However, on iOS, due to the limitations you've outlined in your FAQ, one must copy the file or directory to a temporary directory for access.

An issue arises with FilePicker.platform.getDirectoryPath(); on iOS, where it moves the directory instead of copying it, contrary to the expected behavior. As a result, the user will permanently lose access to that directory.

This issue is stale because it has been open for 14 days with no activity.

The FilePicker works fine on Android but on iOS it crashes my app with no permission to access "tmp", whether I want to pick an internal directory or an iCloud.

iOS 15.3.1

Error log after picking a folder "Test" in the internal directory structure:

“Test” couldn’t be moved because you don’t have permission to access “tmp”.

Exited.

Why is it even trying to move the "Test" directory? I just picked it as a target to save a file into at a later step, nothing else...

any updated here ? I met same issue :(

Answer 5 · 2024-02-17T23:34:17.000Z

very frustrating this issue is seemingly ignored. this library is basically the only way to access files/folders with flutter

Answer 6 · 2024-02-18T05:41:58.000Z

Same here, any solutions? @miguelpruivo

Answer 7 · 2024-02-18T09:48:01.000Z

I tested some older versions of this library and it seems to yield the same issue, perhaps there has been a breaking change in newer iOS versions?

This issue is stale because it has been open for 7 days with no activity.

Answer 12 · 2024-03-20T12:06:03.000Z

What's the status of this? Haven't experienced any issue in the meantime. Does this only happen on iOS 17.0? I'm not sure if I correctly understood the issue, it doesn't pick the path, is that it?

Answer 13 · 2024-03-20T12:12:43.000Z

@miguelpruivo The issue is present on iOS 15 and newer, not Android. Picking any directory results in the missing permissions for "tmp" error message for me (as seen in my error log above), not sure about what others get.

Answer 14 · 2024-03-20T12:24:40.000Z

I guess I'll have to try to replicate in order to fix it or some issue a PR.

Any reproducible example or steps to?

Answer 15 · 2024-03-20T12:30:53.000Z

Simply calling FilePicker.platform.getDirectoryPath(); and picking -any- directory, whether internal or on iCloud, was enough for me. The issue happened every time.

Answer 16 · 2024-03-20T12:35:57.000Z

For me on real devices the issue is reproducible. Works fine for simulator.

Answer 17 · 2024-03-20T16:11:55.000Z

Simply calling FilePicker.platform.getDirectoryPath(); and picking -any- directory, whether internal or on iCloud, was enough for me. The issue happened every time.

But what is exactly the issue?

Answer 18 · 2024-03-20T18:44:16.000Z

@miguelpruivo selecting the directory crashes the app and throws the error that I pasted above.

Answer 19 · 2024-03-20T19:13:53.000Z

hey @miguelpruivo, sorry for the late replay.

When invoking FilePicker.platform.getDirectoryPath(); on Android, it successfully returns the actual path of any selected directory.

However, on iOS, due to the limitations you've outlined in your FAQ, one must copy the file or directory to a temporary directory for access.

An issue arises with FilePicker.platform.getDirectoryPath(); on iOS, where it moves the directory instead of copying it, contrary to the expected behavior. As a result, the user will permanently lose access to that directory.

This concern is addressed in the issue that I've opened.

Edit:

This making me wonder if we was able to move the original folder why we are copying the file in first place?

Here is the error

I think problem is that it's trying to move the directory, I did not find a way to add permissions to tmp, everything points that it's already should be granted.
