zero_cached_image 1.3.0

A minimal, high-performance cached network image widget. Zero-copy disk reads via ImmutableBuffer.fromFilePath, in-memory index, ETag support. Only 2 dependencies.

1.3.0

• ZeroCacheManager now accepts cacheRootOverride constructor param. When set, the cache lives at <cacheRootOverride>/<cacheDirName> instead of <getApplicationSupportDirectory()>/<cacheDirName>. Enables placing the cache inside an iOS App Group container so a Notification Service Extension running in a separate process can read the same files. Defaults to null (1.2.0 behavior preserved).

1.2.0

• ZeroCacheManager.getCachedFilePath(url) — cache-only lookup that returns the local file path if already cached, null on miss. Never downloads. Intended for latency-critical paths (background-isolate notification rendering, etc.) where a network round trip is not acceptable.

1.1.0

• ZeroCacheManager now accepts cacheDirName and extensionAllowlist constructor params. Defaults preserve 1.0.0 behavior (zero_cached_image dir, image-only extension allowlist). Enables sibling packages (e.g., zero_cached_video) to reuse the cache machinery with their own directory + media-type allowlist.

1.0.0

• Initial release.
• ZeroCachedImage widget with fade animations and placeholder/error support.
• ZeroCachedImageProvider for use with DecorationImage and precacheImage.
• ZeroCacheManager with LRU eviction, ETag conditional requests, and Cache-Control max-age.
• Zero-copy image loading via ImmutableBuffer.fromFilePath().
• In-memory index with JSON persistence (survives restarts).
• Concurrent request deduplication.
• Atomic index writes with backup recovery.
• Web fallback via Image.network().
