Bottom Navigation Bar Code

Answer 1

In your BottomNavigationBar there's an items property:

Scaffold(
        bottomNavigationBar: BottomNavigationBar(items: [
      BottomNavigationBarItem(icon: Icon(Icons.home), label: 'Home'),
    ]));

this property accepts a List<BottomNavigationBarItem>. Now, the length of this list should be at least 2.

For example:

Scaffold(
      bottomNavigationBar: BottomNavigationBar(items: [
        BottomNavigationBarItem(icon: Icon(Icons.home), label: 'Home'),
        BottomNavigationBarItem(icon: Icon(Icons.search), label: 'search'),
      ]),
    );

but your providing only one BottomNavigationBarItem, so make sure you have at least one more BottomNavigationBarItem
