Target kernel_snapshot failed: Exception

FAILURE: Build failed with an exception.

* Where:
Script '/Applications/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 1201

* What went wrong:
Execution failed for task ':app:compileFlutterBuildRecDebug'.
> Process 'command '/Applications/flutter/bin/flutter'' finished with non-zero exit value 1

字符串
所以这意味着它没有找到flutter_test包。
我试过删除pubspec.lock，flutter clean和pub get，
我已经尝试了Flutterpub缓存修复和Flutterpub缓存清理.我试图删除位于.pub-cache/hosted/pub.dev的文件夹，但没有任何工作.总是相同的错误
你能帮我解决这个问题吗？
Thanks in advance
