this is my logs

[miguelpruivo]

@NukanTran Thank you. What’s the android version?

[NukanTran]

Android 8.0 in Genymoution

[miguelpruivo]

Android 8.0 in Genymoution

@NukanTran I might take a look into it later on. However, you are free to use the version on the beta branch because it's ahead of the master and has some updates.

[miguelpruivo]

@NukanTran @sonathati @zean00 apparently there are some files started with "raw" string that may lead to this issue on Android 8.0. Doesn't seem to happen with other versions though.

I couldn't replicate the issue, however I'm PR a fix to the beta branch and maybe later today merge a version 1.0 on the master along with dart pub update.

Let me know if it worked for you.

edit: version 1.0 it's now live with the fixes on dart pub, thank you for your feedback.

[starction]

@miguelpruivo I just tried 1.0.2 from pub and build fails

[miguelpruivo]

@sonathati glad that you’ve spotted it. I know what it is, that’s something that shouldn’t had been committed, probably due to a later git squash, my bad. I’ll fix it later today.

[miguelpruivo]

@sonathati everything should be working fine by now on 1.0.3, let me know if you find anything else.
Sorry for any inconvenience.

@miguelpruivo I am not able to get the file name when picked from open from view. But Iam able to retrieve the file name when attached from file manager available in the drawer

[miguelpruivo]

@sonathati I believe that is already fixed in the beta branch, could you give it a try? (You’ll need to add to your pubspec by using a git ref dependency).

[starction]

@miguelpruivo I have tried in latest beta branch by adding git ref dependency in my pubspec. But still not able to get the file name. Following are the logs

[miguelpruivo]

Hi again @sonathati , this seems to be a very specific/tricky issue that might be related to the path of downloads folder or a disabled download manager. Anyway, I've committed an update that tries to solve or, at least, try to understand the issue. Could you clean & build with the beta again, to give it a try?

Thank you.

[starction]

@miguelpruivo I could see issue still exists with the latest update, beta branch.
Issue is not seen for the same file attached from different view. Attaching the logs for file StoreList.pdf for both uploading URIs

Working case:

[miguelpruivo]

Can I ask you where actually you’re trying to load the second path? I remember having an issue where some androids would display email attachments on the recent files but the files weren’t actually there, it was like a placeholder.

Also @sonathati, can you clean and try with file_picker: ^1.1.1 that is already on the dart pub?

[pushangupta]

@miguelpruivo I have noticed that this bug started from image_picker provide by flutter team. You are right about the disabled downloads manager. But one thing I noticed in your version was that file picker works great when the file type is set to any. But as soon as file type is set IMAGE, it fails and gives the fatal exception. I think when we fail to retrieve the file path, we must copy the file to the cache directory and then get the path from there. It seems you are already implementing this for documents but since you are using image_picker as the source for picking files, it fails.

[miguelpruivo]

Thank you for the insights @pushangupta can you confirm if you are using FileType.CAMERA or FileType.IMAGE when this issue happens @sonathati?

[pushangupta]

@miguelpruivo FileType.IMAGE

[pushangupta]

@miguelpruivo Brother I did a little experiment. I changed the FileType to CUSTOM and gave file extension as JPG and guess what.. It fetched the exact same file it was failing on. Just a quick suggestion. If multiple file types(like JPG, PNG, SVG or JPEG) could be supported at the same time it would be better

[miguelpruivo]

@pushangupta that’s why it has the FileType.IMAGE, so it can filter all image file types at once, otherwise it wouldn’t make sense.

[pushangupta]

@miguelpruivo I mean, FileType.IMAGE surely uses image_picker... right? I am trying to avoid image_picker. Moreover if, for example, I wanted to select docs of extensions pdf, docx or ppt only what can I do?

[miguelpruivo]

@pushangupta right now you’d have to use FileType.ALL for that matter, but it’s a good suggestion that in a future update I add a FileType.DOC or so that will gather all of those file types in a filter at once.

[starction]

@miguelpruivo I had faced this issue with FileType.PDF
I have tried with file_picker: ^1.1.1 and its working fine for documents(using FileType.CUSTOM and fileExtension:'pdf') and for other FileTypes aswell except for FileType.IMAGE.

For FileType.IMAGE my App crashes when trying to upload image with URI: content://downloads/public_downloads/3411

[miguelpruivo]

@sonathati this looks like an issue from image_picker plugin then, since that is what’s used when type is either IMAGE or CAMERA. You may want to report it on the image_picker official repo.

[tiholic]

_info_: related issue from image_picker repo: https://github.com/flutter/flutter/issues/21863

[tiholic]

@miguelpruivo there is a fix available as separate package.
Can you create a temporary branch with reference to https://pub.dartlang.org/packages/image_picker_modern instead of image_picker so that we can reference to that branch directly via git in pubspec?

[miguelpruivo]

@tiholic thank you for pointing it. It may be a possibility, I'll take a look when I have sometime, feel free to give it a try and PR if you find it fixing the problem while keeping all of the required features.

[tiholic]

Sure, I'll try and let you know

[tiholic]

It works great. I've tested for images, videos and pdf's.

https://github.com/miguelpruivo/plugins_flutter_file_picker/pull/26

[miguelpruivo]

@tiholic does it fix this specific issue?

[tiholic]

Yes, now we can pick all types of files from downloads

[tiholic]

https://github.com/flutter/flutter/issues/21863

Issue closed, you can update the version.
