The app development world is abuzz with the latest announcements from Flutter and Dart. With Flutter 3.24 and Dart 3.5, developers are set to experience a host of innovations and enhancements that promise to elevate app building to new heights. Whether you're an app developer, a member of the Flutter community, or a tech enthusiast, these updates are packed with features designed to improve your workflow and the end-user experience.
Key Changes at a Glance
- Impeller API: New low-level graphics API unlocking high-performance and immersive visual experiences.
- iOS Enhancements: New Cupertino widgets and early support for Swift Package Manager.
- macOS Improvements: Better integration with platform view and webview support.
- Language Interoperability: Simplified use of native APIs and libraries across C, Java, Kotlin, Obj-C, and Swift.
- Enhanced Pub.dev: Improved package management and repository features.
Unleashing New Possibilities with Flutter 3.24
The Power of Impeller and Flutter GPU
Regarding Impeller, the new render engine, we continue to see how its migration is almost complete, now nearly becoming the default on Android, as it already is on iOS. This change brings significant performance improvements on mobile devices, given that the Flutter team literally built their own render engine to solve problems that had become very difficult to address using the SKIA version. This is crucial as the team continues to raise the bar in terms of the quality and speed with which Flutter applications are made, ultimately benefiting end users.
On the Flutter side, we're seeing how Impeller is beginning to unlock new possibilities for app development. Flutter 3.24 introduces the new Flutter GPU API—a low-level graphics API that enables stunning, high-performance, and immersive experienceses.
While Flutter GPU requires Impeller, the goal is to eventually support it across all platforms. To dive deeper into these new changes, you can check out this article about Getting started with Flutter GPU.
In my opinion, the key takeaway here is that Flutter isn’t just focused on being multi-platform but is also committed to delivering top-notch visual experiences. Flutter's goal is to take things a step further when building applications—not just sticking to a standard look & feel, but providing innovative user experiences that captivate users with something fresh and surprising.
Enhancements for iOS and macOS
When considering the improvements within the Apple ecosystem (iOS and macOS), it’s clear that this new version introduces many changes focused specifically on these platforms. One of the main concerns when developing apps is achieving the same level of look and feel as the native target platform. While this is something native technologies provide out of the box, Flutter continues to invest significant efforts in delivering that same experience. That’s why the Cupertino library remains a solid option for matching the iOS aesthetic.
For macOS, there’s now better integration with platform views and WebView support, ensuring a smoother and more seamless experience. iOS developers will appreciate the new Cupertino widgets, which make it easier to achieve the desired look and feel. Moreover, Flutter has introduced early support for Swift Package Manager, a highly anticipated change that is expected to boost its adoption in the iOS development ecosystem.
In conclusion, the iOS ecosystem is evolving, and Flutter is keeping pace with these changes. In the near to mid-term, we’ll see current packages migrating to Swift Package Manager, allowing developers to adopt the more modern Swift language while minimizing reliance on Objective-C. This makes developing apps in Flutter with a focus on iOS a great choice—even without considering the added advantage of cross-platform code reuse. Whether through new libraries utilizing Swift Package Manager, platform views accessing native iOS and macOS components, or an expanding array of Cupertino-style widgets, building iOS apps with Flutter is an excellent option.
Dart 3.5: Elevating Language Interoperability
Simplified Interoperability
When it comes to Dart, there have been significant advancements in language interoperability, whether with C, Java, Kotlin, Objective-C, or Swift. This is a major advantage, as it streamlines the integration of native APIs and libraries. Additionally, Pub.dev keeps evolving, making things more convenient for developers who depend on this extensive package repository every day, staying closely aligned with the needs of the dev community—an ongoing priority for Flutter.
Improving Pub.dev
Pub.dev, the official repository for Dart and Flutter packages, continues to get better with each update. Dart 3.5 ensures that developers relying on this vast package repository have an even smoother experience, always keeping an ear to the ground for the needs of the dev community—something Flutter has consistently prioritized.
Dart language & macros
Meanwhile, the Dart team continues working on the new macro functionality introduced in Dart 3.4. It's one of the most exciting aspects of Dart, as it will raise the level of abstraction in Dart programming.
As a Flutter and Dart developer, there's a huge opportunity today to start adopting the use of macros incrementally to create more reusable code. And when it goes into production next year, we'll be able to assimilate that change much faster. I believe this will have a huge impact on how we develop, and Dart will solidify itself as a very attractive language for developers through new features like this and the ones we've been seeing throughout the year. The developer experience remains very high, and the Dart team continues to expand its commitment to further improving it.
Conclusion
In short, Flutter remains a very solid choice in the market for building a wide range of applications across multiple platforms with a single codebase, without compromising performance or user experience thanks to the native look and feel of each operating system.
It's hard to summarize all the changes that these new versions bring because there are so many, and Flutter covers such a broad spectrum that you don't know where to start. But that's the beauty of Flutter: it allows you to learn and explore many scenarios, as it strives to offer the best on each platform it supports.
With Flutter 3.24 and Dart 3.5, the future of app development looks brighter than ever. These updates reflect a commitment to innovation, efficiency, and enhancing the developer experience. Whether you're building apps for iOS, macOS, or any other platform, these tools are designed to streamline your workflow and make your apps more powerful.
I hope you're as excited as I am! It's truly a great time to build apps with Flutter.
