[image_picker] pickImage fails on image with markups on iOS 26 #185623
Description
Steps to reproduce
Deploy the provided minimal code sample to an iPhone 16 Plus or iPhone 17 Pro Max.
Open the native iOS Camera app and take a new live photo.
Open the iOS Photos app, select the new photo, and edit it using the native iOS "Markup" tool (draw on the image). Save the changes.
Open the Flutter app and tap the button to trigger ImagePicker().pickImage().
Select the marked-up photo from the gallery.
Our team tested it on iPhone 16 plus (OS version 26.2), iPhone 17 Pro Max (OS version 26.4), and iPhone 13 (OS version 26.3). The issue is only reproducible on iPhone 17 and 16.
Expected results
The image_picker plugin should successfully process the image and return a Uint8List representing the final, edited image (including the drawn markup).
Actual results
On the iPhone 16 Plus (OS 26.2) and iPhone 17 Pro Max (OS 26.4), the image_picker fails to process the image correctly. XFile is returned correctly but its an empty file.
However, when performing these exact same steps on an iPhone 13 (OS 26.3), the image is picked successfully with the markup edits intact.

Hi @artur-sitemanagerpro
Thanks for the report. I tested this on a physical iPhone 15 Pro Max and on an iPhone 17 Simulator, and in both cases the picker successfully returned the marked-up image. Since it works on the iPhone 17 Simulator but fails on your physical iPhone 17, this strongly suggests a hardware-specific encoding issue.
Routing to team-ios with an FYI to the ecosystem team so this can be investigated directly on physical iPhone 16/17 hardware.

Worth trying it out with a native app using UIImagePicker API directly.
hellohuanlin commentedon Apr 30, 2026
@mbcorona from triage: could you try out some native apps (e.g. iMessages) and see if it reproduces? Thanks

We are running into the same issue on iphone 17 Pro Max on iOS 26.5.
Any markup applied to an image on the iPhone, if you upload from that device, will show this error. If the image is sent off the native device where the markup originated, the image will work and upload.
Any markup options, shapes, pen, pencil and marker all cause the error for the image.
Note:
If you remove
The image will then succeed. It appears the issue is isolated to the image_picker compression, based on our investigation.
