Flutter 3 is here! And it’s packed with several new features and enhancements for you to enjoy. Let’s take a quick look at what has changed, what is new, and how it will help us build beautiful apps faster than ever.

Flutter is a great platform for building multi-platform apps. It helps you keep your code clean and manageable, offering features like hot reload, a fast rendering engine, stateful hot reload, and polish with a rich ecosystem of libraries. In addition, use Flutter to build apps from scratch or incrementally add new features over time.

This post will cover what’s new in Flutter 3, so you can start building beautiful apps today!

But first, let’s look at some of the accomplishments of Flutter 2.0

150 billion Flutter-based app launches per month

Flutter is a platform for building native apps, meaning that you can write your app once and deploy it to multiple platforms like iOS and Android. With a single codebase, Flutter makes it possible to build beautiful applications with high performance and a native look and feel (or reactivity) for both mobile and desktop.

Flutter apps can run both on iOS and Android devices, as well as on the web, through an in-browser rendering engine. It means that if you’re developing a mobile app with Flutter, there’s no need for separate teams to ensure its compatibility across devices—one team can build everything from scratch with one codebase for each platform (iPhones or Androids).

Top brands have invested in Flutter

Top brands have invested in Flutter because of its speed, ease of use and ability to produce high-quality apps. As the parent company of FanDuel, Sky Betting & Gaming, Sportsbet, Sisal, PokerStars, Paddy Power, Betfair, Adjarabet, TVG, and Junglee Games, Flutter owns many international brands and operations.

What Are Popular Apps Made with Flutter?

Flutter is a powerful platform for building some of the world’s most popular apps. Here are just a few examples:

Google Pay

Google Pay, one of the most popular apps, uses Flutter as its core technology. Using Flutter, the engineers could rebuild it into a lighter app and maintain all the features and functions. And they did all these updates and edits while millions of people were using Google Pay. They managed a lot of time, energy, and money by using Flutter. 

Xianyu by Alibaba

Xianyu by Alibaba is an app that helps users find local businesses, restaurants and hotels. It’s one of the most popular apps in China built using Flutter. The app currently has over 200 million instals on Android and iOS.

Google Stadia

Google Stadia is a gaming cloud platform that allows users to play their favourite games from any device. It was built using Flutter and currently has millions of instals on Android and iOS.

Google Ads

Google Ads is a mobile app that helps advertisers manage their campaigns. Google chose Flutter to avoid maintaining two separate codebases—one for iOS and one for Android.

What is Flutter 3, and What is new with Flutter 3.0?

Flutter 3.0 is the latest version of Google’s popular cross-platform mobile development toolkit. It features many new updates, including improved support for Android Q and iOS 13 Beta, a new Flutter Inspector 2.0 with improved performance and usability, a new way to sign APKs without needing a Keystore file on your computer, streamlined project navigation in VS Code and IntelliJ IDEA, and much more.

Ready for production on all desktop platforms

You’ll be able to use Flutter for production-quality apps on all desktop platforms, including Windows, Linux and macOS. No more experimental mode. In the area of programming languages, Flutter 3.0 is highly compatible with JavaScript—making web development more efficient.

Cascading menus and support for the macOS system menu bar

Cascading menus are a new feature that allows you to create multi-level navigation in your Flutter app. The macOS system menu bar is a separate menu bar for macOS apps, located at the top of the screen and contained within the standard macOS title bar. The current implementation supports adding items to both types of menus:

  • Cascading menus are represented using an abstract class called Cascade. It contains all the APIs required to work with cascading menus, including animations, state management, and more.
  • Apple’s system menu is represented by a subclass of AppMenuItem named MenuItem that has been added through import support in Flutter 3 under the dart:ui package name.

Full support for international text input on all desktop platforms

With the new version, Flutter now supports international text input across all desktop platforms. You can now write in any language, including Chinese or Japanese, on macOS and Windows. Also, you can copy and paste text from other apps into your Flutter app without worrying about encoding issues.

Firebase Integration

Firebase is a mobile platform that helps developers build better apps, grow their user base and earn more money. In the latest report from Slashdata, 62% of Flutter developers named Firebase their primary backend platform.

Flutter 3.0 contains Firebase support, which includes the following features:

– You can add a Firebase project to your Flutter app by running flutter create -i firebase . It generates a starter project that includes all of the Firebase dependencies and integrations you need to use many of its APIs.

– You can use Firebase Authentication, Cloud Firestore, Cloud Functions for Firebase, and other services from your Flutter app.

Flutter casual games toolkit

The Flutter casual games toolkit is a library of reusable Flutter components for building casual games. It is open source and available on GitHub, so developers can use it to develop their own casual games for the Android platform today.

Flutter has also recently added support for iOS devices (at launch) and macOS, tvOS and watchOS in general (not explicitly targeting gaming).

Web app lifecycle

The new Flutter web app lifecycle differs from the Android and iOS versions. The most crucial difference is that it does not have an Activity or ViewController class. Instead, Flutter uses its own framework to handle the life cycle of web applications.

It means that you do not need to worry about managing the state of your application because Flutter handles it for you. For example, if a user closes the tab or window where they are using your web app and then opens a new one, the old one will be closed automatically, and the new version will open instead.

iOS variable refresh rate support

The iOS 13 operating system will enable developers to provide variable refresh rate support for their apps. Variable refresh rate support is an operating system feature that allows users to set their display’s refresh rate between 60Hz, 120Hz or 240Hz. The higher this number, the smoother the animation can appear.

Image decoding

The Flutter team has added image decoding support for JPEG, PNG, GIF and WEBP images. Also new is support for the WebP format, which allows you to deliver smaller files than are available with JPEG. Animated GIFs are also supported. Image loading from a network URL or filesystem path is also possible as well!

Flutter is a great platform for building multi-platform apps.

Flutter is an excellent platform for building multi-platform apps, and it’s built on top of Dart. Dart is an open-source programming language used to build web, server, mobile, and other apps. It’s easy to learn and can be used by anyone with minimal programming experience.

Flutter is a cross-platform framework; you can use the same codebase for iOS and Android apps. That’s right: no more separate teams working on different platforms!

Flutter is an app development company that allows designers to create beautiful user experiences using their favourite design tools like Sketch or Photoshop; developers get the resulting assets from Flutter Studio without having to write any code! The best part? You don’t have to learn any new languages or frameworks—you start building your app.
