我将 image_picker 插件升级到最新版本，第一次应用程序正常运行，第二次它给我这个错误.所以我不明白错误是由这个插件还是其他原因引起的.如果我错过了，或者您需要一些其他信息，请告诉我.
附言.由于字符限制，我不得不删除 Xcode 输出的某些行，如果您需要完整的日志，请告诉我.
I upgraded the image_picker plugin to the latest version and the first time the app run properly, the second time it gives me this error. So I don't understand if the error is caused by this plugin or by something else. Tell me if I have missed or you need some additional informations.
Ps. I had to delete some lines of the Xcode's output because of the characters limits, if you need the complete log tell me please.
推荐答案
当项目位于 iCloud 目录中时，可能会发生这种情况，导致文件重复.我看到有两种解决方法:
This can happen when project is inside an iCloud directory, causing file duplication. There are two workarounds I see:
1- 从根项目中删除重复文件.始终先运行不带 -delete 的 find 命令，以确保您不会删除不需要的文件
1- Remove duplicate files from root project. Always run find command without -delete first to make sure you're not deleting unwanted files
find . -name \*\ 2.\*
find . -name \*\ 2.\* -delete
find . -name \*\ 3.\*
find . -name \*\ 3.\* -delete
flutter clean
flutter run
2- 使用以下命令清理/重新安装 Pod(在 Flutter 项目根目录上)
2- Clean/reinstall pods, with the commands below (on flutter project root)
cd ios
pod deintegrate
cd ..
flutter clean
flutter run
最终的解决方案是从 iCloud 目录中删除 flutter 项目.但是，我也在 iCloud 目录中使用它，以确保备份我的gitignored"文件.我也在寻找更好的解决方案.
The final solution would be removing flutter project from iCloud directory. However I also use it inside an iCloud directory, in order to make sure my "gitignored" files are backed-up. I'm also seeking for a better solution.
让我知道它是否有效.
