For Android, this plugin’s main function is to clear webView cache and all files within the app’s cache directories and code cache directory. This plugin will delete all files within output paths of functions getCacheDir(), getExternalCacheDir(), and getCodeCacheDir() under Context library.

For iOS, this plugin clears the web resources cache of the application (in-memory and on-disk).
