未能预编译build_runner:build_runner：

Question

我创建了一个新项目，在启动它时添加了依赖项，运行build_runner构建：

/C:/Users/Michael/AppData/Roaming/Pub/Cache/hosted/pub.dartlang.org/analyzer-1.6.0/lib/src/error/best_practices_verifier.dart:1600:40: Error: Getter not found: 'topLevelVariable'.
      return kinds.contains(TargetKind.topLevelVariable);
                                       ^^^^^^^^^^^^^^^^

      case TargetKind.topLevelVariable:
                      ^^^^^^^^^^^^^^^^

      case TargetKind.topLevelVariable:
                      ^

    switch (this) {
            ^

我已经阅读了堆栈溢出的所有内容，但我还没有找到解决方案。有什么想法吗？

指定分析器版本

analyzer: 1.5.0

警告:不要使用最新版本，因为它依赖于meta包，就像flutter_test一样--在这里您不能指定版本
