This latest version supports macOS with the universal binary system and runs on both Intel-based Mac and Apple silicon platforms. Developers prefer to use this version for its cross-platform benefits. Flutter 3.0 can change the whole development experience and offers several benefits. Increased developers’ productivity and faster time to market are the best among them.

Casual Game Toolkits

Different famous games ( for instance- PUBG MOBILE) counted on Flutter for non-game UIs. A fun pinball game powered by Flutter’s web support and Firebase also depended on Flutter.

Simplified ios App Release 

New options to the Flutter build ipa command has simplified the ios app release. You can run flutter build ipa to build an Xcode archive (.xcarchive file) and an app bundle (.ipa file) after you are ready to distribute to TestFlight or the App Store. Optional adding options for —-export-method ad-hoc, —-export-method development, or —-export-method enterprise is also there. 

After creating the app bundle, use Apple Transport or macOS app to upload it on Apple. Flutter developers use the command line using xcrun altool (run man altool for App Store Connect API key authentication instructions as well. Afters completing these processes, your ios app will be available for release to the App store or TestFlight. You don’t need running Xcode after running the Xcode project settings.

Compatible with Material 3 Designs 

The popular in-house design of Google, Material 3, is compatible with Flutter 3.0. This feature enables developers to create interface designs easily. This Flutter version comes with engaging visual effects, better color systems, and typography that can provide the best digital solutions.

Supports ios Refresh Rates

This recent release of Flutter gives required support to refresh rates on the ios devices with the Promotion displays. You can enjoy the refresh rate of 120 Hz on iPad pros or iPhones. The earlier refresh rate was 60 Hz. So, you can say, this rate becomes doubled, and it provides a better user experience while using faster animations.

Top-Grade Firebase Integration

Firebase denotes a BaaS ( Backend-as-a-service) that provides the hosted backend solutions. Using firebase in the apps is nothing new.

In the previous flutter versions, the upgradation of existing extensions and apps was mandatory. But, lint v.2 packages come with automatic updates in this version. It enables plugins and apps that don’t use this package yet to migrate to the guide.

Performance improvements in the opacity animations must need mention. In the conditions when opacity widgets comes with a single rendering primitive the savelayer method omits the Opacity. The rasterization time gets improved by the order of magnitude. More scenerios in the future will get this optimization. 

Quicker frame-building time gets possible in this latest version. Thanks to the Dart VM background garbage collection threads.

Flutter 3.0 also introduced a new mechanism that can estimate the rendering capacity based on the draw operations. Doing this as the raster image admissions policy reduces memory usage without hampering performance. 

CodePaleLight, an open source contributor fixes bug in the frame scheduling that allows throwing a few animation frame drop on the ios platform. 

Image Decoding

The presence of an asynchronous decoding feature for the main thread is a feature of the updated API. Flutter 3.0 feature present in the built-in image codecs in browsers offers speedy development and saves the main thread from junk build-up.
