flutter_media_cache 2.0.1

A powerful Flutter package for caching images and videos with customizable expiration time and automatic cache management.

Changelog

2.0.1 — 2026-06-25

✨ New Features

• Web platform support — package now works on all 6 Flutter platforms: Android · iOS · Web · macOS · Windows · Linux.
• MediaCacheManager.formatBytes(int) utility for human-readable cache sizes.
• MediaCacheManager.totalCacheSize getter (memory bytes on web, disk bytes on native).

🔧 Improvements

• CachedVideo on web uses VideoPlayerController.networkUrl() automatically — no code changes needed in calling code.
• All disk I/O isolated behind PlatformStorage conditional-import abstraction; dart:io is never imported on web.
• CacheIndex rewritten to be dart:io-free (serialises via Uint8List).
• Orphaned file cleanup (purgeOrphans) runs at startup on native platforms.

🐛 Bug Fixes

• Fixed: Package failed to compile on Flutter Web due to dart:io imports in media_cache_manager.dart and cached_video.dart.
• Fixed: CachedVideo crashed on web with "Video file path unavailable".
• Fixed: pub point issues.

2.0.0 — 2026-06-25

⚠️ Breaking Changes

• Complete rewrite — public API is redesigned. See README for migration guide.
• FlutterMediaCache class replaced by MediaCacheManager singleton.
• CachedImage constructor parameters reorganised (imageUrl replaces url).

✨ New Features

• Priority download queue — DownloadPriority.high/normal/low per request.
• Request deduplication — duplicate URLs share one in-flight download.
• Exponential-backoff retry — configurable via CacheConfig.maxRetries.
• Per-download progress stream — Stream<DownloadProgress> with bytes received.
• Conditional HTTP GET — ETag / Last-Modified / If-None-Match support.
• Smart LRU eviction — separate memory (item count) and disk (byte size) limits.
• Preloading API — MediaCacheManager.instance.preloadAll([...]).
• Cancellation — cancelDownload(url) stops queued or in-flight tasks.
• CachedVideo widget with built-in progress indicator and playback controls.
• DownloadProgressBuilder for fully custom progress UIs.
• CacheManagerProvider InheritedWidget for dependency injection.
• CacheStats — hit count, miss count, eviction count, hit rate, total size.
• Atomic index persistence — write-then-rename prevents index corruption.
• Orphan file cleanup — dangling files not in the index are removed on startup.

🔧 Improvements

• Cache keys now use SHA-256 (not MD5) for collision-resistance.
• Download engine lives on the main isolate with async/await — no Isolate overhead for small payloads, correct Flutter API access.
• CacheConfig.copyWith() for easy per-screen overrides.
• Debounced index writes (2 s) — avoids disk thrash on rapid requests.
• ResizeImage support in CachedImage to reduce decoded memory footprint.

🐛 Bug Fixes

• Fixed: Concurrent requests for the same URL triggered multiple downloads.
• Fixed: Memory cache could grow unboundedly.
• Fixed: Download failures were silently swallowed.
• Fixed: Stale index entries for missing files caused errors.
