Note: I want to use the stateless widget as in stateful its possible but any idea about achieving this in stateless.Like some sort of dispose function in changeNotifier provider.

ChangeNotifierProvider() and ChangeNotifierProvider.value() is different. ChangeNotifierProvider() will set dispose method by default, but ChangeNotifierProvider.value() won't.

ChangeNotifierProvider({
    Key? key,
    required Create<T> create,
    bool? lazy,
    TransitionBuilder? builder,
    Widget? child,
  }) : super(
          key: key,
          create: create,
          dispose: _dispose,
          lazy: lazy,
          builder: builder,
          child: child,
        );

Any class extended with ChangeNotifier gets an Dispose function you can override.

Example:

class MyClass with ChangeNotifier {
      @override
      void dispose() {
        // dispose your stuff here
        super.dispose();
      }
    }
