Flutter - How to hide/remove title of BottomNavigationBarItem

Now you can simply disable labels for selected or unselected items:

bottomNavigationBar: BottomNavigationBar(
  showSelectedLabels: false,   // <-- HERE
  showUnselectedLabels: false, // <-- AND HERE
  items: [
    BottomNavigationBarItem(
      icon: Icon(Icons.person),
      title: Text('Personal')
    ),
    BottomNavigationBarItem(
      icon: Icon(Icons.notifications),
      title: Text('Notifications'),
    ),
  ]
  ...
)

...resulting in:

There are two workarounds for this problem, as this feature is not yet implemented.

1. Pass Container(height: 0.0) instead of Text("")
2. Create widget and use it instead of Flutter's bottom navigation. Source.

Update:

Just add this to your BottomNavigationBar

showSelectedLabels: false,
showUnselectedLabels: false,
