FileSystemException: Creation failed (OS Error: Not a directory, errno = 20)-CodePudding

I'm trying to convert a web page to pdf file. for that I've been using webcontent_converter to doing this task.

IconButton(
        onPressed: () async {
        var dir = await getApplicationDocumentsDirectory();
        var savedPath = (dir.path   "sample.pdf");
              var result = await WebcontentConverter.webUriToPdf(
                 uri:"https://xxxxxxx/xxxxxx/xxxxx",
                 savedPath: savedPath,
                 format: PaperFormat.a4,
                 margins:
                     PdfMargins.px(top: 35, bottom: 35, right: 35, left: 35),
                 );
                  await OpenFile.open(result);
                  WebcontentConverter.logger.info(result ?? '');
                  new Directory(result)
                      .create(recursive: true)
                      .then((Directory directory) async {
                    String path = directory.path;
                    File file;
                    file = await File(savedPath).create();
                    file.writeAsStringSync(path);
                  });
                },
                icon: Icon(Icons.save),
              ),

The pdf is not creating. I need to convert this WebView to pdf ad download it to download folder.

if there is any other package to do this. please suggest it as well

CodePudding user response：

result is not a path, it looks like it's some type of custom type. Log the return value of WebcontentConverter.webUriToPdf() and make sure it's a path. You will need to have the device's persistent storage path as well, this package can help: https://pub.dev/packages/path_provider

And a path should look something like this: /docs/anotherfolder/somefoldername/file.pdf

CodePudding user response：

Based on the error message, I think you need to add slash / before sample.pdf.

await getApplicationDocumentsDirectory(); return is like this (no slash at the end)

'/home/user/Documents'

So you need to add the slash /

var savedPath = (dir.path   "/sample.pdf");

or you can use join

var savedPath = join(dir.path, "sample.pdf");
