Hi @king2636 ,

I'm not sure if that's exactly what you're looking for, but here's an example of a Dart implementation of it. You can check how it works using an online compiler with an integrated terminal such as Online Dart Compiler:

import 'dart:async';
import 'dart:io';
import 'dart:math';

void main() {
  Counter counter = Counter();
  counter.startCounter();

  // Event listener for stopping and restarting the counter when pressing a key 
  stdin.listen((_) {
    counter.stopCounter();
    counter.startCounter();
  });
}

class Counter {
  int _counter = 0; 
  Timer? _timer; 
  final Random _random = Random(); 

  void startCounter() {
    // Set the counter to a random value between 0 and 999 (you can change it to whatever value you prefer)
    _counter = _random.nextInt(1000);  
    _timer = Timer.periodic(Duration(milliseconds: 100), (timer) {
      _counter++;
      print('Counter: $_counter');
    });
  }

  void stopCounter() {
    if (_timer != null && _timer!.isActive) {
      _timer?.cancel();
      // Stops the counter and prints the value when pressing a key
      print('Stopped at: $_counter');
    }
  }
}

I want the counter to be like that one in the sample above
