FieldBindingController(FieldBindingParent parent, FlutterWidgetBinder binder, FieldBindingContext<
T> bindingContext) -
Creates a new FieldBindingController with the given
parent,binder, and context.

-
The widget binder that handles the conversion between data and widgets.
final
-
bindingContext
→ FieldBindingContext<
T> -
