我有这个flutter项目，我一直在工作，我需要代码生成的各种原因，如riverpod供应商和冻结模型。所以我使用build_runner包来生成这个.g.dart文件，但是当我运行dart run build_runner watch时，我突然得到这个错误：

[INFO] Generating build script completed, took 152ms
[WARNING] ../../../../../.pub-cache/hosted/pub.dev/riverpod_generator-3.0.0-dev.4/lib/src/templates/family.dart:230:48: Error: The getter 'metadata' isn't defined for the class 'AstNode'.
 - 'AstNode' is from 'package:analyzer/src/dart/ast/ast.dart' ('../../../../../.pub-cache/hosted/pub.dev/analyzer-6.2.0/lib/src/dart/ast/ast.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'metadata'.
    final meta = metaAnnotations(provider.node.metadata);
                                               ^^^^^^^^
[INFO] Precompiling build script... completed, took 625ms
[SEVERE] Failed to precompile build script .dart_tool/build/entrypoint/build.dart.
This is likely caused by a misconfigured builder definition.

我已经看到了关于这个问题的几个帖子，但任何建议的答案似乎都有效。所以我尝试了几件事：dart run build_runner build --delete-conflicting-outputs删除pubspec.lock文件flutter clean和flutter pub get使用flutter pub upgrade将软件包升级到最新版本添加analyzer依赖包，如一篇文章所建议。尝试dart run build_runner doctor，但得到相同的输出。我还尝试了flutter chache repair和flutter pub get，并手动删除该高速缓存存储int .dart_tool/目录，但没有任何工作。我已经被困在这几个小时没有用，我不知道什么可能是错的。这是我的pubscpec.yaml文件
