As per SO post : https://stackoverflow.com/questions/66027441/error-method-not-found-buttontheme-bar

ButtonTheme.bar is Deprecated. We need to use ButtonBarTheme instead which offers more flexibility to configure ButtonBar widgets. This feature was deprecated after v1.9.1.

So need to change

to

final Widget actions = new ButtonBarTheme(

on line 506 of flutter_duration_picker.dart

I am happy to submit PR for the same.
