Flutter 3.47 decouples Material and Cupertino into standalone packages
What's New in Flutter 3.47

Flutter 3.47 marks a major milestone by releasing material_ui and cupertino_ui as standalone 1.0 packages, decoupling design systems from the core SDK. The update also brings Impeller to desktop by default, prepares for Apple's Xcode 27 with raised minimum OS versions, and graduates Widget Previews to stable. Developers can migrate using dart fix, and the release includes experimental multi-window support and flavors for desktop.
By opting into the decoupled design systems, you gain control over your design roadmap.
