Flutter 3.3, the modern-day replacement for Google’s cross-platform app improvement kit, brings extra Material You widgets, an experimental new renderer that may also wildly velocity up your app, enhancements to Dart, and more.
First teased in 2015, Google’s Flutter has grown to end up what we name a “massively cross-platform” improvement kit, enabling the introduction of apps for Android, iOS, Windows, Mac, and many greater from a single codebase. Today marks the first day of Flutter Vikings, a community-led convention committed to Flutter and Dart, hosted in Oslo. To commemorate the conference, Google is releasing Flutter 3.3 which consists of a first-rate smattering of new features.
For followers of Google’s contemporary format language, Material You, Flutter 3.3 consists of a handful of newly up-to-date widgets, such as extra colorful Icon Buttons, Chips, and App Bars. For now, these redesigned widgets are optional, requiring you to opt-in to “useMaterial3.”

You can study the full set of adjustments in this replacement over on the reputable Flutter blog. Broadly speaking, though, even if you don’t see any essential upgrades that can also assist your cutting-edge project, Google is encouraging builders to replace Flutter 3.3 due to the fact of some significant overall performance upgrades for apps.
Looking to the future, with this cutting-edge release, Google is permitting Flutter builders to start checking out their new rendering layer, “Impeller.” Serving as a substitute for Flutter’s use of Skia, Impeller is set to supply Flutter apps a full-size performance increase throughout Android and iOS with no modifications wished to your code.
For now, the Flutter group is solely actively encouraging iOS builders to attempt Impeller with their apps and publish feedback.

The Dart crew was once additionally excited to share that builders have been swift to undertake the language’s null security features. As such, they’ve laid out plans to absolutely cast off aid for non-null-safe code, which will assist make Dart itself quicker and make future improvement easier. They’re giving builders masses of notice, with null security no longer set to emerge as a requirement till someday subsequent yr at the earliest.
Additionally, at the Flutter Vikings conference, the Flutter group shared that Eric Seidel, one of the co-founders and unique public faces of the undertaking given that its 2015 debut, is leaving Google. With Flutter now firmly mounted as a predominant participant in the app improvement space, Seidel is putting off on his subsequent journey whilst the relaxation of the group at Google is nonetheless firmly committed to Flutter’s future growth.
