Fixed #

• Windows: the top band shrank by the full resize width, making the system paint a titlebar-black strip above the self-drawn titlebar. The top now keeps exactly 1px of non-client area (the DWM border line, bitsdojo's top -= 1 recipe), and top-edge resize is served by a self-computed HTTOP over the client top band.

Changed #

• Windows: customFrame redesigned from pure borderless (client collapses to the full window rect) to equal-width NC bands — the client shrinks by one DPI-scaled band on all four sides, giving:
  • self-drawn titlebar plus the system border (Win11 1px border and rounded corners survive, WS_CAPTION is never touched);
  • uniform 4-edge + 4-corner native resize bands (including the top edge, which upstream window_manager's hidden branch leaves dead on Win11);
  • no themed-border flash during drag-resize (the band is real non-client area, so the resize loop repaints the band itself);
  • fullscreen (both the plugin's own and an external WS_OVERLAPPEDWINDOW strip) collapses the band entirely — no NC area, no resize.
• No child-window subclass needed anymore (edge hit-testing is native); the child subclass from 0.1.x is gone.

Fixed #

• Windows: the themed border flashed back during a drag-resize. The graft now drops WS_CAPTION (keeping WS_THICKFRAME for native edge resizing) while enabled and restores the exact pre-graft style on disable — the Chromium/Electron frameless recipe. Without it, DefWindowProc repainted the non-client area computed from WS_CAPTION inside the resize modal loop, ignoring the WM_NCCALCSIZE return 0 mapping.

Initial public release.

Added #

• Verbatim port of window_manager 0.5.2's full Dart facade and event system (windowManager, WindowListener, 15 window events, 60+ methods), with the native Windows / Linux / macOS implementations ported mechanically.
• Custom frame takeover (WindowOptions(customFrame: true) or windowManager.setCustomFrame(bool), default off):
  • Windows: borderless WM_NCCALCSIZE (no themed border, no Win11 8px top inset), per-monitor-DPI four-edge/four-corner WM_NCHITTEST resizing (top edge included), cooperative WM_GETMINMAXINFO (minimum/maximum size enforced natively; maximized windows clamp to the monitor work area), and resizing force-disabled in fullscreen — covering both the plugin's own fullscreen state and an external fullscreen path that strips WS_OVERLAPPEDWINDOW.
  • Linux: reversible gtk_window_set_decorated toggle with snapshot restore.
  • macOS: reversible fullSizeContentView + transparent-titlebar toggle that keeps the .titled bit so the window stays key-capable.
• C++-only Windows implementation — the package has no win32 Dart dependency, unlocking win32 6.x/file_picker 12.x/ flutter_secure_storage 11.x in downstream apps.
• DragToMoveArea, DragToResizeArea, WindowCaption widgets from the upstream port.
