image_gallery_saver | flutter中用于保存图片到相册的Plugin | Computer Vision library

I'm facing an error that all the plugins that I implemented after a certain date won't work. I tried all the methods(reinstall, flutter clean, rebuild...) on the internet but none of them work, so maybe I'm in a very bizarre situation.

This is my yaml file:

Just about any mobile app framework seems to have the ability to download files to the "Downloads" directory, except for Flutter. Or is it just me?

Since Android SDK 29 it appears Flutter (Android) has taken the direction of only allowing files to be downloaded to the scoped application directory or the application's temporary cache directory. I could be totally wrong on this, which is why I am posting on SO, in the hopes I am.

You can download on Android, but the problem is you would have to write a tutorial for a user to try to find anything you downloaded because of where you can download files in Flutter. Either to the inaccessible except by app applications directory or the impossible to find application temp cache directory.

1. First question, why is there not a simple way to gain permission and download files on Android to the Downloads or media directory? Or better yet a dialog where the user can pick where they want to download files. I get security but Slack app does it somehow.

On Slack's app I can download a file and it will save to Downloads. Not a big deal.

There is lots of advice on SO about flutter packages that are outdated:

• ext_storage is outdated and even if you could get the downloads directory path you couldn't write to it just using Flutter/Dart.
• image_gallery_saver appears to have found a work around to this limitation, but it only works for certain file types. E.g. it won't work with audio files for some reason.
• downloads_path_provider same issue as bullet 1 and it is no longer maintained anyway.
• path_provider has a getExternalStorageDirectory() function. You'd assume it would return external storage options on Android, but all it currently returns are the application document directory (not accessible to users outside the app) and the temp application cache directory, which is impossible for a user to find without a tutorial.
• Just reference the path to emulated storage /storage/emulated/0/Download does not work Oct. 30, 2021. No permission to write even if you have been granted storage permission.

Flutter needs to be able to download files on Android to the Downloads or media directories. There are plenty of legit reasons that you might download a file from a Flutter app that needs to be accessible in external storage that is public and can easily be found through Android's Files app.

Anyway, what options does a Flutter dev have here Oct. 2021 to save files on Android to the Downloads directory??? Btw, just a default on iOS.

Right now, it appears on Android the best option for Flutter devs is to use a something like url_launcher and craft a url that forces a download, which will in turn access the browser's download manager. Is the best scenario for Android right now?

Finally, I love Flutter, but this particular area seems to be needing some love so Flutter devs don't fall behind other frameworks out there.

After saving the image in gallery using image_gallery_saver and permission_handler This is the result

error showing : I/flutter (24734): {filePath: null, errorMessage: java.io.FileNotFoundException: /storage/emulated/0/Pictures/1622347717438.jpg: open failed: EACCES (Permission denied), isSuccess: false}

problem : not saving screenshot of widget in gallery.

here is full code :

During the submission to Apple of the application I was notified of the following ITMS-90683: Missing Purpose String in Info.plist.

I want to upload my flutter app build to app store connect and test it through testflight.
But the App Store Connect sent me a mail that my app has problem.

The Two Problem:

I recently moved my projects to my M1 MacBook Pro. But I get the following error when running flutter run on iPhone 12 Pro Max Simulator.

I've been dealing with many problems for a few days. I updated the places I need to update in the pod file. I tried too mant methods to fix my errors. I try to delete my podfile update my podfile, i tried to pod update Firebase/Firestore.

Then i tried to this method to run my app : Run this commands

My save image method:
