    await Directory(firstPath).create(recursive: true);

As path_provider doesn't provide download directory path. You will need to call native apis.

Use These packages to do that:-

downloads_path_provider OR ext_storage

In case of 1st one the code will look like this:-

var documentDirectory = await DownloadsPathProvider.downloadsDirectory;

In case of 2nd one the code will look like this:-

var documentDirectory = await ExtStorage.getExternalStoragePublicDirectory(ExtStorage.DIRECTORY_DOWNLOADS);
