Counter and call duration combination in flutter-CodePudding

int score = 0;
score  = 1;

I wish to add 1 ( = 1) to score when call duration reach 30 seconds just once and reset the score to 0 when call duration is less than 30 seconds.

Text('$score')

and show it like this

import 'package:permission_handler/permission_handler.dart';
import 'package:call_log/call_log.dart';
import 'package:flutter_phone_direct_caller/flutter_phone_direct_caller.dart';

I have imported 3 packages above

void callLogs() async {
  Iterable<CallLogEntry> entries = await CallLog.get();
  for (var item in entries) {
    print(Duration());   <--- Use Duration & if statement to solve but duration not printing
   }
 }

and code I wrote above is not working as I imagined to even start with. What changes can I make for adding and resetting score to work? Please help and thanks in advance

Your code waits for this call to complete so it never runs anything under it:

Iterable<CallLogEntry> entries = await CallLog.get();

You could use the StopWatch object to get the time:

void callLogs() async {

    Stopwatch stopwatch = new Stopwatch()..start();

    Iterable<CallLogEntry> entries = await CallLog.get();
    for (var item in entries) {
        var duration = stopwatch.elapsed;
        print('Duration $duration');
   }
 }

And use setState() to set score:

setState(() { duration > 30 ? score  = 1 : score = 0 });

if you variable score is inside of a widget or in the build method then i think that it set it to the begin value any time you run setState because setState builds the build again and also the widgets that is inside the build.

if that is so then try to make the variable global.

PS: global means that you the variable is outside of your class.
