The Flutter Cupertino Date Picker is a delightful way to enhance your Dart application by allowing users to select dates and times easily. In this guide, we’ll walk through the necessary steps to integrate this widget into your Flutter project. So, roll up your sleeves, and let’s get started!

1. Depend on the Package

To include the Flutter Cupertino Date Picker in your project, you first need to add it as a dependency in your `pubspec.yaml` file:

dependencies:
  flutter_cupertino_date_picker: ^1.0.26+2

2. Install the Package

After adding the dependency, you need to run the following command in your terminal to install it:

$ flutter packages get

3. Import the Package

To use the Cupertino Date Picker in your Dart code, you must import it. Add the following line to your Dart file:

import 'package:flutter_cupertino_date_picker/flutter_cupertino_date_picker.dart';

4. Displaying the Date Picker

You can display the date picker either in a bottom sheet or as a widget. Let’s explore these two methods.

Bottom Sheet Date Picker

To present the date picker as a bottom sheet, use the following function:

DatePicker.showDatePicker(
  BuildContext context,
  DateTime minDateTime,
  DateTime maxDateTime,
  DateTime initialDateTime,
  String dateFormat,
  {DateTimePickerLocale locale = DATETIME_PICKER_LOCALE_DEFAULT,
  DateTimePickerMode pickerMode = DateTimePickerMode.date,
  DatePickerTheme pickerTheme = DatePickerTheme.Default,
  DateVoidCallback onCancel,
  DateVoidCallback onClose,
  DateValueCallback onChange,
  DateValueCallback onConfirm,});

Analogous Explanation

Think of integrating a date picker like setting up a beautiful café. You need to establish the right framework (installation and import). Next, choose how you want to serve coffee (bottom sheet or widget). Finally, you pick the right ambiance (theme and locale) to enhance the overall experience for your guests. Just like the perfect cup of coffee, the details in the date picker make all the difference.

5. Supported Locales

The date picker comes with support for various languages, enhancing its international usability:

• en_us: English (United States) (Default locale)
• ar: Arabic
• es: Spanish
• fr: French
• …and many more!

6. Customizing the Date Time Picker Theme

You can customize the appearance of the date picker by modifying the theme parameters:

const DateTimePickerTheme(
  this.backgroundColor,
  this.cancelTextStyle,
  this.confirmTextStyle,
  this.cancel,
  this.confirm,
  this.title,
  {this.showTitle = true,
  this.pickerHeight,
  this.titleHeight,
  this.itemHeight,
  this.itemTextStyle,});
