Flutter 3.44 launches with major updates across all platforms. Key highlights include Hybrid Composition++ (HCPP) for Android enabling high-performance native view embedding via Vulkan, Swift Package Manager replacing CocoaPods as the default for iOS/macOS, and improved Impeller/Vulkan rendering. Developer experience gets a boost with Agentic Hot Reload (MCP server integration for AI coding agents), Agent Skills for Dart and Flutter, and Genkit Dart preview for building AI-powered apps. Material and Cupertino libraries are frozen ahead of decoupling into standalone packages. Desktop sees experimental multi-window windowing APIs with Canonical as new lead maintainer. Notable real-world deployments include the 2026 Toyota RAV4 multimedia system and upcoming LG webOS SDK. Flutter now claims 1.5 million monthly developers and second-most-popular mobile SDK status.
