Date&Time Picker Widget – Flutter Widget Guide By Flutter Agency

In this article, we will learn about a simple way to display either date, or time, or Date&Time Picker Widget using library datetime_picker_formfield: ^0.1.8  along with how to get the date value and setting initial value.

Dependencies :

There is a package that allows us to easily create either DateTime, date, or time input. At the following to pubspec.yaml and run Get Packages.

datetime_picker_formfield_new: ^2.1.0

A TextFormField that emits DateTimes and helps show Material, Cupertino, and other style picker dialogs.

Fork with support for flutter >3.0.0

Example :

import 'package:datetime_picker_formfield_new/datetime_picker_formfield.dart';
import 'package:flutter/material.dart';
import 'package:intl/intl.dart';

const appName = 'DateTimeField Example';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({
    Key? key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: appName,
      home: const MyHomePage(),
      theme: ThemeData.light().copyWith(
          inputDecorationTheme:
              const InputDecorationTheme(border: OutlineInputBorder())),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  MyHomePageState createState() => MyHomePageState();
}

class MyHomePageState extends State {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(title: const Text(appName)),
        body: SingleChildScrollView(
          child: Center(
              child: Container(
                  constraints: const BoxConstraints(maxWidth: 600),
                  child: const DateTimeForm())),
        ));
  }
}

class DateTimeForm extends StatefulWidget {
  const DateTimeForm({Key? key}) : super(key: key);

  @override
  _DateTimeFormState createState() => _DateTimeFormState();
}

class _DateTimeFormState extends State {
  final formKey = GlobalKey();
  @override
  Widget build(BuildContext context) {
    return Form(
      key: formKey,
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          BasicDateField(),
          const SizedBox(height: 24),
          BasicTimeField(),
          const SizedBox(height: 24),
          BasicDateTimeField(),
        ],
      ),
    );
  }
}

class BasicDateField extends StatelessWidget {
  final format = DateFormat("yyyy-MM-dd");

  BasicDateField({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Column(children: [
      Text('Basic date field (${format.pattern})'),
      DateTimeField(
        format: format,
        onShowPicker: (context, currentValue) {
          return showDatePicker(
              context: context,
              firstDate: DateTime(1900),
              initialDate: currentValue ?? DateTime.now(),
              lastDate: DateTime(2100));
        },
      ),
    ]);
  }
}

class BasicTimeField extends StatelessWidget {
  final format = DateFormat("hh:mm a");

  BasicTimeField({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Column(children: [
      Text('Basic time field (${format.pattern})'),
      DateTimeField(
        format: format,
        onShowPicker: (context, currentValue) async {
          final TimeOfDay? time = await showTimePicker(
            context: context,
            initialTime: TimeOfDay.fromDateTime(currentValue ?? DateTime.now()),
          );
          return time == null ? null : DateTimeField.convert(time);
        },
      ),
    ]);
  }
}

class BasicDateTimeField extends StatelessWidget {
  final format = DateFormat("yyyy-MM-dd HH:mm");

  BasicDateTimeField({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Column(children: [
      Text('Basic date & time field (${format.pattern})'),
      DateTimeField(
        format: format,
        onShowPicker: (context, currentValue) async {
          return await showDatePicker(
            context: context,
            firstDate: DateTime(1900),
            initialDate: currentValue ?? DateTime.now(),
            lastDate: DateTime(2100),
          ).then((DateTime? date) async {
            if (date != null) {
              final time = await showTimePicker(
                context: context,
                initialTime:
                    TimeOfDay.fromDateTime(currentValue ?? DateTime.now()),
              );
              return DateTimeField.combine(date, time);
            } else {
              return currentValue;
            }
          });
        },
      ),
    ]);
  }
}

In the above code snippet, we have used a TextField Widget to display the value of Date Picker or Time Picker or Date & Time Picker Widget. We will get output like below:

Date-Time-Picker

Date&Time Picker Widget 

Date-Time-Picker
