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?

  @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)
    ),
  }
