window_manager through its 0.5.x compatible API
(package:window_manager/legacy.dart): one window driven by the classic
windowManager calls and a WindowListener.
That API is deprecated and will be removed in a later release; it is shown here for apps that are still on their way to the native API.
lib/window_controller.dart— everywindowManagercall and the listenerlib/main.dart,lib/widgets/— the window: one row of choices per group of calls, the geometry read back from the system, and a log of the listener callbacks. Built onpackage:flutter/widgets.dartalone.
flutter run -d macos
flutter run -d linux
flutter run -d windowsThis one is deliberately small. Several windows at once, parent and child windows and every native property with read-back are in nativeapi's window_example.
