FAQ #
My phone's notch is overlapping with BottomBar. How do I fix this? #

Simply wrap BottomBar with a SafeArea widget.

How do I change the overall color of BottomBarItem when in dark mode? #

You can use PlatformBrightness to check dark mode and adjust the color accordingly.

@override
Widget build(BuildContext context) {
bool isDarkMode = MediaQuery.of(context).platformBrightness == Brightness.dark;

BottomBarItem(
activeColor: isDarkMode ? Colors.orange : Colors.blue, // Is dark mode true? (Yes -> Colors.orange | No -> Colors.blue)
),
}
