Desktop Windowing APIs
summary
Demonstrates Flutter’s new desktop windowing API that creates multiple native windows and renders to them in a single frame using Dart FFI synchronous single-frame window creation. Shows five concrete window types and an actual demo with 19 windows demo running smoothly across Linux, macOS and Windows, plus escape hatches to grab native handles. APIs are experimental and opt‑in via experimental feature flag opt-in; window controllers require manual disposal and engines add dirty‑view rendering optimizations.
