If you are starting to develop with Flutter and have ever asked the question “what’s so cool with it?” Then this blog is for you.

Google supports the open-source Flutter toolkit for creating stunning, quick user interfaces on any platform. Whether you're writing for the web, mobile, or desktop, it enables you to write your UI with a single common codebase. Additionally, it is designed to bypass the conventional edit, build, launch, and debug lifecycle. What platform you are aiming for doesn't matter with Flutter 3.0. Instead, your originality and original ideas are what stand out.

So let us take a look at What's New in Flutter?

All desktop phases are operational and ready for construction using Flutter 3.0.

Assistance for macOS and Linux, notable speed enhancements, upgrades to mobile and web platforms, and much more are all features of Flutter.

The latest version 3.0 of Desktop Flutter offers several improvements for Windows as well as compatibility for Linux and macOS that has reached a stable state. Here are some more examples:

  • Support for the macOS system menu bar and cascading menus
  • The PlatformMenuBar plugin, which permits the insertion of platform-only menus and gives you command over what appears in the macOS software menus, allows you to now construct system menu bars on macOS.
  • Complete international text input compatibility across all desktop platforms
  • All three desktop platforms offer full services for international text input, including IMEs for languages like Chinese, Japanese, and Korean as well as third-party input tools like Sogou and Google Japanese Input.
  • Compatibility with every desktop platform
  • Screen readers, adaptive navigation, and inverted colors are just a few of the accessibility features that Flutter for Windows, macOS, and Linux supports. 
  • MacOS includes universal binaries by design
  • Flutter desktop apps for macOS are now created as universal binaries with native support for both older Intel-based Macs and the newest Apple Silicon devices as of Flutter 3.
  • Windows 7 and 8 being phased out for development
  • We are increasing the suggested Windows version for research with this release to Windows 10. Older versions (Windows 7, Windows 8, and Windows 8.1) are not blocked from development, but Microsoft no longer supports them, and we only offer restricted testing on these releases. Although we will still make a "best effort" to maintain previous versions, we strongly advise you to upgrade.

    For Mobile.

    The new Flutter version is heavily related to the provision of mobile application development services. Now, it's simple for Flutter developers to give mobile users a more alluring and fluid experience. The upgrades for mobile are as follows:
  • Foldable mobile assistance.
    The latest version of Flutter makes it easier for developers to create engaging experiences on foldable devices thanks to new integrated capabilities and widgets. Thanks to Microsoft's facilitation of cooperation, it was made possible. In order to represent the states and boundaries of device aspects, MediaQuery includes a large number of Display Features. The default dialogues and pop-ups of the framework have been merged with the DisplayFeatureSubScreen widget as well, enabling Flutter reactive and aware of these elements.

  • Easy iOS Releases & Support for Refresh Rate.
    The addition of new options to the IPA command created by Flutter has simplified the publishing of iOS apps. Additionally, Flutter 3.0 will enable Promotion displays with varying refresh rates on iOS devices like the iPad Pro and iPhone 13 Pro. The refresh rate of iPhone devices, which was formerly 60 Hz, is now 120 Hz. Giving users a better experience when there are animations is beneficial.


  • iOS 32-bit sunset/iOS 9/iOS 10.
    Well with Google Flutter 2.10 stable release in February 2022, it has already been made clear that Flutter will no longer provide compatibility for 32-bit iOS devices and iOS 9 and 10 versions. The iPhone 4S, iPhone 5 and 5C, as well as the 2nd, 3rd, and 4th generation iPad devices, will all be significantly impacted by this radical change. The most recent stable version of Flutter, version 3.0, will support all iOS devices and various versions.
  • A Gradle Version Update.
    It should be mentioned that the most recent versions of Gradle and the Android Gradle Plugins were used to create each file during the Flutter app development services. Developers must manually install versions 7.4 of Gradle and 7.1.2 of the Android Gradle Plugins if they are working on any active projects.


     Web Applications.
    The upgrades listed below can be used for web app development by your selected Flutter app development firm. The following is included in these updates.
  • Image decoding.
    In browsers that support it, Flutter web now automatically identifies and utilizes the ImageDecoder API. The majority of Chromium-based browsers (including Chrome, Edge, Opera, Samsung Browser, and others) as of right now have this API.
  • Using the built-in image codecs of the browser, the new API decodes images concurrently off the main thread. This eliminates any junk that was previously brought on by images and accelerates image decoding by a factor of 2. It also never interrupts the main thread.
  • Web application lifecycles.
    The updated lifecycle API for Flutter web apps allows you the freedom to manage your Flutter app's bootstrap procedure from the HTML page that hosts it, and it works with Lighthouse to assess your app's performance.
  •  Toolkit for Casual Games.
    Most developers only think about Flutter as an app framework, but it has a significant population for casual game development that takes advantage of its capability for hardware-accelerated graphics. Flame is one of the open-source game engines offered by Flutter. To make game development simpler, the brand-new Flutter Casual Games Toolkit also includes best practices, tutorials, source code, and a prototype pinball game based on the Flutter theme.


  • Advances in Performance.
    Android device users now have access to partial repaint thanks to open-source contributor knop. Additionally, for certain of the fundamental case scenarios, the efficiency of opacity transitions has been enhanced. A technique for calculating the difficulty of rendering graphics based on the cost of rendering operations has also been added in Flutter 3.0.
  • It also functions as a way to reduce memory usage without impairing the functionality of the Flutter app.

    The Flutter ecosystem has also received the following updates:
  • Substance 3
    The latest iteration of Material Design, Material Design 3, is supported by Flutter 3. Flutter 3 offers Material 3 opt-in support, which includes Material You will find in Android 12 new visual effects including a contact ripple design and a stretched overscroll effect, as well as features like dynamic colour, an improved color system, and typography. Try out the fresh Take Your Flutter App From Dull to Attractive codelab's Material 3 features. For information on how to prefer to such new capabilities and which components support Material 3, consult the API docs.
  • Theme augmentations.
    With such a phenomenon called Theme extensions, Flutter now makes it possible to add anything to the ThemeData of the Material library. You can specify ThemeData.extensions rather than enhancing (in the Dart sense) ThemeData and re-implementing its copy With, lerp, and other methods. You can also offer ThemeExtension as a package developer.


  • Ads.
    We are aware that it is crucial for publishers to obtain permission for tailored ads and to comply with Apple's App Tracking Transparency (ATT) rules.

Google provides users Communication Platform (UMP) SDK, which takes the place of the earlier open source Consent SDK, to meet these criteria. To enable publishers to gain user consent, we are include support for the UMP SDK in the forthcoming launch of GMA SDK for Flutter.

Flutter 3.0 is quite a nifty framework to say the least. While some of its features are not unique in the context of cross-platform frameworks, they all come together to provide a very modern and productive development experience that iOS and Android developers alike can appreciate.
