Flutter 3.3 Released: What’s New Update in Flutter

A few months ago Flutter declared a stable release and we are proud to announce Flutter 3.3 has bought some exciting and stable releases for Windows, macOS, and Linux.

Flutter 3 is ready to be created on all desktop scenes. We’re invigorated and can barely sit still to share what’s new in Flutter, its support for macOS and Linux, notable performance upgrades for web and mobile, and the addition of Support from Apple Silicon.

Introduction

Flutter improves frameworks, widgets, library packages, speed optimization, and others to make our development process powerful, smooth, and productive.

Flutter 3 came across to develop a single codebase for 6 platforms. 

It helps developers by providing them with a free environment to put their new ideas and excellent user experiences with just one code base.

Flutter became a multi-step user interface tool for creating natively compiled applications in just a few years. 

The best thing about Flutter is its open source and anyone can publish their ideas, create packages, compose different hardware, compile native code, and much more things.

Stability for macOS and Linux

Android, iOS, web, and windows have been stable for some time and now finally flutter came up with macOS and Linux stability.

So this one is the main achievement in the journey of Flutter up to now supporting all six platforms.

Material 3

Flutter 3.3 now supports Material design 3 and an In-house concept by Google for the following Material. 

Flutter migrated with FloatingActionButton, ThemeData, NavigationBar, Dialog, Splash effect, Navigation Rail, Card widget, and much more.

Material 3 supports and includes  elements like:

• Dynamic Colors
• The visual effect in android 12
• Typography upgrades
• New Buttons and App menu
• others

Firebase with Flutter

Flutter has declared complete compatibility with Firebase, so flutter is now turning into a fully supported key path in order to reflect reality and consistent growth for firebase plugins.

About 63% of flutter developers preferred to use Firebase in their applications, so google is now working on creating widgets to make applications smoother to use firebase in their application.

Also, Firebase has improved Crashlytics to make the app crash free and now users can track their errors and fix the bugs by using Firebase Crashlytics plugins.

Updates in Mobile

• Flutter 3.3 supports a refresh rate of 120hz on IOS devices like iPhone 13 Pro and iPad pro, earlier it supported up to 60z.

• Support with foldable mobile devices by collaborating with Microsoft.

• In Flutter 3, now user can directly create an IPA file with the command to launch an application on IOS devices

Games Toolkit

• Flutter is not just a framework but also a casual game development toolkit.

• The flutter development community provides graphic support to develop open-source game engines like Flame.

• The casual game toolkit provides a starter kit of templates for cloud services and ads.

Impeller

• Flutter Impeller is a meta framework to precompile a smaller and simpler set of shaders while the engine builds so while running the app it won’t compile.

• Not all features are implemented yet, but in the meantime, flutter shares its progress.

• To use impeller in the Flutter app, you can add –enable-impeller while flutter run or set FLTEnableImpeller flag inside Info.plist file to true.

Image decoding

• Flutter’s new lifecycle API makes the bootstrap process very smooth and flexible for Flutter web applications.

• Flutter improves imagecoder API and flutters updates the image decoding API to 2x faster in order to remove the jank that was caused by the image.

Android Inline ads

• For the google_mobile_ads plugin, flutter has improved user critical instruction such as transitions between pages while scrolling.
• Flutter now refers to hosting native Android views in your Flutter app with Platform Views asynchronously. It means the flutter raster thread will be directly rendered using OpenGL texture.

Breaking Changes

• With Flutter’s latest release, there are some breaking changes
• Deprecated API removed after v2.10
• Page transitions replaced by ZoomPageTransitionsBuilder
• Migrate useDeleteButtonTooltip to deleteButtonTooltipMessage of Chips
• Here is a migration guide if you are using any of these APIs.

Summary

Well, this is one of the highlights from Flutter 3 to Flutter 3.3 with six different platforms: stability, improvements, performance, and migrations. And some new exciting features like the game toolkit and looking forward to knowing more about the in-house concepts in material 3 by google, We hope you like this article.
