我将 Flutter 从 2.5 升级到 2.8，当我运行应用程序时出现以下错误：

【问题讨论】：

首先，使用flutter clean 清理构建文件，然后使用flutter pub get 再次获取发布包。如果之后问题仍然存在，请运行flutter pub cache repair 命令以适应所有缓存的 pub 包的新更改。

Flutter 只需要清理一下。正如@ashok 正确提到的那样。您需要清理以前的构建并清除缓存。然后运行构建命令。它应该编译。如果不让我们知道

我也遇到了这个问题，我决定暂时降级到 2.5.3 @MichaelTran

【参考方案1】：

据我所知，他们已将 six_ft_... 重命名为 six__ft_...，注意双下划线。

在他们修复之前，您可以在包的本地副本中手动更改它。

其他没用的，也删掉就好了。

【参考方案2】：

当我将我的颤振升级到 2.8 时，它只需要从 android sdk manager tools 下载 cmdline-tools。 如果您仍然没有下载它，请尝试下载它。 然后 将 android-sdk/tools 路径添加到环境中

祝你好运

【参考方案3】：

运行 flutter clean 并使用 flutter pub get 重建 Flutter 项目应该有助于映射项目缺少的构建文件。这个技巧对我很有效。
