无法在模拟器上运行 flutter 项目 - 文件名太长错误

在 VS Codium 中的模拟器上运行 flutter run 时，出现以下错误：

flutter run --debug
Launching lib/main.dart on sdk gphone64 x86 64 in debug mode...

我运行默认使用flutter create projectname.

如果我运行自己的代码，它也不会工作。

该目录中有很多名称很长的文件。我正在使用 Linux Mint。Flutter SDK 和 VS Codium 的 Flutter 插件是最新的。

尝试重新安装插件并重新安装 flutter SDK - 没有效果。我还尝试清理和重建项目或创建新项目 - 没有效果。

编辑尝试使用 Android Studio 代替 - 也行不通。

这个问题是由多种因素共同导致的：

您的文件系统（使用 eCryptFS 加密的 ext4）将文件名限制为 ~143 个字符
gradle 内部的编译器为嵌套闭包生成长文件名
flutter 3.16 中的最新更改导致该函数addTasksForOutputsAppLinkSettings使用许多嵌套闭包。

简而言之，这意味着：您无法在加密的 Linux Mint 文件系统上使用标准 gradle 设置来编译 flutter 3.16 项目。

不幸的是，没有简单的解决办法。您有以下选择：

禁用文件系统加密或将 flutter 项目移动到磁盘的非加密部分
更改 groovy 编译器的内部结构，以对生成的文件使用较短的文件名。
向 flutter 团队提出这个问题，并要求重构最近的 3.16 更改，这将导致嵌套闭包数量减少。

第三点听起来像是一个简单的解决方案，但只是暂时的。有人可能会（不）故意在下一次更新中重新引入大量嵌套闭包，并再次破坏加密文件系统上的构建。永久修复需要颤振维护者的长期支持。

第二种方法是一种很有前途的方法，因为它可以提供长期的解决方案。但这需要对编译器进行更改，这可能需要一些时间。

因此，短期内您剩下的就是：将您的项目（或至少是构建输出文件夹）移动到磁盘的非加密部分
