in one of my classes in application i want to pass BlocProvider with class parameter, for example:

enum MenuItems{
  dashboard,
  tutorials,
  logout
}

class DashboardItems {
  MenuItems menuItem;
  BlocProvider action;

  DashboardItems(
      {
        @required this.menuItem,
        @required this.action
      }
  );
}

in that with action field i try to pass this method:

BlocProvider.of<MyEvent>(context).dispatch(MyEvent(event)))

such as:

DashboardItems(
    menuItem: MenuItems.dashboard,
    action:   BlocProvider.of<FragmentBloc>(context).dispatch(FragmentEvent(fragmentHome))),

is any solution to pass and use that?

Looks like you are passing not a function but a result of the function.

DashboardItems(
  menuItem: MenuItems.dashboard,
  // pass function here:
  action: () { BlocProvider.of<FragmentBloc>(context).dispatch(FragmentEvent(fragmentHome));}


class DashboardItems {
  MenuItems menuItem;
  Function action; //Change type from BlocProvider to Function.

  DashboardItems(
      {
        @required this.menuItem,
        @required this.action
      }
  );
}
