Línea de trabajo

Start in flutter_cache_manager/lib/src/cache_store.dart at CacheStore._getCacheDataFromDatabase and the unawaited _updateCacheDataInDatabase call. Review the repository updateOrInsert path, then create the isolated cache-hit test described in the issue with a failing update. Done means the metadata failure is observed or handled without an unhandled asynchronous exception while the cached file remains usable.

Descripción

🐛 Bug Report

An iOS production build reported an unhandled SqfliteDatabaseException while displaying a cached network image. SQLite returned code 14 ("unable to open database file") for an UPDATE cacheObject ... WHERE _id = ?. Sentry recorded handled: no via PlatformDispatcher.onError. Image URL, SQL arguments, and user/device identifiers are omitted.

This resembles #494. A distinct concern is the cache-hit path in CacheStore._getCacheDataFromDatabase: it calls _updateCacheDataInDatabase(data!) without awaiting or handling the returned Future. If that write fails, the error can escape independently of the image-loading error path. The call is still present on main: https://github.com/Baseflow/flutter_cache_manager/blob/main/flutter_cache_manager/lib/src/cache_store.dart#L120-L127

The reason iOS could not access the SQLite file in this event is unknown; this report focuses on the unhandled asynchronous update.

Expected behavior

A cache metadata write failure should not produce an unhandled asynchronous exception. The cache manager should handle or surface it through an observed error path while keeping a valid cached file usable where possible.

Reproduction steps

The device event was intermittent in production; I do not have a deterministic device reproduction. An isolated test could create a valid cached file and metadata record, make the repository's updateOrInsert throw, then call CacheStore.getFile after a memory-cache miss. The cache-hit metadata update's Future is currently left unobserved.
