I use Electron to build my app.
I want to load data from zip unpack it to folder file and show it to user.
I decompress data and then open window since its html it should work fine.
However i see that app.getAppPath() on dev mode is giving me example path D:\elektron but when i build up path is different D:elektron\resources\app how to solve this ?

Hi forgive my English and also a newbie on flutter iOS, I have an app on flutter on iOS that users can take pictures and videos from their camera and gallery I'm using the image_picker package this has no problem, then I save it on the on its Application Documents Directory I tried following this guide
my code for getting the application directory is this
Directory _appDocDir;
_appDocDir = await getApplicationDocumentsDirectory();
final Directory _appMediaDir = Directory('${_appDocDir.path}/Pictures/');
return _appMediaDir;
added with a 'Pictures' directory this will give a path of
/Users/macman/Library/Developer/CoreSimulator/Devices/96060868-7E5C-4E15-9900-4D1D4B0B5ACE/data/Containers/Data/Application/BE7728A6-FF15-498E-91A0-A96A3DDE5B31/Documents/Pictures/D_IMG_0002.JPG
from the iOS-simulator I save it and put in the database, and after re-compiling the app or doing a build update the previewing the image/video path is not found anymore. I tried to save another image on this build it and gave this path
/Users/macman/Library/Developer/CoreSimulator/Devices/96060868-7E5C-4E15-9900-4D1D4B0B5ACE/data/Containers/Data/Application/9D634D91-07B8-43BE-8646-2A55833322DF/Documents/Pictures/D_IMG_0005.JPG
I noticed earlier path this part "/BE7728A6-FF15-498E-91A0-A96A3DDE5B31/" is changed every time I re-compile the app or make an update from the iOS device the image is not found. What is the most practice for this users able to save image am I doing it wrong?
Update: I tried changing my logic to change the saved path to only the base name (D_IMAGE_0005.JPG) then when previewing the image will call the current application documents directory but this does not work also.
Thank You
Hi don't save the whole path given by the getApplicationDocumentsDirectory() on you record, instead save only the basename, and every time you preview/load the image call the
getApplicationDocumentsDirectory() + 'Pictures/<basename>',
every time the app gets updated or recompiled on the iOS the appid changes, that is why your path fails to load on a recompile.
iOS removes the documents directory every time you reinstall the app if your application is running on a sandbox environment.
Please refer to this stackoverflow question for more clarification
In a Flutter app I have a dart file located at FlutterTest\sandbox\lib\my_widget\my_widget.dart.
And I have an image located at FlutterTest\sandbox\lib\my_widget\imgs\myImage.png.
From my_widget.dart how can I point a file to this image, something along the lines of new File("???\my_widget\myImage.png")?
Just to clarify, in Java I could do something like MyClass.class.getResource("myImage.png").toString().
By the way if I print(Directory.current.path) it gives me simply /. And if I try to list the contents of this directory it tells me: "Directory listing failed, path = '/' (OS Error: Permission denied, errno = 13)". So I don't actually know where the current directory is.
You can directly access the file system but due to differences in android and iOS you'll probably end up using the path provider plugin. Also, see this flutter cookbook as they call it.
But if all you're trying to do is access a file from your build, you'll want to define it as an asset in your pubspec, and then access it using Flutter's AssetBundle (or Image.asset) rather than directly using File or Image.file. See the flutter documentation on assets.
I have a data file that I need to include with my app when I distribute it. When loading any files in the app, I prefix the file name with:
Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
This works great for anything I create within the app (and for reading back), like files I download in response to a user action. But I can't for the life of me figure out how to place files there when I build my app in Visual Studio.
I've tried making a "Documents" subdirectory in the special "Resources" folder, but that didn't work (I tried setting the "Build Action" to both BundleResource and Content). When I look at the folder for my app (from using the simulator) I can see that in the "Documents" folder there's all the files I downloaded, but I can't find my data file that I'm trying to bundle ahead of time. I even searched my entire hard drive on the Mac and still couldn't find said data file.
The data file isn't an image, if it matters. Just raw binary data. How do I set it up so that this file goes into the proper documents directory at compile time, so that I can read it using the SpecialFolder.MyDocuments prefix? Thanks.
You can't. You can include files in your app bundle, and then at startup copy them from the bundle into a user folder. But this won't happen automatically.
I have a file uploader for users to store images, which I'm saving content to a folder within the application data directory (app.getPath('userData')). This all works fine.
When I attempt to load the image using a basic image tag, with the src pointing to the correct location within the application data directory, it fails to render.
This only occurs after I've packaged the app using electron-forge (make & package). I've only attempted to make for OS-X (darwin x-64). I'm guessing it has something to do with asar, but I can't seem to get this working. I've attempted to use the file protocol for the image source too.
Any idea how to correctly do this?
I found the easiest way is to serve all content up from a server bound to localhost
I have four files (config.xml, index.html, scripts.js, and styles.css). The html has a canvas and a form for users input. I want to run on blackberry simulator (Torch version 6...). I create a zip file of all those files. Then create a bin folder. Now when I run the simulator and load the application, I have either blanc screen, either the following error: Resource does not exist.
Here is the config file code:
BlackberryTest
I had the same problem. You need to use local:/// prefix before the name of the local resource to access it.
