Future.delayed would be a good solution without a countdown.

But considering you have a countdown, you can use the animation framework Flutter provides.

The idea behind it would be to use an AnimationController with a duration of 3 seconds. Start the animation as soon as the splashScreen is instantiated. And add a listener to redirect to /login on animation end.

Then pass that controller to an AnimationBuilder which would handle the formating of your countdown based on animationController.lastElaspedDuration.

class SplashScreen extends StatefulWidget {
  final Duration duration;

  const SplashScreen({this.duration});

  @override
  _SplashScreenState createState() => new _SplashScreenState();
}

class _SplashScreenState extends State with SingleTickerProviderStateMixin {
  AnimationController animationController;

  @override
  void initState() {
    animationController = new AnimationController(duration: widget.duration, vsync: this)
      ..forward()
      ..addStatusListener((status) {
        if (status == AnimationStatus.completed) {
          Navigator.pushReplacementNamed(context, '/login');
        }
      });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return new AnimatedBuilder(
      animation: animationController,
      builder: (context, _) {
        return new Center(
          child: new Text(animationController.lastElapsedDuration.inSeconds.toString()),
        );
      },
    );
  }
}
