"Flutter: How we're building a UI framework for tomorrow at Google"
summary
A new UI toolkit called Flutter paints every pixel, handles every gesture, and ships to iOS and Android by compiling Dart straight to ARM while using Skia for GPU drawing. It promises hot reload for sub‑second code-change‑to‑live development, favors composition over inheritance with immutable widgets, and exposes low‑level layers for customization. Early adoption already exceeds 100 apps and includes a Hamilton release with over a million installs, so the system actually works.
