Google recently announced the release of a new rendering engine for Flutter on iOS. This new renderer, called the Metal renderer, is designed to improve performance and enhance the user experience for iOS users.

Flutter is an open-source mobile application development framework created by Google. It allows developers to build high-quality, cross-platform applications for both Android and iOS using a single codebase. One of the unique features of Flutter is its use of a custom rendering engine, which enables fast and fluid animations and smooth scrolling.
However, Flutter’s custom rendering engine has posed some challenges on iOS devices, which use the native rendering engine, Core Animation. While Flutter apps have performed well on Android, they have sometimes lagged on iOS, causing some developers to shy away from the framework.
To address this issue, Google has developed a new rendering engine for iOS called the Metal renderer. This new renderer is designed to take advantage of the Metal graphics API, which is optimized for iOS devices. The Metal renderer replaces Flutter’s previous rendering engine on iOS, known as Skia.
The Metal renderer is expected to improve performance and reduce lag on iOS devices, making Flutter apps run more smoothly and enhancing the user experience. It is also expected to provide better support for iOS-specific features, such as the native scrolling behavior and the Safe Area insets.
Developers using Flutter will be able to take advantage of the Metal renderer by updating to the latest version of the Flutter framework and specifying the use of the Metal renderer in their code. Google has indicated that the Metal renderer will be the default rendering engine for iOS in future releases of Flutter.
The Metal renderer is just one of several recent improvements to the Flutter framework. Google has also released updates to the Dart programming language, on which Flutter is based, and has introduced new widgets and tools to simplify app development.
Overall, the Metal renderer is a significant improvement for Flutter on iOS devices. By taking advantage of the Metal graphics API, it provides a more optimized and efficient rendering engine for iOS, improving performance and enhancing the user experience for iOS users.
Flutter 3.7 has brought in some exciting new features and enhancements that make it even more powerful and user-friendly. Some of the major highlights include:
- Redesigned DevTools memory debugging tool: Three new feature tabs, dubbed Profile, Trace, and Diff, have been added to the RevTools memory debugging tool. The ability to analyse the current memory allocation for an app by class and memory type, discover which code paths are allocating memory for a group of classes at runtime, and compare memory snapshots to understand memory management between two points in time are all features offered by these tabs, which also support all previous memory debugging features.
- Improved Material 3 design system support: The Material 3 open source design system now has better support in Flutter 3.7, which also includes the migration of widgets such the Badge, BottomAppBar, Divider, Menus, Slider, and Banner.
- On the Performance page, under the Frame Analysis tab: It is now simpler to troubleshoot performance issues and improve your app thanks to the new Frame Analysis tab on the Performance page, which provides information for a chosen Flutter frame.
- Scrolling has been considerably enhanced because to new widgets like Scrollbars, refined trackpad interactions, and better handling of text selection in scrolling contexts.
- Improvements to memory management: Flutter 3.7 has made a number of changes to memory management to lessen jank brought on by garbage collection pauses, resulting in a more responsive and fluid user experience.
- Support for internationalisation has been updated, which makes it simpler to develop localised apps that cater to customers from various locations and languages.
With these new features and enhancements, Flutter 3.7 is an even more powerful tool for developers to create high-quality, performance-driven mobile applications.
[Why WebAssembly is becoming more popular | Why Wasm is the future of cloud computing]
- Wasm, also known as WebAssembly, is a binary instruction format used by web browsers to execute stack-based virtual machines. WebAssembly, which was first created to boost online application performance, has gained prominence and is now touted as the cloud computing technology of the future.
- In addition, WebAssembly offers greater isolation and security than conventional web technologies. The sandboxed environment in which WebAssembly executes makes it considerably more difficult for malicious code to elude detection and impact other system components.
- Additionally, WebAssembly may be used on a wide range of platforms, including desktop and mobile devices, and is very portable. As a result, it is a desirable choice for cloud computing, where programmes must be able to function on a variety of hardware and software setups.
- In general, the development of WebAssembly is encouraging for the future of cloud computing. We can anticipate seeing an increase in the number of applications produced with WebAssembly at their core as more developers become aware with the technology and its advantages.
