What is the correct way to add date picker in flutter app?
A simple app showcasing its use:
import 'dart:async';
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
DateTime selectedDate = DateTime.now();
Future<void> _selectDate(BuildContext context) async {
final DateTime? picked = await showDatePicker(
context: context,
initialDate: selectedDate,
firstDate: DateTime(2015, 8),
lastDate: DateTime(2101));
if (picked != null && picked != selectedDate) {
setState(() {
selectedDate = picked;
});
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text("${selectedDate.toLocal()}".split(' ')[0]),
SizedBox(height: 20.0,),
RaisedButton(
onPressed: () => _selectDate(context),
child: Text('Select date'),
),
],
),
),
);
}
}
And a Dartpad with it:

Flutter provides showDatePicker
function to achieve this. It is part of flutter material library.
You can find complete documentation at showDatePicker.
You can also find implemented example here: Date and Time Picker
Simple way is use CupertinoDatePicker class:
First import its package which building in flutter:
import 'package:flutter/cupertino.dart';
Then just add this widget in your form:
Container(
height: 200,
child: CupertinoDatePicker(
mode: CupertinoDatePickerMode.date,
initialDateTime: DateTime(1969, 1, 1),
onDateTimeChanged: (DateTime newDateTime) {
// Do something
},
),
),
The result will be as this image:
Also you can change mode to (dateAndTime,time)... for example this for dateAndTime mode:
Container(
height: 200,
child: CupertinoDatePicker(
mode: CupertinoDatePickerMode.dateAndTime,
initialDateTime: DateTime(1969, 1, 1, 11, 33),
onDateTimeChanged: (DateTime newDateTime) {
//Do Some thing
},
use24hFormat: false,
minuteInterval: 1,
),
),
The result will be as this image:
