Date and Time Picker In Flutter
In this article, we will explore the Date and Time Picker in a flutter. We will not be using any package in this application. We will use some core functions available in flutter to achieve this. We will implement a demo of the Date and Time Picker in your flutter applications.
Table of Contents :
Date And Time Picker
A date and time picker for a flutter, you can choose date/time / date&time in English, Dutch, and any other language you will want, and you can also custom your own picker content.
Demo Module ::
Code Implementation
Create a new dart file called DateTimePicker.dart inside the lib folder.
In this screen, You will be able to choose the date and time by tapping on them in your Application.
Future<Null> _selectDate(BuildContext context) async {
final DateTime picked = await showDatePicker(
context: context,
initialDate: selectedDate,
initialDatePickerMode: DatePickerMode.day,
firstDate: DateTime(2015),
lastDate: DateTime(2101));
if (picked != null)
setState(() {
selectedDate = picked;
_dateController.text = DateFormat.yMd().format(selectedDate);
});
}
Initialize DateTime pickers class.that will save our picked Date.
And in onTap of TextFromField, we call _selectDate function then the show will be shown the picker and save the picked date and time.
InkWell(
onTap: () {
_selectDate(context);
},
child: Container(
width: _width / 1.7,
height: _height / 9,
margin: EdgeInsets.only(top: 30),
alignment: Alignment.center,
decoration: BoxDecoration(color: Colors.grey[200]),
child: TextFormField(
style: TextStyle(fontSize: 40),
textAlign: TextAlign.center,
enabled: false,
keyboardType: TextInputType.text,
controller: _dateController,
onSaved: (String val) {
_setDate = val;
},
decoration: InputDecoration(
disabledBorder:
UnderlineInputBorder(borderSide: BorderSide.none),
contentPadding: EdgeInsets.only(top: 0.0)),
),
),
),
It is just a _selectTime function, as shown down here.
Future<Null> _selectTime(BuildContext context) async {
final TimeOfDay picked = await showTimePicker(
context: context,
initialTime: selectedTime,
);
if (picked != null)
setState(() {
selectedTime = picked;
_hour = selectedTime.hour.toString();
_minute = selectedTime.minute.toString();
_time = _hour + ' : ' + _minute;
_timeController.text = _time;
_timeController.text = formatDate(
DateTime(2019, 08, 1, selectedTime.hour, selectedTime.minute),
[hh, ':', nn, " ", am]).toString();
});}
Initializing TimeOfDay pickers class that will save our picked Time in _selecteTime Function.
On Tapping at TextFormField , We call a _selectTime Function which will show the date & time picker saving the picked time .
InkWell(
onTap: () {
_selectTime(context);
},
child: Container(
margin: EdgeInsets.only(top: 30),
width: _width / 1.7,
height: _height / 9,
alignment: Alignment.center,
decoration: BoxDecoration(color: Colors.grey[200]),
child: TextFormField(
style: TextStyle(fontSize: 40),
textAlign: TextAlign.center,
onSaved: (String val) {
_setTime = val;
},
enabled: false,
keyboardType: TextInputType.text,
controller: _timeController,
decoration: InputDecoration(
disabledBorder:
UnderlineInputBorder(borderSide: BorderSide.none),
// labelText: 'Time',
contentPadding: EdgeInsets.all(5)),
),
),
),
