What’s new in Flutter 2.8

Flutter aims to change how apps are built. It unites mobile, web, desktop, and embedded development into a single toolkit: letting developers focus first on what they want to build, rather than which platforms they want to target; offering a high-performance, high-productivity framework that shortens the inner loop for developers; and enabling one codebase to target multiple platforms and form factors.

New features and improvements: faster and more productive

One of the major areas of focus for this release is mobile performance. Ideally great performance would come for free, but in practice any complex app needs optimization to make sure it uses the underlying hardware and libraries well. That includes startup performance, which can be constrained by network bandwidth or other initialization costs; memory usage, particularly on memory-constrained devices; and graphics rendering. We’ve been using some of our experiences with large Google apps like Google Pay to invest both in making Flutter itself more performant, and in giving you better tooling to guide profiling and optimization of your own app. Your apps should start faster and use less memory just by upgrading to Flutter 2.8.

The latest update makes it easier than ever to connect apps to back-end services, such as Firebase and Google Cloud. It adds production-quality support for Google Ads and major upgrades to the camera and embedded web plugins. The release also includes Dart 2.15, which adds major improvements to concurrency, new language features like constructor tearoffs and enhanced enumerations, and optimizations that deliver a 10% reduction in memory utilization.

With the new developer productivity enhancements to Flutter, an app can support sign-in to multiple authentication services with just a single drop-in widget.

Another big theme of investment in this release that you’ll see us carry forward into future releases is further improving developer productivity. With features like stateful hot reload, we’ve always focused on creating a tight inner loop for developers. We’re now starting to explore some higher-level abstractions that make it easier for developers to get running faster. For example, in this release we’re adding a sign-in widget that uses Firebase to handle authentication. With this widget, you don’t have to worry about all the edge cases of sign-in, such as two-factor authentication or reset password user flows, nor about the complexities of supporting Google, Apple, Twitter, or Facebook as an auth provider. Features like this, building on the core foundations of Flutter, have the potential to transform how developers build apps, combining the development speed of low-code solutions with the flexibility and power of a full UI framework.

Both Flutter 2.8 and Dart 2.15 are available now, and should be an easy upgrade for existing apps running the previous version. For greater detail, we have a technical blog post covering the enhancements in each of Dart and Flutter.

Casual game development with Flame

For most developers, Flutter is an app framework. But there’s also a growing ecosystem around casual game development, taking advantage of the hardware-accelerated graphics support provided by Flutter.

Today, we are thrilled to celebrate the 1.0 release of Flame, a modular 2D game engine built on top of Flutter. Flame provides what you need to build games quickly: as well as a game loop, it also includes core primitives such as a component system, animated sprites and images, collision detection, a world camera, an effects system, and gesture and input support.

Flame is modular and can also be extended with packages that offer integrations to other libraries, for instance Rive (for animations), audioplayers (for music and sound effects), Forge2D (a Box2D-style physics engine), Tiled (tile maps editor), Fire Atlas (a sprite sheet and animation editor). Together, Flame and the broader ecosystem offer a strong set of services for a casual or 2D game developer.

Flame is created by Blue Fire, a group of contributors focusing on creating open source packages and plugins for Flutter and Dart. We’re delighted to partner with them and encourage you to check out Flame if you’re interested in game development.

Flutter’s continued momentum

We’re amazed to see how fast Flutter continues to grow, with a flourishing ecosystem of apps and tools that build on top of the core framework. At this year’s Google I/O event, we noted that there were already over 200,000 apps built with Flutter in the Play Store. In just over six months since that event, the number of Flutter apps has nearly doubled, with more than 375,000 Flutter apps now in the Play Store.

Flutter supports Android, iOS, iPadOS, web, Windows, macOS and Linux: so you don’t have to rewrite your app just to target a different device or form factor.

Flutter isn’t just used on Android, of course. According to independent mobile analyst firm AppAnnie, apps using Flutter on iOS include top brands and apps including BMW, eBay, WeChat, SHEIN, Philips Hue, Norton, trip.com and Greggs. On the web, Flutter is finding a home for app experiences, benefitting design tools like FlutterFlow and Rive. On desktop, the Ubuntu engineering team continues to build a variety of new experiences with Flutter, including a new installer and firmware updater. Even games like PUBG are finding that Flutter is a great fit for UI screens.

Ecosystems take a long time to build, but Flutter is now the most popular multi-platform toolkit, as measured independently by Statista, JetBrains, SlashData, and Stack Overflow. We don’t take that for granted, but the growth of Flutter’s popularity leads to an ever broader ecosystem of packages and tools that support it.
