running a custom JS function from Flutter using webview package

My Flutter app loads a webpage using the webview_flutter package. I have successfully passed info from the webpage to Flutter, using javascriptChannels. I have also successfully run built-in Javascript, from Flutter to the webpage. (Like launching an alert!)

But! How can I execute a Javascript function on the webpagem from Flutter. (Not merely run a built-in Javascript methods?)

Say my webpage has a function called helloWord(), what is the dart code to trigger that function from Flutter?

DOH! I needed to add the "window" object to the front of the function...

So this code did the trick:

_webViewController.runJavascript('window.helloWorld()');

I am posting in case others have this issue.
