目标 kernel_snapshot 失败：异常：创建快照期间出错：null 构建失败

Question

我已经更新到最新的 flutter 更新了。当我想启动项目时，它返回一个错误。该项目依赖于几个存储库，我不知道这是否是原因。我尝试了多种解决方案，但都没有解决该错误。希望可以有人帮帮我。谢谢。

我发现这个问题 TL :DR 这里是一个总结

看起来您的本地引擎构建 flutter/engine 和框架 + 工具 flutter/flutter 不同步：您使用的是添加后的引擎SemanticsFlag.isLink，但使用的是添加到框架之前的框架/工具。

您需要确保使用兼容的引擎和框架。在这种情况下，您需要将 flutter/flutter 更新到较新的版本，或者将 flutter/engine 回滚到较旧的版本。42356
