[cross_file] Flutter app opened from runner debug directory or release directory does not save the files

[arnoldmitrica]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

The issue is fully explained here: https://stackoverflow.com/questions/76649510/flutter-windows-app-from-windows-runner-does-not-save-the-new-file-to-a-path-in

Saving a file actually works when the app is started by flutter command either by flutter run or flutter run --release -d windows.

Expected results

It saves the file to the path specified as it works in debug mode

Actual results

Does not do anything, does not throw any error/exception

Code sample

Code sample

void funcExample({required String choseName, required String chosenPath, required UInt8List fileAsBytes,}) {
     final docx = await DocxTemplate.fromBytes(fileAsBytes);

     final docxGeneratedBytes = await someMethodThatChangesDocx(docx);

     final path = "$chosenPath\\$chosenName.docx";
  
     final XFile fileToBeSaved =
     XFile.fromData(Uint8List.fromList(docxGeneratedBytes),name: chosenName);
     await fileToBeSaved.saveTo(path);
}

Hi @arnoldmitrica
In order to address the issue properly, please provide a completed and minimal reproducible code sample that doesn’t include 3rd party plugins or complex production code so that we may verify this. Thanks!

[arnoldmitrica]

I am back with the fix, Managed to see that by creating the File object should be done in a different way for release:
if (kReleaseMode) {
file = File('data\flutter_assets\lib\assets\$templateName.docx');
} else {
file = File('lib/assets/$templateName.docx');
}
