desktop_window_bootstrap

Minimal desktop window bootstrap helpers for Flutter desktop apps.

Windows Client Area

applyWindowsClientAreaLayout adjusts the native Windows outer HWND so the Flutter client area matches a design window size after a caller-supplied top inset is removed.

The inset is intentionally not owned by this package. Apps that design against a macOS full-size-content window should pass their own macOS titlebar/safe-area height, for example 32.

await DesktopWindowBootstrap.applyWindowsClientAreaLayout(
  windowSize: const Size(1080, 720),
  minimumWindowSize: const Size(1080, 720),
  contentTopInset: 32,
  center: true,
);

With those values, Windows targets a Flutter client area of 1080 x 688. getWindowsClientAreaSize() returns the current Windows client area in logical pixels for resize reconciliation.
