Google scrolls and folds Flutter to version 3.13

The latest release sees performance improvements to its Impeller graphics renderer, APIs for foldable devices (for example, reporting the physical size, the device pixel ratio, and the refresh rate of the display), supporting wide-gamut colours, updates for Material 3, the latest version of Google’s design system (more customisation enabled for widgets), and support for two dimensional scrolling on widgets (including a new interaction of diagonal scrolling).

Kevin Chisholm, a Technical Program Manager for Dart and Flutter at Google, writes on Android support targets:

“With this release, Flutter now supports targeting Android 14/ API 34. While we are still working on a few new features in Android 14 (i.e. predictive back navigation), we have thoroughly tested this release against the new Android SDK and prioritize fixing any related issues you may find.”

He adds, in a ‘Breaking changes and deprecations’ section:

“Flutter no longer supports the Android Jelly Bean API levels (16, 17, and 18). The good news is that most apps should be migrated to this new minSdkVersion by default.”

Version 3.10 was released in May 2023, adding improved graphics performance.
