CachedManager<M> class abstract

An abstract class responsible for managing cached files in the application.

The CacheManager<T> provides the contract for caching images and other assets locally to enhance performance and reduce redundant network requests. It defines methods for retrieving local files, cache cleanup, and pre-caching assets.

Subclasses should implement platform-specific caching mechanisms.

Properties:

• cacheCleanupThreshold (Duration):
  • The duration after which cached files are considered stale and eligible for deletion. Default is set to 7 days.

Methods:

• CacheManager({Duration cacheCleanupThreshold}):

  • Constructs an instance of the CacheManager class with an optional cache cleanup threshold.

• Future<T> getLocalFile(String url):

  • Retrieves a local file corresponding to the specified URL.

• Future<void> preCacheAsset(String assetPath):

  • Pre-caches an asset from the application's bundle into the temporary directory.

Implementers

• UniversalCachedManager
• WebCachedManager
