iOS Issues: autoCorrectionAngle not automatically enabled and manual rotation not saved​

[rigonijunior]

I would like to report an issue I am facing when using the flutter_doc_scanner package on iOS devices. I noticed that the autoCorrectionAngle functionality is not being automatically activated during image capture. Furthermore, even after manually rotating the image, the adjusted position is not saved correctly.

Steps to reproduce the issue:

1. Use flutter_doc_scanner on an iOS device to capture an image.

2. Observe that the captured image does not apply the automatic angle correction (autoCorrectionAngle).

3. Manually rotate the image to the correct orientation within the application.

4. Save the image and verify that the manually adjusted orientation was not maintained.

Expected behavior:

• The autoCorrectionAngle function should automatically adjust the image orientation during capture.

• If manual adjustment is necessary, the corrected orientation should be saved and reflected in the final image.

Current behavior:

• autoCorrectionAngle is not applied automatically.

• Manual rotation adjustments are not preserved after saving the image.

Additional information:

• This issue has been observed on iOS devices with the latest versions of the operating system.

• Other plugins, such as image_picker, also face similar image rotation issues on iOS.

Thank you for your attention and I am available to provide more details or perform additional tests that may help in resolving this issue.

Thank you for reporting this issue and providing detailed steps to reproduce it. I appreciate your effort in identifying this behavior on iOS.

Currently, the autoCorrectionAngle feature is expected to adjust the image orientation automatically, but I understand that it’s not functioning as intended. Additionally, I see that manually rotated images are not saving their adjusted orientation, which should not be the case.

I’m already working on similar functionality and improvements related to image processing and corrections, so I’ll take this issue into account as well. Fixing rotation inconsistencies, especially on iOS, is important for a smooth user experience. Other plugins, like image_picker, also face similar issues, and I’ll be exploring ways to handle this better within flutter_doc_scanner.

I truly appreciate your feedback, and if you have any additional insights, feel free to share. I’ll be working on this, and updates will be shared soon. If you’re interested in contributing, you’re also welcome to submit a PR, and I’d be happy to review and merge it! 🚀
