Google launched the Flutter 2.2 version last year at Google I/O. After the release of this version, there has been a couple of upgrades and other stable releases to Flutter. The new version that came live after this is Flutter 3.0 with several updates and improvements. Previously Flutter App Development revealed support only for windows but now Flutter has version 3 which is compatible with macOS and Linux along with windows.

Many additional features like speed optimization, widgets, integration support, and many other improvements have been added in this version for mobile app development and this has made Flutter more compatible with the cross-platform framework.

Top Highlights of Flutter 3.0

Improved Performance

Well, one of the highlights that Flutter 3 has launched is its support for six different platforms Mobile, Desktop, Web, Windows, macOS, and Linux.

It allows Flutter app developers to work efficiently and effortlessly and also increases their productivity as they can design personalized and attractive UI by using the same codebase for all these six different platforms.

Firebase Integration

Firebase comes under the category of backend Flutter app development services. It provides developers with all the backend services such as cloud storage, data authentication, device testing, and more. The firebase’s core integration with the platform becomes more robust and powerful with the introduction of the Flutter 3.0 version.

Google is also working on developing better Flutter plugins that will make the use of Firebase easier.

Updates for Mobile

After a collaboration with Microsoft, Flutter 3.0 will now provide programming support for foldable mobile devices. Also, there are new features and widgets which will allow developers to build eye-catching and dynamic interfaces for foldable devices.

For iOS devices–

On iOS devices, Flutter now supports variable refresh rates along with promotion displays. Previously the refresh rates are only limited to 60hz, while now it can reach up to 120hz for a smooth experience during fast animations like scrolling.

Flutter3 has also simplified the iOS app delivery. For instance, When you are distributing the app to TestFlight or the AppStore by using the XCode archive and app bundle, there are some of the methods that can be used:

• – -export-method development
• – -export-method ad-hoc
• – -export-method enterprise

After the building of the bundle is finished it can be submitted to the Apple using Apple transport macOS program or the xcrun tool that is on the command line. After the uploading of this process, the app is available for the release to App Store or TestFlight.

Gradle version updation-

The latest versions of Gradle and Android Gradle plugins are used in the files that are generated by using the Flutter 3 version. The projects that are made earlier need to be manually upgraded from 7.4 to 7.1.2 by using the latest Android Gradle plugin.

Interpreting iOS 9 and 10 and 32-bit devices-

As already announced in Feb 2022, Flutter’s support for 32-bit iOS devices and iOS versions 9 and 10 will be terminated. Flutter 3 is the last stable version that supports iphone5, iphone4s, iphone5c, and the 2nd to 4th generation iPad devices.

Updates for Web

Decoding of image

With the newest updates in Flutter 3, the image decoder API is automatically detected and can be used in the browser that supports it. Most chromium-based browsers have the support of this API. The speed of picture decoding is doubled up with the support of the browser’s built-in image codecs.

API Lifecycles

The new version of API lifecycles gives the flexibility to handle the bootstrap process of your Flutter app and also helps Lighthouse to analyze your app’s performance.

This applies to many different scenarios listed below-

• Loading indicators
• Splash screen
• A simple interactive HTML landing page that is exhibited before the Flutter app.

Tooling Updates

Updation of Lint Package

Apps that are generated by Flutter 3 can automatically enable the v2.0 set of lints. So, the apps and packages that are made earlier stimulate to migration to v2.0 for the latest updates.

 Casual Games Toolkit

Previously Flutter was all about apps and their functionality but now it has expanded its horizon even more.

With Flutter 3.0, Google has introduced the casual games toolkit with a suite of templates, guidelines, and tutorials that will allow mobile app developers to create and launch games from scratch.

Dart 2.17

Flutter 3 also comes up with a new update for the Dart SDK with the language version 2.17.

Dart 2.17 has several new features which allow developers to extend enums, deploy and test custom-written classes, and override as default functions.

More exciting Updates

By using the theme extensions feature you can now add anything to the material library’s ThemeData rather than extending and re-implementing its copy with, lerp, and other functions.

Personalized Ads

It is necessary for the publishers to handle Apple’s App Tracking Transparency regulations (ATT) to request consent for personalized ads. For all these needs Google offers the User Messaging Platform (UMP) SDK, which replaces the previous source Consent SDK.
