import  'dart:math';

import  'package:future_pool/future_pool.dart';

Future future() async {

  int  seconds  =  Random().nextInt(5) +  1;

  await  Future.delayed(Duration(seconds:  seconds));

  return  seconds;

}

void main() async {

  final results = await FuturePool.allSettled(

    List Function()>.filled(10, () =>  future()),

    maxConcurrency:  3,

    // onFutureCompleted: (result, index) {

    //   if (result.status == SettledStatus.fulfilled) {

    //     print('Future $index fulfilled with value: ${result.value}');

    //   } else {

    //     print('Future $index rejected with reason: ${result.reason}');

    //   }

    // },

    onFutureSuccess: (result, index) {

      print('Future $index fulfilled with value: ${result.value}');

    },

    onFutureFail: (result, index) {

      print('Future $index rejected with reason: ${result.reason}');

    }

  );

  print('Finished all results $results');

  for (var  result  in  results) {

    if (result.status  ==  SettledStatus.fulfilled) {

      print('Fulfilled: ${result.value}');

    } else {

      print('Rejected: ${result.reason}');

    }
