How to automatically fill a form on the loaded page?

Hi,
I want to be able to automatically fill a form on the page I am loading, with values from my application.

Is there a way to do this? perhaps injecting some JS code in the page, or having access to the page's DOM after it loads...

Any ideas will be appreciated.

Start by reading the plugin's existing Flutter-to-native WebView communication entry points and checking whether page JavaScript or DOM access is already exposed. Define whether the requested form filling needs JavaScript injection, DOM access, or both, then verify the chosen approach on a loaded page and document the supported behavior.
