Function Extensions (func.cache(...)): Intercepts async function tear-offs (0 to 4 arguments) with automatic key generation.
• Named Parameter Ergonomics: Unified getOrFetch(key, fetcher: () => ...) and deterministic TtlCache.buildKey(...).
• Stampede / Thundering-Herd Protection: Coalesces concurrent in-flight requests for the same key.
• Classic LRU Eviction (TtlEvictionPolicy.lru).
• Flexible TTL: Configurable per-entry and default time-to-live.
• Hierarchical Invalidation: Exact key, partial prefix, predicate, and function-wide invalidation (invalidateCache, invalidateAllCache).
• Diagnostics & Metrics: TtlCacheStats tracking hits, misses, hit rate, evictions, and saved latency.
• Zero Dependencies: 100% pure Dart, compatible with Flutter (all platforms), Dart VM, Web, and Server.
