You can have list of cities and list of times or you can even generate time based on present time.

Sample code:

class MyApp extends StatelessWidget {
  final cities = ['Amsterdam', 'The Hague', 'Rotterdam', 'Utrecht', 'Groningen'];

  @override
  Widget build(BuildContext context) {
    final random = Random(); // You can use random to generate random cities
    final city = cities[random.nextInt(cities.length)];
    final time = DateTime.now().add(Duration(minutes: random.nextInt(60 * 24)));

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Random City')),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              Text(city, style: TextStyle(fontSize: 32)),
              SizedBox(height: 16),
              Text('${time.hour.toString()}:${time.minute.toString()}'),
            ],
          ),
        ),
      ),
    );
  }
}
