  backgroundColor: Colors.red,
  badgeShape: BottomNavigationBadgeShape.circle,
  textColor: Colors.white,
  position: BottomNavigationBadgePosition.topRight,
  textSize: 8);

Create a list of BottomNavigationBarItems

List<BottomNavigationBarItem> items = [
  BottomNavigationBarItem(icon: Icon(Icons.home), title: Text("Home")),
  BottomNavigationBarItem(icon: Icon(Icons.notifications), title: Text("Notifications")),
  BottomNavigationBarItem(icon: Icon(Icons.face), title: Text("Profile"))
];

Add badge to index with content "1"

setState(() {
  items = badger.setBadge(items, "1", index);
});

Remove the badge at index

setState(() {
  items = badger.removeBadge(items, index);
});

Remove all the badges

setState(() {
  items = badger.removeAll(items);
});
