Path string returned by saveFile() on Android does not resolve to the actual selected file path

[lumpsoid]

Before creating an issue, make sure that you are on the latest file_picker version and that there aren't already any similar opened inssues. Also, check if it isn't described on the Wiki, specially on Troubleshooting page.

Also, sometimes a simple flutter clean and flutter build again with latest file_picker version, may end up by fixing cached issues, so I encourage you to first do so.

Describe the bug
This is reopening of the #1553, because bot closed it, but nobody looked into it.

When using the saveFile() method of the file picker, the returned string path is different from the actual picked file location. It will always be inside the Download folder.

Platform

• Android
• iOS
• Web
• Desktop

Platform OS version
14 (API 34)

How are you picking?

final now = DateTime.now();
final timeStamp = '${now.year}-${now.month}-${now.day}';
final fileName = 'export_$timeStamp.csv';
String? filePath = await FilePicker.platform.saveFile(
  dialogTitle: 'Select a folder to export data',
  fileName: fileName,
  initialDirectory: 'Download',
  bytes: Uint8List(
      0), //https://github.com/miguelpruivo/flutter_file_picker/issues/1523
);
if (filePath == null) return;
debugPrint(filePath);

Additional context
The android implementation of saveFile uses Environment.DIRECTORY_DOWNLOADS, so safeFile will always return the path to the downloads directory.

flutter_file_picker/android/src/main/java/com/mr/flutter/plugin/filepicker/FilePickerDelegate.java

Lines 91 to 92 in 8bbe066

	String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
	.getAbsolutePath() + File.separator + FileUtils.getFileName(uri, this.activity);

if nobody knows for now, how to resolve this issue, then as a hack, is it possible to use saveFile method without dialog?

I'd be curious if they couldn't just modify the file pick function since assumably it has to get the full path to the file to be able to either A) copy it to memory B) read the contents to memory or C) action on it? Saving is effectively the same just instead of returning just the full path you can manually set a file name, which that part works fine. Honestly even if actually saving the file doesn't work, i would think in most cases so long as you have the path+filename you should be able to write to it via other means

@deathblade666
it would be strange, because we can save data to the specified path, if used with bytes parameter, or is it like separate thing while you in dialog? and you can't just transfer this information back into the dart vm?

but probably there is some platform specific shenanigans

No stranger than if you were to pick a file, you'd just have to add additional actions to do what you want with it (dart io should be able to handle any file system actions provided a correct path).

Though, the primary issue here is that the returned path is incorrect, however the return path when picking a file (pickFiles()) is correct, so my thought is why not use the same logic for both. Since outside the bytes flag they are effectively doing the same thing, just one offers a "save as" dialog instead of a select file dialog.

issue still actual and there were no changes

after
flutter pub upgrade
and
flutter run
test app for this issue is still returning wrong picked path.
