I'm using the Screenshot package to capture a screenshot of my custom widget and save the image to a page state variable. I have it working just fine, but only because I'm calling the capture method from within the widget with a button.
I would like to do the capture from an existing button on the page.
I used these two videos to help me initially, but they both initiate the capture from inside the widget, not from a custom action:

I tried initializing the screenshot controller in a custom action and using that in main.dart.
When I call the method in my widget, the compiler says it's not defined.
