This video shows how to use slivers in Flutter Web. Sliver (flutter) is a portion of a scrollable area.
You have possibly the entire control for implementing a scrollable area while using them. Because slivers can lazily build, they are particularly useful for scrolling through a large number of children.
How to use Slivers?
Just as you use, let’s say, SingleChildScrollView for implementing a normal scrolling behavior, in terms of Slivers, you simply wrap your children inside a CustomScrollView

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:
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 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.
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
DatePicker with support for date range and time picker with the new style.
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.
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.
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.
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
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.

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.
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.
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
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.

Recently Adobe XD releases a new version of the plugin that you can use to export designs directly into flutter widgets or screens. Yes, you read it right, now you can make and export your favorite design in Adobe XD and export all the design in the widget form or as a full-screen design, this can save you a lot of time required in designing.
What we will do?
I will make a simple design of a dialogue box with a card design with text over it as shown below. After you complete this exercise you can experiment with the UI. You can make your own components or import UI kits available with the Adobe XD.

Many times online the question has been asked “Is flutter good for web”, and what many developers fail to truly understand is that is a very broad and open question and there are many factors that go into saying yes, no or maybe.
While I am most certainly no expert, I have been around the block for a little over a decade and have spent the last 2+ years working with flutter for mobile and web and have learned a few things, both before and during that, that gives me hopefully some useful insight into that question, insight that may help you answer that question for yourself.
The main problems that is highlighted is SEO, and the justifications given for that are Search Indexing capability or lack thereof , and Performance, which are very valid concerns in general, but there is actually more to it than that.
Let’s start with what is probably the most thrown around is the concern, that Flutter for the web is bad for indexing, as Flutter paints with canvas, it cannot be scrapped by current web scrapers (bots), however, I feel that most of the people screaming this from the rooftops have little to no understanding of what that actually means and seem to feel that your website is the one and the only thing you need to concern yourself when evaluating SEO and search rankings, which is impossibly far from the truth, that would be like saying that the sun would make a good holiday destination.
SEO is a massive thing, you could almost think about it as a living organism that evolves and grows with every interaction and encounter through its journey through the “world”. Search engines are constantly evolving their algorithms and scaling up their scrapers/bots to get the most accurate information possible, filter out the fake and the garbage and tailor the search results to be as relevant to YOU as they can, and this is even more so when it comes to Google.
Google has been keeping tabs on you for years, if not decades, it probably knows you better than you do yourself, and when using it, you are one of the biggest factors it considers when it considers how relevant a result is.

Flutter Web has a big problem.
You like Flutter, but then you know that Flutter is not well optimized and has some problems with SEO.
Check this out! I’ll give a few tricks to solve this problem.
For Web Flutter, use the canvas tag! The canvas is a tag used for drawing; it is a really powerful tag. It lets you achieve goals that otherwise are impossible - like complex animations, new ways of interacting with data, etc… ways that are not possible with the standard HTML, CSS, JS at all.
So what’s the problem? All seems good, right?
No bro! The problem is that the search engine has no way to understand how your content is made since it only understands textual content.
Flutter is a great SDK. It saves you a ton of time, so I don’t see why you should use it anymore, I mean, yes, it has this problem, but we can find some workaround to this issue.
Before they solve this problem (it may take a lot of time), let me tell you a workaround.
I would say that when you want to develop for the web, you should take into consideration the project that you want to create!
If you want to create an article-based website like priiimo.com, then you can split your website into 2 parts - the part that will show the articles to serve it with Node, PHP, or other ways, and the hidden part that needs the authorization to do it with Flutter. All the complex part that, for example, contains the management of users, analytics, etc.
What do you think? I’ll give you another Idea. For example, you use Flutter to create a sort of CMS that will generate HTML pages.
In this way, your content will be visible by search engines without problems.
