Build fails on latest Flutter: $Container missing implementation for new Container.isAntiAlias member

[DaoChiMinh]

After upgrading to the latest Flutter SDK, any project using flutter_eval fails to compile. The Flutter framework recently added a new isAntiAlias field to the Container widget (packages/flutter/lib/src/widgets/container.dart), and the generated bridge class $Container does not implement it.

Error log:
Error: The non-abstract class '$Container' is missing implementations for these members:

• Container.isAntiAlias
  Try to either
• provide an implementation,
• inherit an implementation from a superclass or mixin,
• mark the class as abstract, or
• provide a 'noSuchMethod' implementation.
  class $Container implements Container, $Instance {
  ^^^^^^^^^^
  ../../../flutter/packages/flutter/lib/src/widgets/container.dart:332:14: Context: 'Container.isAntiAlias' is defined here.
  final bool isAntiAlias;

Target kernel_snapshot_program failed: Exception
Execution failed for task ':app:compileFlutterBuildDebug'.
Environment:

flutter_eval: ^0.8.2
dart_eval: ^0.8.5
Flutter: 3.44
Platform: Windows 10/11, building for Android (debug)
Steps to reproduce:

Create a Flutter project on the latest Flutter SDK
Add flutter_eval as a dependency
Run flutter build apk --debug (or flutter run)
Build fails at kernel_snapshot_program with the error above

Expected behavior:
The $Container bridge class should implement the new Container.isAntiAlias getter (and ideally expose the new isAntiAlias constructor parameter) so the package compiles against current Flutter versions.
