Thanks already. I stuck in this example for weeks.
in other examples mostly use apps own assets folder
I dont want to add file to asset folder.
I just want to get data from outside the app
and I want to assign this data to a variable
Filepicker package will solve the problem here is the link
You can access file name , path with this package

Is it always safe to use the path "/storage/emulated/0/{MY APP NAME}" to store the files ?
I Want to store files in the external storage of the android device and I want to store it in a folder named after the app name this folder needs to be located in the external storage.
Have you tried the package path_provider https://pub.dev/packages/path_provider/install?
It comes with the methods getExternalStorageDirectory() and getApplicationDocumentsDirectory() which might be what you are looking for. As far as I know different os types are automatically considered as well.
try the same package of ext_storage named android_external_storage its the same concept putting the downloaded data for example to the download folder.
Check this thread.
The directory an app can access on sdcard looks like /storage/1718-0217/Android/data/com.example.app_name/files. You can get this with the code below.
(await getExternalStorageDirectories())?[1].path;
One app should only access some restricted directories on sdcard. Or you should use Permission.manageExternalStorage.request(), it is strongly restricted and always return false.
Fortunately, per-app directories can also be scanned by other services such like media.
I've looked up many topic but none seems to do what i need.
I am working on a website with flutter and i need to read a file thats located on the server.
Is this in any way possible?
Edit: The contents in this file change, so i have to update the contents on the website.
If you want to be able to access the file as if it was locally stored, then it needs to be registered under your assets in your pubspec.yaml & should be included in the project itself. Otherwise, you will have to fetch the file using something like DIO to fetch it from wherever it is hosted.
I want to know if there is a way (with or without pubspec.yaml asset list) to read a directory where images will be stored, and create an array with all the paths to each image, so I can go through the array (say, with a FOR ) and create a gallery of photos. This with the purpose of being able to change, remove or add images from the directory without worrying about the paths being coded in assets.
I've read that I can use AssetBundle or RootBundle for this but I cant find any example doing so. Any help on this, even pointing me in a different approach, would be greatly appreciated.
Thanks!
EDIT: This got marked as a duplicate, but the question referenced as a duplicate is different in the sense that I need to scan a directory automatically , So I dont need to know any of the names of the files on the directory, I just want a way to read the directory (who's name I can know) and retrieve an array populated with the assets inside the directory.
There is (or at least used to be - beware, it's an implementation detail) an asset called AssetManifest.json. You can load that asset first, and it contains details of the actual assets.
I know about the path_provider package but it doesn't do what i want, or maybe I'm not just using it right. I read after so many trials and errors that the getApplicationDocumentsDirectory() returns a directory that is accessible only by the app itself, but what if i want to write to a phone's local document directory or so and be able to view the file in my file explorer later on?
If you want to save where the file explorer reaches, you must use the method getExternalStorageDirectory(). It only works in Android and you'll need READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions.
Actually, you're able to find the files saved using getApplicationDocumentsDirectory() and getTemporaryDirectory() as well, but you'd need root access.
In my project, I have a bunch of items stored as assetBundles. In my server, I stored a list of item including their id and version. So ideally, using UnityWebRequest.GetAssetBundle(uri, versionId)I just get the item lists every time I open the app, if first opened, it will download every item; if secondly open, it will only download the one I have updated the version number on the server. Everything is very easy.
But now, I want to store those assetBundles at local first so that people don't need to download with cellular data.Is there an easy way to manage those assetBundles?
You can place the AssetBundles in the StreamingAssets folder. This is what the folder should look like:
Assets/StreamingAssets/
When you build the project, Unity will include the AssetBundles in the build. Of-course, you can use the Resources API but the StreamingAssets folder seems to be more appropriate here.
Once you place the AssetBundles there, you can use Application.streamingAssetsPath and AssetBundle.LoadFromFile to load the AssetBundle.
You can also use the WWW API with Application.streamingAssetsPath to load the AssetBundle.
You 'dont' keep a local text file. you have the version number inside the local bundle. You have a text file on the server. then get the text file, compare that with the version in the bundle and update if necessary.
In the server, you can have an assetbundle with only a textasset to secure that too.
you can build the asset bundles and have them in the streamingAssets folder or anywhere and use AssetBundle.LoadFromFile()
