Flutter inherit all props from parent widget

Question

I want to make custom button on flutter. here is some code:

// class LoadingButton.dart

MaterialButton(
  padding: EdgeInsets.all(Spacing().value(2)),
  textColor: Colors.white,
  disabledColor: Colors.grey[100],
  ...props
);

How can I add props dynamically without stating constructor one by one?

I've tried using ...props but it wont add to the props.

Thanks

There is no such thing in Dart. Only copy-pasting all properties will work.
