What's new in Flutter 3.44

Changing RawMenuAnchor close order

Closing a `RawMenuAnchor` now triggers the `onCloseRequested` and `onClose` callbacks for all descendant `RawMenuAnchor`s. The `onCloseRequested` callback is triggered top-down, starting from the triggering `RawMenuAnchor` and moving to its descendants, while the `onClose` callback is triggered bottom-up. If a `RawMenuAnchor` is already closed, calls to `MenuController.close` and `MenuController.closeChildren` don't trigger the `onCloseRequested` callback.

IconData class marked as final

The `IconData` class is now marked as `final`, which prevents it from being implemented or extended. This change is part of an effort to generalize the mechanism for tree-shaking assets and native code.

Large screen orientation and resizability restrictions ignored on Android 17

For apps targeting Android 17 or higher, orientation, resizability, and aspect ratio restrictions no longer apply on displays with width 600dp or greater. This means that `SystemChrome.setPreferredOrientations` is ignored on these devices.

ListTile reports an error in debug when wrapped in a colored widget

When a widget with a non-transparent background color, such as a `Container` or `ColoredBox` that sets `color`, sits between a `ListTile` and its nearest `Material` ancestor, the framework now reports an error.

Page transition builders reorganization

`CupertinoPageTransitionsBuilder` has been relocated from `package:material_ui/material_ui.dart` to the Cupertino package, which is now in `package:cupertino_ui/cupertino_ui.dart`.
