Build runner 在 flutter drift 中没有按预期工作

Question

flutter packages pub run build_runner build --delete-conflicting-outputs 构建运行器非常适合 dao 文件并生成 .g.dart 文件，但包含数据库 class 和表

的文件除外

我的pupspec.yaml

dependencies:
  flutter:
    sdk: flutter
  drift: ^1.6.0
  drift_sqflite: ^1.0.0
  path_provider: ^2.0.0
  path: ^1.8.1
  json_serializable: ^6.2.0

dev_dependencies:
  flutter_test:
    sdk: flutter

  flutter_lints: ^2.0.1
  drift_dev: ^1.6.0
  build_runner: ^2.1.10

构建运行程序输出
