flutter - flutter pub run build_runner build 时出错

Question

我在运行 flutter pub run build_runner build 时遇到了这个问题。我尝试过类似 flutter clean、flutter pub-cache repair、flutter pub get 等解决方案。在 pubspec 上添加了 Mockito、HTTP 和 build_runner 等依赖项，flutter pub get 也成功运行。

Failed to precompile build_runner:build_runner:

      return kinds.contains(TargetKind.topLevelVariable);

添加分析器 https://pub.dev/packages/analyzer pubspec yaml 的开发依赖项中的依赖项 1.5.0 对我有用

 dev_dependencies:
   analyzer: 1.5.0
