Flutter 3.24 Released: Impeller Progress and the Flutter GPU Preview

What happened

Flutter 3.24 was released on August 7, 2024, at I/O Connect Beijing, according to the official Flutter documentation's archive of releases. It shipped alongside Dart 3.5 and was accompanied by both an umbrella and a technical blog post from the Flutter team.

Widgets and platform support

The release expanded the widget catalog, adding the new CarouselView widget and 37 previously missing widgets to the Cupertino catalog, along with updated behaviours for CupertinoButton and CupertinoTextField. It added support for new platform features: on Android 14 devices Flutter apps could support the predictive back gesture, and for the then-beta iOS 18 it enabled iOS app extensions for custom Control Center toggles and tinted app icons.

Impeller and Flutter GPU

Flutter 3.24 continued the transition to Impeller, Flutter's modern rendering engine, which would become the default on iOS and Android in the following release. The release also introduced the new experimental Flutter GPU API, a lower-level graphics API for developers who want more direct control over rendering, described in a dedicated blog post.

Tooling and Swift Package Manager

The release added guides for adding Swift Package Manager support to iOS plugins and apps, though Flutter continued using CocoaPods until all of an app's dependencies were migrated. It also updated web embedding docs, including enabling multi-view mode and embedding web content into a Flutter app, and shipped DevTools updates across versions 2.35 through 2.37.

Why it mattered

Flutter 3.24 was a steady, feature-rich release that advanced Flutter's rendering story through Impeller and the experimental Flutter GPU API while keeping pace with new iOS and Android platform features. New widgets like CarouselView and continued Swift Package Manager work reflected Flutter's ongoing maturation as a cross-platform framework.
