Answer 1

the problem was for set changeNotifierProvider in on up level but is use in higher level multi provider in main.dart file i removed changeNotifierProvider in one up level problem solved thanks guys

when face with these problems like this just go one up level and remove ChangeNotifierProvider for example

body: ChangeNotifierProvider(
          create: (ctx) => YOUR_PROVIDER_CLASS_NAME(),
          child: Container(
            child: YOUR_WIDGER(
          ),
        ));

and leave Container alone for this example but you should use multi provider in highest level before
