Created by Google, Flutter is a software development kit for creating natively compiled apps for mobile, web, and desktop from a single code base.


“Flutter transforms the app development process. Build, test, and deploy beautiful mobile, web, desktop, and embedded apps from a single code base. Flutter code is compiled into ARM or Intel machine code, as well as JavaScript, for fast performance on any device.


Flutter 3.3 and the news that this technology brings


Flutter released its most recent version 3.3 and it detailed on its website everything new that comes with it and aspects added since Flutter 3.0.


  • The Navigation and Routing overview page has been rewritten with more guidance on using Navigator and Router together, named routes, and using a routing package.
  • The URL Strategies page has also been updated to reflect a more optimized API.
  • For apps not published on the Microsoft Store, you can now configure the app's executable and product versions in the pubspec. For more information, see Build and launch a Windows desktop app.
  • If you are developing software for iOS 16 and higher, you must enable Developer mode. The macOS setup page is updated with this information.
  • As described in the 3.3 release notes, you should catch all errors and exceptions in your application by setting the PlatformDispatcher.onError callback, rather than using a custom zone. The Error Handling in Flutter page has been updated with this tip.


Benefits of using Flutter for the construction and development of web pages and applications

One code base: This framework allows you to develop apps for both Android and iOS, and because it renders everything itself, it allows the developer to run everything within a single code base, saving a significant amount of time.


A beautiful interface in no time: In Flutter, the UI is built with widgets, these are little UI building blocks and use a technique called Composition. The whole process of creating the interface is similar to using React components.


Pixel rendering: Because Flutter manages every pixel on the app's screen, the widgets you create will look the same on all mobile devices, including older models, eliminating device support issues and allowing you to create user interfaces. The user looks exactly the same on both Android and iOS.


Rapid Development: One of the features of Flutter that has really made it shine among its users, is the hot reload feature provides the ability to make changes on the fly, allowing you to see them immediately during development.


Cross-platform app development: As already mentioned, the Flutter SDK is a cross-platform tool that allows us to develop for desktop, mobile, and the web using a single code base.
