Flutter 3.44: Scaling to more users on more devices! Empowering developers at Google I/O 2026 Flutter 3.44 is here, and it's a big one! This release celebrates a milestone in the Flutter timeline: Hybrid Composition++ for Android, Swift Package Manager as the new iOS/macOS default, and improved Vulkan support for Impeller. We're previewing multi-window desktop support with Canonical as our new lead maintainer, and embarking on a major architectural evolution by decoupling Material and Cupertino from the core framework. We're redefining UX for agentic user experiences with GenUl and reimagining developer experience with Agentic Hot Reload and Dart & Flutter Agent Skills.

In this release cycle alone, we've landed 972 commits from 178 unique contributors, including 61 new contributors landing their
