I want to get gallery folder path.
I tried to use multiple libraries [path_provider, storage_path, image_save, multi_image_picker ...] to get the gallery folder path, but none of the libraries got the gallery folder path.
See, I don't find any great thing to save your file to your gallery, what I did found is to how to get your things done.
My solution will give you some things like
Save a file visible to the user
Check whether the file exists or not
Saving the file:
For saving the file we can rely on the package downloads_path_provider.
Look at this answer for using this package precisely
Flutter save file visible to the user - StackOverFlow would help you to know how he is using path_provider package to save his files.
Check whether the file exists or not
To do this, you can use this code inside your code, where you are trying to save the file, form the above answer.
Important: You will get the path of the file where you are storing the file, just pass the path in the below code
import 'dart:io' as io;
// for a file
bool exists = io.File(path).exists();
// for a directory
bool exists = io.Directory(path).exists();
if(exists) // do your operation
else // do your else operation
I am able to produce this much content for your problem. Any feedback are welcomed.

With file_picker, I can't get file's real path or URI from FilePicker.platform.pickFiles(). It only returned something like this
/data/user/0/my_app_dir/cache/file_picker/file
and logged this
I/FilePickerUtils(27005): Caching from URI: content://com.android.providers.media.documents/document/video%3A1519
D/FilePickerUtils(27005): File loaded and cached
at:/data/user/0/my_app_dir/cache/file_picker/file
D/FilePickerDelegate(27005): File path:[com.mr.flutter.plugin.filepicker.FileInfo#705d9ef]
That's not what I want. I just want the real original absolute file path, the file information, regardless of what I'll going to do with the file. So I'm looking for a package that do that or the solution how to manually pick file and get the file path like I could do natively. Thank you in advance.
It's not impossible with native code. It's just package publisher who made it unavailable using it. Follow this to implement file path picker on native code. It works for me.
I'm a beginner at flutter and dart and had some issues with file handling using flutter.
I'm trying to store data locally in text files for my flutter application, and came across the standard tutorial on flutter's website which used path_provider and dart:io. It had instructions on getting the path and reading and writing to a file, however this didn't seem to work for files I added to the project. The only way to store to files was to first write using the inbuilt functions, then reading this newly created file. I can't add my own file and read it using flutter.
I also can't open the file created by flutter as I don't know where its stored. The path given by getApplicationDocumentsDirectory() returns the path /data/user/0/com.example.daily_challenges/app_flutter, and I don't know where to find this in my project.
In summary: How do I read a pre-existing file and how do I view the file created automatically by flutter.
Thanks :)
You can access the files from a physical device or simulator through Device File Explorer in Android Studio. Follow this guide
You won't be able to access getApplicationDocumentsDirectory().
If you are using android device, you can try to store it in getExternalStorageDirectory(). There's no equivalent in IOS though.
If you are running in a physical device. Open Device File Explorer in Android Studio and you can find the file under
data/data/your app package/app_flutter/fileName.txt
For example,
data/data/com.example.file_example/app_flutter/example.txt
And if you want to read the pre-existing file, you not need to anything specific, if you give the same file name, if not exist, it will create one, otherwise it will return the old one.
final File file = File(filePath);
file.writeAsStringSync('${text}', mode: FileMode.append);
For write, you consider using FileMode if you want to append text to the existing file. Or else by default overwrite will happen.
For read, you can consider this
final File file = File(filePath);
String text = await file.readAsString();
Just use Device File Explorer from Android Studio.
But the weird thing, path_provider gives you path like /data/user/0/your_app_id/..., but in fact all files are located in /data/data/your_app_id/..., as mentioned in previous answer.
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 am using 'tess4j' api to get the text from a .jpg image.
The 'TessData' folder is packaged in the jar files. I want to include custom fonts and create my own 'TessData' folder, is there a way we can give 'TessData' location during run time.
I used the below method and it didn't pick up the TessData from custom location.
TessAPI1.TessBaseAPIInit3(handle, "C:\1. tesseract folder\bodoni mt\TrainData", lang);
Please let me know if we can do so.
That does not look like a valid string. Anyway, if tessdata is inside a JAR file, you'll need to extract it and specify the location in the Init method.
Yesterday I found this great looking plugin for file and image management for tinymce however I cannot get the files to actually save to the drive. I have tried every commbination I can think of.
responsivefilemanager.com - This plugin.
Anyone used it before and know of the settings I might need?
The plugin sits here: /public_html/cms/app/webroot/js/tinymce/plugins/filemanager
I'm trying to set it up so the uploads go here: /public_html/cms/app/webroot/files/cms
The config file for the plugin has 3 lines to configure for this, these are as follows and as I have set them up:
$base_url="http://domain.com/cms/"; // base url of site. If you prefer relative urls leave empty
$upload_dir = 'app/webroot/files/cms/'; // path from base_url to base of upload folder
$current_path = '../../../files/cms/'; // relative path from filemanager folder to upload folder
Now when I started working this out I would get an error for the plugin saying the root folder doesn't exist so I keep playing with the paths and now I don't get this error but I still cannnot get it to upload the images, everything looks like it works, I get the preview as the image is uploading and a green tick once it's complete then I go back to the files list and the image isn't there. It's not on the server either. I'm wondering if there is a way to debug this and work out what's happening?
Thanks
I ended up getting this to work with the following settings:
$base_url="http://domain.com"; // base url of site.
$upload_dir = '/cms/app/webroot/files/cms/'; // path from base_url to base of upload folder
$current_path = '../../../../files/cms/'; // relative path from filemanager folder to upload folder
Thanks
Try the following settings if you still have not got this sorted out yet:
$base_url="http://www.domain.com/cms"; // base url of site. If you prefer relative urls leave empty --> No trailing slash
// The upload directory will be a dir you have created for the files to be uploaded to, ie: localhost/cms/app/webroot/files/cms --> this file must have write permission.
$upload_dir = '/app/webroot/files/cms/'; // path from base_url to base of upload folder --> write permission (chmod = 755)
$current_path = '../../../../files/cms/'; // relative path from filemanager folder to upload folder (you are missing one "../")
// The thumbs folder located in tinymce/plugins/filemanager/thumbs must also have write permission (chmod = 755)
That should do it
use gsynuhimgupload plugin TinyMCE
http://gsynuh.com/tinymce-simple-image-uploader/136
TinyMCE simple image uploader
Here’s a repost of my TinyMCE image uploader plugin. It used to be on gsynuh-labs.com (but I let this domain go).
please note that this plugin is no longer supported by me – and I’m not responsible for any inconvenience caused by it, it is shared “as-is” and you have to be responsible when using it ie: take care of any possible injection problems/security problems in your own site’s context.
I’m not interested in expanding it myself as I was only looking for a very minimal image uploading plugin for myself but If you are going to expand on it, I can list your version on this page if you want, just contact me.
