Quick Summary

Flutter 3 is now available and ready for use on all desktop platforms! We are very excited and can’t wait to share what’s new in Flutter, including its support for macOS and Linux, remarkable performance improvements for web and mobile, and the addition of Apple Silicon support. In the end, there are some extra tips for updating your Flutter version. 

Only three months have passed since Flutter announced Windows support, and here we are, almost in the middle of May, with the latest Flutter update. This brand-new version is compatible with macOS and Linux, and it supports Apple Silicon. The Flutter 2 to Flutter 3 version upgrade bridges the gap between a mobile-centric and a multi-platform framework.

Flutter has emerged as the undisputed and most popular cross-platform UI toolkit for developing natively compiled applications. The best thing about Flutter is that it is more than just a Google product, and its success is accessible to all. Anyone can harness the power of this open-source platform by contributing code, developing packages that support the core framework, writing material and tutorials, and so on.

What’s New in Flutter 3: Latest Features

1. Menu Cascading and Support for the MacOS System Menu Bar

Fresh inputs for platform-specific integration, interactive models for compilation to build support, accessibility, and internationalisation are among the new Flutter 3.0 features.

The update’s goal is to provide flexibility in how the operating system is used and to share optimal UI and logic as needed. Beyond rendering pixels, the latest Flutter features cater to platform support.

2. Material You Support

The transition to Material Design 3, a Google in-house design language, is one of the top highlights of our what’s new in Flutter 3 discussion. The Flutter team has provided a versatile cross-platform design system to help you turn your Flutter app into a stunning interactive product.

3. Flutter Firebase

To help you operate, build, and release your Flutter apps, app publishers require a comprehensive set of tools. Data storage, authentication, device testing, and cloud functions are examples of such services. Flutter supports a number of third-party integrations, including Firebase, AWS Amplify, Sentry, and AppWrite. Google Firebase is a back-end platform for developing mobile and web applications.

The Flutter team has announced Flutter Firebase integration, which allows for a fully supported core part of the Firebase offering.

4. Flutter’s Games Toolkit

This time, the Flutter team has focused on casual gamers, releasing an easy-to-use casual games tool kit. It provides a starter kit of templates and ad credits, as well as cloud services. Flutter engineers created a fun pinball game powered by Firebase and Flutter’s web support, demonstrating the versatility of the new Flutter 3 update. You can create games on Flutter by using the Games doc page.

5. Mobile Updates

• Foldable support for phones

The new Flutter release, on the other hand, includes foldable mobile devices. New widgets and features enable you to create visually appealing experiences on foldable devices. This function was created in collaboration with Microsoft.

• Variable refresh rate support for IOS

On iOS devices such as the iPad Pro and iPhone 13 Pro, the new Flutter version supports variable refresh rates and ProMotion displays. The rendering capability is now available at refresh rates of up to 120 Hz, up from 60 Hz previously. While watching fast animations, the user can have a smoother scrolling experience.

6. Web Updates

• Image Decoding

The most recent Flutter 3.0 release includes new APIs for asynchronously decoding images off the main thread. This is accomplished using the browser’s built-in image codecs. You’ll be glad to know that this feature speeds up image decoding by 2x, ensuring that the main thread is never blocked and clearing the junk that has accumulated in the past.

• Web App Lifecycles

The new web app lifecycle API for Flutter apps lets you control the process of bootstrapping your app. You can now use desktop support for your app.

• Flutter 3 Performance Improvements

The Flutter engineering team has taken Flutter performance improvement to the next level by benchmarking to assess the benefits of optimization. Most importantly, the opacity animation performance for simple case scenarios has been improved. For example, when an Opacity widget is composed of a single rendering primitive, the save layer method is omitted and Opacity is usually invoked.

The Flutter 3 release includes a mechanism for predicting and estimating the rendering picture complexity based on the cost of drawing operations. This is used as a method to reduce memory usage while maintaining Flutter app performance.

More Exciting Features: What’s New in Flutter 3?

1. Theme Extensions

Using Theme extensions, you can now add anything to the material library’s ThemeData. You can use ThemeData.extensions instead of extending ThemeData and reimplementing copyright, lerp, and other methods. It is an amazing flutter animation library that you can easily add to your flutter project. You can also provide ThemeExtensions as a package developer.

2. Ads

Flutter 3.0 complies with the publisher’s requirements for creating personalized ads as well as Apple’s App Tracking Transparency (ATTT) requirements. Google offers a User Messaging Platform (UMP) SDK, which replaces the previous open-source Consent SDK.
