v0.3.0

Two packages go out together: nativeapi and cnativeapi.

nativeapi

• Breaking: requires Flutter 3.47 / Dart 3.13.
• Add package:nativeapi/windowing.dart: controller.nativeWindow / nativeWindowOf()
  turn a window created with Flutter's experimental multi-window API into a nativeapi
  Window, so Flutter-rendered secondary windows can be styled, positioned and observed
  from Dart alone. It is a separate library because it imports Flutter's internal
  windowing libraries, whose names change between releases; it follows the stable channel.
  Stable has no flutter config --enable-windowing, so an app switches the API on itself
  with isWindowingEnabled = true before its binding starts. See
  floating_toolbar_example, browser_tabs_example and detachable_window_example.
• Windows: a Window.backgroundColor with alpha now really makes the window see-through —
  the alpha was ignored before; the compositor draws the color. (macOS since 0.2.7.)
• Linux: a Window.backgroundColor with alpha makes a Flutter window see-through there
  too (the Flutter view's black backing takes the color), and Window.setParentWindow
  now reaches a Wayland compositor when the child happens to be shown before its parent.
• Linux: Window.titleBarStyle = hidden on a window that is not shown yet no longer
  leaves its content 52 px short in both directions on Wayland (it now hides GTK's own
  header bar instead of un-decorating the window).
• Linux: Window.hasShadow = false works on windows with client-side decorations — every
  toplevel on Wayland, and windows with a header bar on X11. A window the window manager
  decorates keeps its shadow, and hasShadow keeps saying so. contentSize of a window
  created by this library is no longer measured with the shadow margin and the title bar
  included on Wayland.
• Linux: building no longer asks for libayatana-appindicator3-dev (see cnativeapi).

cnativeapi

• Breaking: requires Flutter 3.47 / Dart 3.13.
• Android: the shared library is linked with 16 KB page alignment, so it loads on the
  Android 15 devices that use 16 KB memory pages.
• Linux: building no longer asks for libayatana-appindicator3-dev. The tray icon has been a
  StatusNotifierItem over D-Bus for a while; only the plugin's CMake file still required
  and linked the library.
• Update the embedded core: a translucent window background is see-through on Windows and
  Linux, native_window_set_has_shadow works on Linux, Linux hides GTK's header bar for
  titleBarStyle = hidden instead of un-decorating the window, and a Linux window's
  content size is measured without the shadow margin.
