The named parameter 'title' isn't defined. Try correcting the name to an existing named parameter's name

Answer 1

BottomNavigationBarItem doesn't have a title parameter anymore. It should be something like this now:

    BottomNavigationBarItem(
      icon: Icon(FontAwesomeIcons.heart),
      label: 'Wish List',
    ),
