#flutter. How to make that countup package to stop automatically after it's start. The current value at it's stop have to be retrieved and it must be double. Every time it executes, it must start the countup at 0 value.

Use a statefulWidget and Timer to check your counter in real time.

Please can you help, how can I get that done

The realtime state of your count is tracked no where so it is counting blind essentially

i've attached a bolierplate example as @Rishi-Sudhakar suggested to you too to use statefulWidget to keep track

import 'package:flutter/material.dart';
import 'package:countup/countup.dart';
import 'dart:async';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: CountupExample(),
    );
  }
}


class CountupExample extends StatefulWidget {
  @override
  _CountupExampleState createState() => _CountupExampleState();
}

class _CountupExampleState extends State<CountupExample> {
  double _currentValue = 0.0;
  bool _isCounting = true;

  @override
  void initState() {
    super.initState();
    _startCountup();
  }

  void _startCountup() {
    setState(() {
      _isCounting = true;
    });

    Timer(Duration(seconds: 60), () {
      setState(() {
        _isCounting = false;
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Countup Example'),
      ),
      body: Center(
        child: _isCounting
            ? Countup(
                begin: 0,
                end: 100,
                duration: Duration(seconds: 60),
                separator: ',',
                style: TextStyle(fontSize: 20),
                onEnd: () {
                  setState(() {
                    _currentValue = 100.0;
                  });
                },
              )
            : Text(
                'Countup Stopped at: ${_currentValue.toStringAsFixed(2)}',
                style: TextStyle(fontSize: 20),
              ),
      ),
    );
  }
}
