Cupertino Timer Picker is IOS style timer picker in flutter, that allows user to search a duration of time or a time interval. In this Flutter Article let’s learn how to implement CupertinoTimerPicker in flutter with complete source code.

If you’re looking for a Cupertino-style timer picker i.e ios style time picker, then flutter provide a Timer Picker widget in Material Design class named CupertinoTimerPicker Here’s a basic example of how you can create a Cupertino-style timer picker:

We can make use of showCupertinoModalPopup widget to show a popup from the bottom of the screen.

Creating the Timer Picker Widget:

We have a function _showTimerPicker that open a popup at the bottom of the screen and displays the Timer Picker when a user press on a button to select a time duration user can select time in hours, minutes and seconds, To show type of mode that i.e. hms we can make use of mode property from CupertinoTimerPicker widget.

snippet – CupertinoTimerPacker Widget constructor

 Key? key,
 CupertinoTimerPickerMode mode = CupertinoTimerPickerMode.hms,
 Duration initialTimerDuration = Duration.zero,
 int minuteInterval = 1,
 int secondInterval = 1,
 AlignmentGeometry alignment = Alignment.center,
 Color? backgroundColor, 
 double itemExtent = _kItemExtent, 
 required ValueChanged<Duration> onTimerDurationChanged

Handling Timer Selection and displaying selected time in Text Widget

The selected duration is stored in the selectedDuration variable initially it will be 0 for hours,minutes and seconds duration, When the user selects a new duration from Cupertino Timer Picker, the onTimerDurationChanged callback is triggered which has callback duration value selected using which we can update the selectedDuration using setState to reflect the user’s selection.

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      home: const MyHomePage(),

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  State<MyHomePage> createState() => _MyHomePageState();

class _MyHomePageState extends State<MyHomePage> {

  Duration selectedDuration = Duration(hours: 0,minutes: 0,seconds: 0);

  void _showTimerPicker(BuildContext context){
        context: context,
        builder: (BuildContext context){
          return Container(
            height: 200,
            color: CupertinoColors.white,
            child: Column(
              children: [

                      initialTimerDuration: selectedDuration,
                      onTimerDurationChanged:  (Duration duration){
                       setState(() {
                         selectedDuration = duration;
  Widget build(BuildContext context) {
