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.


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.


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.


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. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

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 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.


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





Reflectly app

Abbey Road Studios

Abbey Road Studios

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.

How to Making A Simple Credit Card Validation form

In this quick tutorial we will show you how to create a simple credit card form. We'll build the whole thing from scratch, with a little help from Bootstrap 3 for the interface, and Payform.js for client-side form validation.

Project Overview

Here is a sneak-peak of what we will be building in this tutorial:


Credit Card Form Demo

You can get the full code for this project from the Download button near the top of the article. An overview of the files can be seen below:


There are two .css files and two .js files which we will need to include in our HTML. All other resources such as the Bootstrap framework, jQuery, and web fonts will be included externally via CDN.


<!DOCTYPE html>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Credit Card Validation Demo</title>

    <link href="" rel="stylesheet">
    <link rel="stylesheet" href="">
    <link rel="stylesheet" type="text/css" href="assets/css/styles.css">
    <link rel="stylesheet" type="text/css" href="assets/css/demo.css">


    <!-- The HTML for our form will go here -->

    <script src=""></script>
    <script src="assets/js/jquery.payform.min.js" charset="utf-8"></script>
    <script src="assets/js/script.js"></script>

Now that everything is set up, we can start building our credit card form. Let's start with the HTML layout!


A credit card dialog needs to be simple, short, and straightforward. Here are the four input fields that every credit card form needs to have:

  • Credit card owner name
  • Card number
  • Secret code (also known as CVV/CVC/CID)
  • Expiration Date

All we need to do is create a <form> and add all the required input fields. For the owner, card number, and CVV we will use simple text fields. For the expiration date we'll put a combination of two selects with predefined options.

Besides that our form will have a heading, a submit button, and images for popular credit card vendors. Since we are working with Bootstrap there is a little extra markup, but it helps keep the code organized and the layout responsive.

<div class="creditCardForm">
    <div class="heading">
        <h1>Confirm Purchase</h1>
    <div class="payment">
            <div class="form-group owner">
                <label for="owner">Owner</label>
                <input type="text" class="form-control" id="owner">
            <div class="form-group CVV">
                <label for="cvv">CVV</label>
                <input type="text" class="form-control" id="cvv">
            <div class="form-group" id="card-number-field">
                <label for="cardNumber">Card Number</label>
                <input type="text" class="form-control" id="cardNumber">
            <div class="form-group" id="expiration-date">
                <label>Expiration Date</label>
                    <option value="01">January</option>
                    <option value="02">February </option>
                    <option value="03">March</option>
                    <option value="04">April</option>
                    <option value="05">May</option>
                    <option value="06">June</option>
                    <option value="07">July</option>
                    <option value="08">August</option>
                    <option value="09">September</option>
                    <option value="10">October</option>
                    <option value="11">November</option>
                    <option value="12">December</option>
                    <option value="16"> 2016</option>
                    <option value="17"> 2017</option>
                    <option value="18"> 2018</option>
                    <option value="19"> 2019</option>
                    <option value="20"> 2020</option>
                    <option value="21"> 2021</option>
            <div class="form-group" id="credit_cards">
                <img src="assets/images/visa.jpg" id="visa">
                <img src="assets/images/mastercard.jpg" id="mastercard">
                <img src="assets/images/amex.jpg" id="amex">
            <div class="form-group" id="pay-now">
                <button type="submit" class="btn btn-default" id="confirm-purchase">Confirm</button>

Now that we have the needed input fields, we can setup the validation rules.


All of the validation we will show here is client side and done exclusively in the JavaScript. If it is HTML validation that you are interested in, check out this article.

To kick things off we will define all the jQuery selectors we will need:

var owner = $('#owner'),
    cardNumber = $('#cardNumber'),
    cardNumberField = $('#card-number-field'),
    CVV = $("#cvv"),
    mastercard = $("#mastercard"),
    confirmButton = $('#confirm-purchase'),
    visa = $("#visa"),
    amex = $("#amex");

Then, using Payform.js, we will turn our basic input fields into specialized input for credit card data. We simply need to call the right function and the library will automatically handle text formatting and maximum string length for us:

cardNumber.payform('formatCardNumber'); CVV.payform('formatCardCVC');

Next, we want to be able to give real-time feedback to users while they are typing in their card number. To do so we will write a simple function that does two things:

  1. Check if the current text in the field is а valid card number or not. Add appropriate coloring to the text field.
  2. Depending on the present input characters, see if the card is either Visa, MasterCard, or American Express. This is done using the payform.parseCardType() method.

Since we want to execute the above actions every time a new character is typed in, we will use the jQuery keyup() event listener.

cardNumber.keyup(function() {

    if ($.payform.validateCardNumber(cardNumber.val()) == false) {
    } else {

    if ($.payform.parseCardType(cardNumber.val()) == 'visa') {
    } else if ($.payform.parseCardType(cardNumber.val()) == 'amex') {
    } else if ($.payform.parseCardType(cardNumber.val()) == 'mastercard') {

There is one more thing we have to do and that is is check if all the field are holding valid data when the user tries to submit the form.

Name validation can be quite tricky. To keep this tutorial light, we won't be going into that subject, and we will only check if the input name is at least 5 characters long. Payform provides us with the needed methods for validating the rest of the form. {

    var isCardValid = $.payform.validateCardNumber(cardNumber.val());
    var isCvvValid = $.payform.validateCardCVC(CVV.val());

    if(owner.val().length < 5){
        alert("Wrong owner name");
    } else if (!isCardValid) {
        alert("Wrong card number");
    } else if (!isCvvValid) {
        alert("Wrong CVV");
    } else {
        // Everything is correct. Add your form submission code here.
        alert("Everything is correct");

The above validation is for educational purposes only and shouldn't be used on commercial projects. Always include both client-side and server-side validation to your forms, especially when working with credit card data.


We are using Bootstrap, so most of the styling is done by the framework. Our CSS mostly covers the size of the input fields and various padding, margin and font tweaks.


.creditCardForm {
    max-width: 700px;
    background-color: #fff;
    margin: 100px auto;
    overflow: hidden;

    margin-top: 25px;
    text-align: right;
.creditCardForm #pay-now {
    width: 100%;
    margin-top: 25px;
.creditCardForm .payment .btn {
    width: 100%;
    margin-top: 3px;
    font-size: 24px;
    background-color: #2ec4a5;
    color: white;
.creditCardForm .payment select {
    padding: 10px;
    margin-right: 15px;
.transparent {
    opacity: 0.2;
@media(max-width: 650px) {
    .creditCardForm .owner,
    .creditCardForm .CVV,
    .creditCardForm #expiration-date,
    .creditCardForm #credit_cards {
        width: 100%;
    .creditCardForm #credit_cards {
        text-align: left;

With this our Credit Card Validation Form is complete!
