How to extend the Focus Class?

Flutter and FlutterFlow can make you feel as though you have never touched a computer before in your life.

#1. Flutter left the focus issue unfinished... Therefore FlutterFlow left it unfinished by default. Every single clickable widget should have a Focus parameter.

Can someone help me extend the Flutter Focus Class properly so that FlutterFlow will accept a Widget as the child parameter?

For No reason that I can see, Some widgets do not have a FocusNode Property, such as DropDownMenus. I have a case where I now need to WRAP my dropdown with a Custom Focus Widget.

I'm only guessing that I can extend the Focus Class and do nothing more than send it my DropDown Widget as a child parameter....

However, I am not smart enough to code this in this codeless environment... Below is my initial failing class extension... It is a Custom Widget that does nothing more than ATTEMPT to extend the focus class....:

No compile errors (on this version)....
