Flutter is now the most popular and programmer-friendly cross-platform UI toolkit for developing natively built applications. Flutter update version 3 is now available for use on all desktop platforms with exciting features to boost productivity. Now, let’s dive into what\’s new in Flutter 3.0!

Everything about the latest Flutter 3 update in 2022

1. Flutter Update: How Flutter was launched

Flutter is a Google SDK and UI framework released in 2018 that allows you to create high-quality native interfaces for six different platforms from a single codebase. Since then, Flutter has been upgraded with new functionalities with each release; notable Flutter update releases include:

New functionalities with each release of Flutter

Flutter 3.0 is Google\’s most recent update that is designed to be developed for multiple platforms. With only a single codebase, it has allowed developers to focus on other tasks while entrepreneurs can plan on fresh concepts for the whole market right from the start. Google has given Flutter developers with stable support for macOS and Linux, as well as for apple silicon, remarkable web and mobile refinements

2. Flutter Update: What is new in Flutter 3?

2.1. Firebase support

Firebase, also known as Backend-As-A-Service, provides Flutter developers with hosted backend services such as real-time database, cloud storage, crash reporting and more. By moving the source code and documentation into the core part of the Firebase offering, it has provided Flutter developers with a powerful backend service that helps create more feature-rich mobile apps. 

About 63% of the developers are using Firebase in their applications.

A suite of Flutter plugins, which becomes a fully-supported key part of the Firebase offering, is also developed by Google to reflect Flutter’s persistent growth. Furthermore, Google is working on Firebase Crashlytics to help developers fix the bugs and improve the app’s stability by checking out the errors.

2.2. Flutter casual games toolkit

In the Flutter 3.0 update, Google has introduced the Casual Games Toolkit including templates, guidelines, and tutorials for game developers who want to create and launch casual games from scratch.
As an open-source platform, Flutter enables developers to integrate a range of new and exciting features via this games toolkit, and features such as in-app purchases, play services, Firebase, etc. Developers can also use a single code base to create new games in the smoothest way. Game developers should take a tour of the flame game engine to get more about how flutter works with games.

2.3. MacOS & Linux support

Flutter 3.0 allows developers to create apps for macOS and Linux operating systems. When Flutter was first launched, it supported Android and iOS platforms, which gradually expanded to Windows, Web, and embedded devices. Flutter has been well – appreciated from the developers’ community ever since. 

The spectrum and reach of Flutter have further expanded, thanks to MacOS and Linux support. Besides, Flutter developers are able to build applications for macOS and Linux devices without facing any difficulties. 

2.4. Dart 2.17

Dart SDK has been updated with the new version in Flutter 3.0, which is known as Dart 2.17. All Flutter developers (even though who do not use Flutter) can access these innovations of Dart – the Dart language 2.17. 

Flutter 3 update includes numerous exciting features such as enums and default function override. This makes enums look like custom-written classes.

3, Flutter Update: Flutter 3 vs Flutter 2

Flutter update version 3 is another masterpiece of Google. With Flutter, developers are able to design attractive and personalized UI with just one codebase, allowing them to work effectively and come up with more successful ideas.

Moreover, Flutter 3.0 also creates iterative live coding, with hot reloading and the ability to run many copies of the application together. The biggest aim of Flutter 3.0 is to give the developers the freedom to get the hidden operating system to its full potential while sharing as much UI as they want. 

4, Flutter Updates in Web and Mobile Application 

4.1, Web Updates

  • Web App lifecycle

Lifecycle API – which is introduced for web applications, can help developers get the flexibility and control over the bootstrap process of Flutter apps from hosting an HTML page. Moreover, we can assess the performance of the app in actual time so that helpful ideas are offered as required. 

  • Image Decoding

It is among the most important updates for the web version by Flutter. Flutter web is now identified and able to use the imagecoder API in the browser. This Flutter update version decodes images with the speed by 2x, ensuring that the crucial series can not be impeded and getting rid of the trash that accumulated in the past.

4.2, Mobile Updates

  • iOS Variable Refresh Rate Support

Flutter 3 update will support the developers on iOS devices with a variety of variable refresh rates, as well as iPhone 13 pro, iPad pro and ProMotion display. Flutter apps can function at 120 hz refresh rates, twice as much as they used to be on these devices. This growth in hz would become smoother during animations. 

  • Foldable Phone Support

Most foldable mobile devices have support from Flutter 3.0 by cooperating with Microsoft. In addition, Flutter developers can utilize MediaQuery class and allocate rules for DisplayFeatures, processing the information regarding various device components like folds, hinges, cutouts, and more. As a result, developers can have dynamic and valuable experiences on foldable devices. 

  • Streamlined iOS Releases

Nowadays, Flutter 3 is using the IPA command, an integrated security information management solution based on 389 Directory Server, to launch IOS releases without having to open X-Code. 

With Flutter update version 3, developers can release the app directly to the App Store or via TestFlight. If you want to update the app, you can release an additional version, similar to Android apps, where Google Play plays an important role in app distribution and updates.


The future for Flutter is promising as it has created lots of significant experiences in the app industry. Certainly, Flutter 3 update is one of the best technologies that can fulfill the needs of different platforms to offer a satisfying user experience. The community deserves all appreciation for doing this awesome work to help Flutter achieve innovation and help businesses across the world.
