bottom navbar example from flutter documentation

      ),

      ),
    ],
    currentIndex: _selectedIndex,
    selectedItemColor: Colors.amber[800],
    onTap: _onItemTapped,
  ),

Solution

1. Create a custom class

    class MyTabItem {

    String title;
    IconData icon;

    MyTabItem(this.name, this.icon);

    }

2. Create list of tabs:

List<MyTabItem> _items = [
  MyTabItem('Home', Icons.home),
  MyTabItem('Business', Icons.business),
  MyTabItem('School', Icons.school),
];

3. Create a method to iterate through the _items collection and returns List<BottomNavigationBarItem>

List<BottomNavigationBarItem> getBottomTabs( List<MyTabItem> tabs) {
    return tabs
        .map(
          (item) =>
          BottomNavigationBarItem(
            icon: Icon(item.icon),
            label: item.title,
          ),
    )
        .toList();
  }

4. Finally, call the method:

bottomNavigationBar: BottomNavigationBar(
          items: getBottomTabs(items),
         ),
