onQtyChanged not firing when TextFormField is edited

[ambstuc]

I listen to onQtyChanged to update a resulting field immediately (i.e. the field is used to edit a percentage of a total value, and I am displaying the result of this on the fly). However, if the TextFormField is edited, it only fires onSubmitted, not onChanged.

I have adapted this and added widget.onQtyChanged?.call(temp); after line 555 of input_qty.dart, and seems to be doing the trick.

I think this issue same issue with #73
