When accessing files from your PC your are actually enumerating the MediaStorage database for files. Its not pulling a traditional directory lists. So what you see is based on what is in that database and the path entries in the database. Usually the easiest way to fix the problem is to just clear the MediaStore databases to get the bad entries out of the MediaStore Database and let the system reindex the files and put into the database with the proper paths.
When you are done the files should show up with proper directory tree and be visible from the PC. Depending on amount of files on the phone it can take as minutes to rebuild the media database as the service walks the phone directories, getting meta data, creating thumbnails, etc.
Android recommends that you call Environment. So you use the below code. Here you can use a finder-like structure. There open each picture one by one, go on setting three dots.. It will show up in the android file 'Pictures' from where you can also copy them by using your explorer. There is no 'save all' function, however so it must be done one by one, but it works.

To access a file in storage, the app needs to have the permission to read storage. Otherwise the user will get a permission error unless the file is located in the app's directory. First, add the package in the dependencies section of pubspec. After running flutter pub get or click on 'Packages get' in Android Studio , the package can be used by adding this import statement.
The basic usage only requires you to pass an argument which is an instance of File. In addition, you are not allowed to pass null value for scale and repeat arguments just keep the default value if you don't want to set it. Below is a basic example that only passes the file argument. No size constraints applied to the widget and the actual size of the used image the width is bigger than the available space.
As you can see from the output, the default behavior is the image is scaled down so that it can fit in the available space. The next examples in this tutorial show you how to customize how the image should be rendered.
You can set the width and the height of the loaded image by passing width and height named arguments respectively. If you set the image to be a specified size, sometimes the image may not fit in the available space. In that case, you may need to set how the image should be inscribed to the space. To do so, pass a BoxFit enum value as fit argument. We have a post about FittedBox which shows the differences between the BoxFit enum values.
The below example uses BoxFit. October 4, at am. Shailesh Vishwase says:. August 18, at am. MuayinKei says:. June 19, at am. Panneer says:. July 4, at pm. September 30, at pm. Meghana Shetty says:. December 4, at am. Harish says:. July 11, at am. May 14, at am. Omkar Mahadik says:.

It is hard work when you built your entire app, then find out after targeting 25 all of your camera methods break. This works for me until I get time to do it the right way. Works on Android 7.

That being said, my guess is that you will still get this exception. I suspect that they are just checking the scheme and are not trying to determine if the file truly is world-readable.
You could create a custom strategy for my StreamProvider , or roll your own ContentProvider , to get past the problem. Still thinking how I'm going to solve this.. The app I am updating with Android N support is a root browser. But now you can't open any files anymore in root directories. For example, users who work in split-screen mode or on freeform multi-window devices Chromebooks, Samsung DeX will be told that your app may not work with multi-window.
Whether that is important or not is up to you. Show 13 more comments. Karn Patel Karn Patel 3 3 silver badges 13 13 bronze badges. Thank you for this. I also want to let you know that there is a better way to get the file extension. There are options for internal storage vs. I was getting the following exception: java.

I wish I'd seen this first. I didn't prove it worked for me, but it's so much less cumbersome than FileProvider. This does not get exception, but it can't send the file to the related app either. So, not worked for me. This will fail on Android 10 and higher, as you cannot assume that the other app has access to external storage via the filesystem.
