Expose the method of clearing the cache

I'm using the plugin, but at some point I need to clear the webview cache, so I'd like, if possible, expose the method of clearing the cache, so I can use it wherever I am and however I want, without having to go through launch().

But if there is another way to clear the cache without using launch, please let me know how.
Thanks for listening and for the support.

The request concerns the plugin's launch() path and its existing webview-cache clearing behavior; start by locating that entry point and the cache operation on the Flutter and native sides. Define the public API boundary and verify that clearing can be invoked without launch(), then check any existing tests or manual behavior available in the repository.
