![]() ![]() That's the same as Swift, but unlike Kotlin, which can't guarantee null safety for libraries. Starting as a "mixture of JavaScript and Java", it now has features neither of these two languages do (such as sound null safety).ĭart introduced sound null safety in March 2021, covering both applications and libraries. What's New in Dart 2.18ĭart is strongly typed and optimized for UI development. Unfortunately, both numbers lack context, such as how competing platforms perform. This time the Flutter team said that "every day, more than 1,000 new mobile apps using Flutter are published to the Apple and Google Play stores". When announcing the previous release, the Flutter team cited the existence of 500,000 Flutter apps as a success indicator. In contrast, Impeller is custom-built for Flutter and "takes full advantage of modern hardware-accelerated graphics APIs such as Metal on iOS and Vulkan on Android." That enables better animations and removes a common source of "yank" – stuttering animations and transitions. Skia powers Chrome, Firefox, Android, ChromeOS, and more. That's why Flutter will also remove Bitcode support in a future release.įlutter has used Skia as its graphic engine since the very beginning. The upcoming Q4/2022 Flutter release won't work on macOS 10.11 (from 2015) and 10.12 (from 2016), either.Īpple dropped Bitcode from its upcoming fall iOS and iPadOS versions. That excludes iPhone models 5C (from 2014) and earlier and the 2nd through 4th generation iPad (the latter launched in 2012). The Flutter Visual Studio Code extension and the Flutter DevTools have also improved.įlutter 3.3 doesn't run on 32-bit iOS devices anymore. The Flutter team's go_router package simplifies routing within an app with URL-based declarations. And pointer compression is now disabled on iOS to make more memory available to non-Dart parts of a Flutter app (such as libraries). Loading images that are included in the app is faster and uses less memory with the new ui.omAsset() method. Some Material 3 components improved in this release: IconButton, Chips, and AppBar. And iPad apps can use Scribble with Apple Pencil for handwriting input. Windows apps now get their version number from the pubspec.yaml build file. Trackpad gestures work better in desktop applications. Text selection in Flutter web apps now works as expected – users can select multiple rows of text at once. Open-source libraries offer Windows, macOS, and Linux UI element sets. Flutter ships with Material UI, which works on all platforms, and an iOS UI element set. What's New in Flutter 3.3įlutter apps do not use UI elements of the underlying platform, but emulate them. Google also launched a new showcase app, Wonderous, built with Flutter 3.3 and using Impeller on iOS. ![]() A new rendering engine called Impeller is available, but only in preview and only for iOS. ![]() Both releases are refinements without significant new features. Google just announced the third Flutter release of 2022, version 3.3, and version 2.18 of Flutter's language Dart. With Google's UI framework Flutter, users can build natively-compiled applications for mobile, web, and desktop from one codebase. ![]()
