What you'd like to happen

I can't find anything on this, or if there is a way that I'm not seeing, but essentially just allow lists of items.

Something like

FormBuilderList<String> (
    name: name,
    icon: Icons.add,
    etc...
)

and

FormBuilderDropdownList<String> (
    name: name,
    icon: Icons.add,
    etc...
)

Where when you tap/click the icon you add another item to the list.

or maybe

FormBuilderList (
    icon: Icons.add,
    child: FormBuilderDropDown(
    )
)

so it knows what type of form field to add when you click the add button. I think that option is better possibly.
