Additional information

This package provides a unified way to manage cache in Flutter applications across both Android and iOS platforms. The cache management is achieved through a combination of Flutter and native code.

Android Cache Management

Android cache management is handled entirely within the Flutter environment. The package leverages the getTemporaryDirectory method from the path_provider package to access and manage the Android cache directory. The methods provided by the package are platform-agnostic and work seamlessly on Android.

iOS Cache Management

For iOS cache management, native Swift code is used to interact with the cache system. The package includes a Swift bridge that communicates with the Flutter environment through method channels. This approach ensures efficient and accurate cache management on iOS devices.
