How is Flutter 3 Better than flutter 2?

Flutter has emerged as the undisputed and most popular cross-platform UI toolkit for developing natively compiled applications. Today Flutter 3 is a brand-new version that 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.

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, building packages that support the core framework, writing material and tutorials, and a variety of other methods.

Flutter 2 in comparison to Flutter 3

Flutter 3 now supports macOS for Universal Binaries, allowing Flutter apps to run natively on Apple Silicon chips and Intel processors. For the Linux release, Google collaborated with Canonical to deliver a highly integrated cream of the crop option for app development. Let’s look at what’s new in Flutter 3 to learn about all of the important features of Flutter’s stable release.

Menu Cascading and MacOS System Menu Bar Support

  • Fresh inputs for platform-specific integration and interactive models for compilation to build support, accessibility, and internationalization are among the new Flutter 3 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.
  • Growing businesses should always consider to hire flutter app developer who benefits from a suite of Flutter services while not compromising the quality and productivity of their Flutter apps.

Firebase Flutter

App publishers require a comprehensive set of tools to help you operate, build, and release your Flutter apps. Data storage, authentication, device testing, and cloud functions are examples of such services. Flutter supports a number of third-party integrations, which is s 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.

  • You can now track real-time fatal errors with the Flutter Crashlytics plugin, which offers the same features as Firebase’s well-known real-time crash reporting service.
  • The features include critical alerting metrics such as crash-free users, which help you keep track of your app’s stability.
  • The Crashlytics pipeline, which has been upgraded to improve the clustering of Flutter crashes, now makes it simple to triage, prioritize, and fix issues.

You Support This Material

The transition to Material Design 3, a Google in-house design language, is one of the top highlights of what is new in the 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.

Updates for Mobile

  • What has changed in Flutter 3? New widgets and features enable you to create visually appealing experiences on foldable devices. The new Flutter release, on the other hand, includes foldable mobile devices. This function was created in collaboration with Microsoft.
  • 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.

Extensions for the theme

Using Theme extensions, you can now add anything to the material library’s ThemeData. You can use Themeextensions instead of extending ThemeData and reimplementing copyright and other methods. You can also provide ThemeExtensions as a package developer. Now you should hire Flutter app developers. Because working with a leading Flutter app development company is an excellent way to develop faster and more efficient applications.


Flutter 3 complies with the publisher’s requirements for creating personalized ads and Apple’s App Tracking Transparency requirements. Google offers a User Messaging Platform SDK, which replaces the previous open-source Consent SDK.

Decoding of Images

Flutter web can now automatically detect and use the image coder API in the browser. This updated API decodes images asynchronously off the core thread using the browser’s built-in image codecs. This increases the speed of pictures by 2x without blocking the mainline and removes all jank previously caused by images.

Website Updates

  • The most recent Flutter upgrade includes new APIs for decoding images off the main thread asynchronously. This is accomplished using the browser’s built-in image codecs.
  • You will 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.
  • 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.

The Flutter 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, ad credits, and 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.
  • Many games built with Flutter have been released on the market. Game developers can also take a tour of the flame game engine to learn more about how Flutter works in games.

Performance Enhancements in Flutter 3

  • 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.
  • The Flutter features include 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.

Bottom Line

Undeniably, the community deserves all praise for doing such amazing work to help Flutter achieve the status of prestige and innovation to maintain its caliber of assisting businesses of all shapes and sizes worldwide. Finally, you have had a comprehensive experience reading about what is new in Flutter 3 instead of Flutter 2. Flutter’s future appears bright and promising for creating delightful experiences in the app ecosystem.
