Usage


// works without any param
PhoneFormField();

// all params
PhoneFormField(
  key: Key('phone-field')
  controller: null,     // controller & initialValue value
  initialValue: null,   // can't be supplied simultaneously
  shouldFormat: true    // default 
  defaultCountry: IsoCode.US, // default 
  decoration: InputDecoration(
    labelText: 'Phone',          // default to null
    border: OutlineInputBorder() // default to UnderlineInputBorder(),
    // ...
  ),
  validator: PhoneValidator.validMobile(),   // default PhoneValidator.valid()
  isCountryChipPersistent: false, // default
  isCountrySelectionEnabled: true, // default
  countrySelectorNavigator: CountrySelectorNavigator.bottomSheet(),
  showFlagInInput: true,  // default
  flagSize: 16,           // default
  autofillHints: [AutofillHints.telephoneNumber], // default to null
  enabled: true,          // default
  autofocus: false,       // default
  onSaved: (PhoneNumber p) => print('saved $p'),   // default null
  onChanged: (PhoneNumber p) => print('saved $p'), // default null
  // ... + other textfield params
)

Validation

Built-in validators

  • required : PhoneValidator.required
  • valid : PhoneValidator.valid (default value when no validator supplied)
  • valid mobile number : PhoneValidator.validMobile
  • valid fixed line number : PhoneValidator.validFixedLine
  • valid type : PhoneValidator.validType
  • valid country : PhoneValidator.validCountry
  • none : PhoneValidator.none (this can be used to disable default valid validator)

Validators details

  • Each validator has an optional errorText property to override built-in translated text
  • Most of them have an optional allowEmpty (default is true) preventing to flag an empty field as valid. Consider using a composed validator with a first PhoneValidator.required when a different text is needed for empty field.

Composing validators

Validator can be a composed set of validators built-in or custom validator using PhoneValidator.compose, see example below.

Note that when composing validators, the sorting is important as the error message displayed is the first validator failing.

PhoneFormField(
  // ...
  validator: PhoneValidator.compose([
    // list of validators to use
    PhoneValidator.required(errorText: "You must enter a value"),
    PhoneValidator.validMobile(),
    // ..
  ]),
)

Country selector

Here are the list of the parameters available for all built-in country selector :

NameDefault valueDescription
countriesnullCountries available in list view (all countries are listed when omitted)
favoritesnullList of country code ['FR','UK'] to display on top of the list
addSeparatortrueWhether to add a separator between favorite countries and others one. Useless if favorites parameter is null
showCountryCodetrueWhether to display the country dial code as listTile item subtitle
sortCountriesfalseWhether the countries should appear in alphabetic order, if false the countries are displayed in the same order as countries property (Note that favorite countries are listed in supplied order whatever the value of this parameter)
noResultMessagenullThe message to be displayed in place of the list when search result is empty (a default localised message is used when omitted)

Built-in country selector

CountrySelectorNavigator.searchDelegate Open a dialog to select the country. No extra parameters

CountrySelectorNavigator.dialog Open a dialog to select the country. No extra parameters

CountrySelectorNavigator.bottomSheet Open a bottom sheet expanding to all available space in both axis No extra parameters

CountrySelectorNavigator.modalBottomSheet Open a modal bottom sheet expanded horizontally Extra parameters:

  • height (double, default null) Allow to determine the height of the bottom sheet, will expand to all available height when omitted

CountrySelectorNavigator.draggableBottomSheet Open a modal bottom sheet expanded horizontally which may be dragged from a minimum to a maximum of current available height. Uses internally the DraggableScrollableSheet flutter widget Extra parameters:

  • initialChildSize (double, default: 0.5) factor of current available height used when opening
  • minChildSize (double, default: 0.Z5) : maximum factor of current available height
  • minChildSize (double, default: 0.Z5) : minimum factor of current available height
  • borderRadius (BorderRadiusGeometry, default: 16px circular radius on top left/right)

Custom Country Selector Navigator

You can use your own country selector by creating a class that implements CountrySelectorNavigator It has one required method navigate expected to return the selected country:

class CustomCountrySelectorNavigator implements CountrySelectorNavigator {
  Future<Country?> navigate(BuildContext context) {
    // ask user for a country and return related `Country` class
  }
}

// usage
PhoneFormField(
  // ...
  selectorNavigator: CustomCountrySelectorNavigator(),
  // ...
)

Internationalization

Include the delegate

    return MaterialApp(
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        PhoneFieldLocalization.delegate
      ],
      supportedLocales: [
        const Locale('en', ''),
        const Locale('es', ''),
        const Locale('fr', ''),
        const Locale('ru', ''),
        const Locale('uk', ''),
        // ...
      ],

That's it.

A bunch of languages are built-in:

- 'ar',
- 'de',
- 'en',
- 'el'
- 'es',
- 'fr',
- 'hin',
- 'it',
- 'nl',
- 'pt',
- 'ru',
- 'uk',
- 'tr',
- 'zh',
- 'sv',

If one of the language you target is not supported you can submit a pull request with the translated file in src/l10n

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add phone_form_field

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  phone_form_field: ^7.0.2

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:phone_form_field/phone_form_field.dart'; 

example/lib/main.dart

import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:phone_form_field/phone_form_field.dart';

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

// this example makes uses of lots of properties that would not be there
// in a real scenario for the sake of showing the features.
// For a simpler example see the README

Flutter Phone Input Integrated with Flutter Internationalization

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more.

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

flutter-mobile-desktop-web-embedded_min

Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.

humming_bird_dart_flutter

Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are
