Custom window chrome with the two drag widgets of nativeapi:

• DragToMoveArea — the coloured bar moves the window; a double click maximizes and restores it.
• DragToResizeArea — the tinted frame is eight native resize handles (four edges, four corners). They are inset from the window edge on purpose, so it is clear the widget does the resizing, not the native frame. The button switches enableResizeEdges between all handles and right/bottom only.

The native title bar and window buttons are hidden, the minimum size is 480 × 320. The bar and the frame are drawn by the example from the DazzUI theme; everything around them is DazzUI (the examples' shared dazzui_host).

flutter run -d macos   # or windows, linux

The real-desktop test of this example lives in the workspace repository: tools/gui/flutter_window_drag_areas_test.py (macOS) and .ps1 (Windows). It presses in the middle of the handle bands, so keep kResizeEdgeSize and kResizeEdgeInset in lib/main.dart in sync with it.
