Research direction

Start by locating the Window API and the platform-specific implementations for Windows, Linux, and macOS. Compare the proposed Windows GetSystemMenu/TrackPopupMenu and Linux gdk_window_show_window_menu behavior, and document the macOS limitation. Done means ShowSystemMenu(Point) works at the requested position with correct Windows item states and is documented where unsupported.

Description

enhancement

There's no API to show the system window menu (restore / move / size / minimize / maximize / close) at a point. Apps with a custom title bar need it for right-click on their drag area, and for Alt+Space on Windows. window_manager's popUpWindowMenu() is a no-op in 0.6.0 because of this.

Proposal: Window::ShowSystemMenu(Point). On Windows, GetSystemMenu + TrackPopupMenu, with the item states (restore/maximize enabled) kept correct. On Linux, gdk_window_show_window_menu(). On macOS, no equivalent (document it). Then DragToMoveArea in nativeapi-flutter can open it on secondary click.

Background:

leanflutter/window_manager#562: popUpWindowMenu not working
leanflutter/window_manager#532: right-clicking the DragToMove area should show the window context menu
leanflutter/window_manager#151: menu item states shown incorrectly on Windows
