save a temp file from path-provider to download file Android/IOS in flutter

[Samer Jallad]

Hi everyone,

I have a question, I am using Path-provider to generate a path for a new generated PDF file from my App… but path provider is storing the file in the App folder & after closing the app the file will be deleted, I am using ```getExternalStorageDirectory```… how can I save that file to downloads when selected.Anybody can help me?

just small explanation... the PDF file will be viewed from the App using

flutter_full_pdf_viewer

then from that page I need to let the user select if he wants to save the file or close the hall file.

This is the code for the file save

``` Future savePdf({name, pdf}) async {
  try {
    final dir = await getExternalStorageDirectory();
    String documentPath = dir.path;
    fullPath = "$documentPath/$fileName";
    final file = File('$fullPath');
    await file.writeAsBytes(await pdf.save());
    print('XXXXXXXXX$fileName');
    return file;
  } catch (e) {
    // print('we have a problem');
  }
  print(fullPath);
}

```

And this is the PDFViewer page code

``` @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        child: PDFViewerScaffold(
          appBar: AppBar(
            title: Text('PDF page'),
            actions: <Widget>[
              IconButton(
                icon: Icon(Icons.share),
                onPressed: () {
                  Share.shareFiles(
                    ['$path'],
                  );
                  print('iiiiiiiiiiiiii$path');
                },
              ),
              IconButton(
                icon: Icon(Icons.save),
                onPressed: () {},
              ),
            ],
          ),
          path: path,
        ),
      ),
    );
  }
}

```
