Could you please post the stacktrace?

[Jamesfleming1]

Okay I will get on that, I guess I need to update my environment to run iOS 15 so that might take me a bit.

Hi,
I'm with the same problem here it is my stacktrace:

Thank you I’ll take a look!

Just tried it with a simulator and it works just fine with iOS 15 and live photos. What are the environment you are running on? And how are you picking?

[Jamesfleming1]

Ios 15, I'm running on an iPhone 7, have reports of it on iPhone 12 mini and iPhone 12 all on iOS 15.

[Jamesfleming1]

Are you able to try on an actual device?

[miguelpruivo]

Yes, just tried it on a device running iOS 15 and it works just fine. Could you please try sharing the picture you are trying to pick on? (you'll have to export it while keeping the original data so it doesn't converts to JPEG).

[Jamesfleming1]

Here is my call in code

FilePickerResult result = await FilePicker.platform
.pickFiles(
type: FileType.image,
allowMultiple: allowMultiple,
allowCompression: true)
.onError((error, stackTrace) {
print(error);
print(stackTrace);
return Future.error("PickingError");
});

And it gives me this issue
flutter: FileSystemException: Cannot open file, path = '/private/var/mobile/Containers/Data/Application/008FA7A9-1A0E-4930-8E34-D4D0420BC846/tmp/IMG_0020.pvt' (OS Error: Is a directory, errno = 21)

Hopefully that helps. I'm not sure how to actually send a Live Photo without converting it to live image. But it happens on every single live image so I really don't think its an issue with specific image

[shreymahendru]

Was investigating this today. This happens because .pvt is somewhat of a directory (Private Live Photo Bundle), and it contains 3 files. Check the image.

The HEIC (the Image), .MOV (the video), and a metadata file.
So when you copy over the file the .pvt "file" is a directory, with 3 files in it.
@miguelpruivo This is where the URL is converted to a directory URL

I am working on a workaround for that, where I covert the HEIC image into a JPEG and return an updated file URL rather than a .pvt. But that might be beyond the scope of this plugin.

Here is a naive solution:
shreymahendru@e2e78e8#diff-b036603fcfe6200abcc45e1c42269d040727e675911d0d8b6c8d8dcc4505aea7

Or For retrieving the HEIC Image (which seems better since you don't lose the metadata):
shreymahendru@8c72eeb

[miguelpruivo]

In my testing, the files picked where actually the .pvt which are expected. It's up to the developer to then extract/handle those files. The picker only allows you to pick the files as they are.

The problem is that after picking, you may need to extract, like @shreymahendru. The only two approaches I can see here is leaving as it is, or converting it automatically to JPEG, for example, but then again, some devs may want to the live photo for their applications and this would prevent it.

[miguelpruivo]

As a purposed solution whenever the developer has allowCompression set to true I'll extract it to JPEG and if the dev wants the .pvt file, just need to set the allowCompression to false and the file is fetched as it is.

How does that sound to you?

[brunoda6]

for me it's perfect thanks

looks great to me!

I saw this issue on ios 15. on ios 14 seems to work fine. Got lot of crashes on sentry during this week

Good catch guys!

[miguelpruivo]

Fixed and published with 4.1.3. I took advantage of some of the work that @shreymahendru made by converting Live Photos into static JPEG. Thank you! 🎉

[Jamesfleming1]

Awesome!!! Thanks everyone!

[davidfranquet]

thanks!!!

[urusai88]

Can you fix it to work without compression?
