In this tutorial, I will show you how to Make a Pomodoro Clock App using Flutter. With this tutorial, you will learn how to use Timer in flutter and we will create a nice looking layout so let's start.
Source code:
first of all, we need to add a 3rd part library for the circular progress bar
inside your "pubspec.yaml" file paste this line inside your dependencies
inside your "pubspec.yaml" file paste this line inside your dependencies
dependencies:
percent_indicator: "^2.1.5"
import 'dart:async';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:percent_indicator/circular_percent_indicator.dart';
void main() => runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home: CountDownTimer(),
)
);
class CountDownTimer extends StatefulWidget {
@override
_CountDownTimerState createState() => _CountDownTimerState();
}
class _CountDownTimerState extends State<CountDownTimer> {
double percent = 0;
static int TimeInMinut = 25;
int TimeInSec = TimeInMinut * 60;
Timer timer;
void _StartTimer(){
TimeInMinut = 25;
int Time = TimeInSec;
double SecPercent = (Time/100) ;
print(SecPercent);
timer = Timer.periodic(Duration(seconds: 1), (timer){
setState(() {
if(Time >0){
Time--;
if(Time % 60 == 0){
TimeInMinut--;
}
if(Time% SecPercent == 0){
if(percent <1){
percent+=0.01;
}else{
percent = 1;
}
}
}else{
percent = 0;
TimeInMinut = 25;
timer.cancel();
}
});
});
}
