Detect if OS dark mode is active

I am looking a way to detect if OS dark mode is active, using Flutter. I just want my app to follow the OS dark mode setting. I've googling it and most of the topics are about "setting & switching" dark mode, not about detect the OS' dark mode.

Solution

  • You can use platformBrightness to detect current mode of OS

    bool isDarkMode() {
    final darkMode = WidgetsBinding.instance.platformDispatcher.platformBrightness;
    if (darkMode == Brightness.dark) {
      return true;
    } else {
      return false;
    }
  }
