try {
  if (!isCheck) {
    filePath = await downloadFile(filePath: "$filePath", url: url);
  }

await OpenDocument.openDocument(filePath: filePath);

} on OpenDocumentException catch (e) {
  debugPrint("ERROR: ${e.errorMessage}");
  filePath = 'Failed to get platform version.';
}

Future<String> downloadFile({String filePath, String url}) async {
    // CancelToken cancelToken = CancelToken();
  Dio dio = new Dio();
    await dio.download(
      url,
      filePath,
      onReceiveProgress: (count, total) {
        debugPrint('---Download----Rec: $count, Total: $total');
        setState(() {
          _platformVersion = ((count / total) * 100).toStringAsFixed(0) + "%";

Call preview screen

pushScreen() async {
  String name = await OpenDocument.getNameFolder();

    Navigator.of(context).push(
    MaterialPageRoute(
      builder: (context) => MyFilesScreen(filePath: name),
    ),
  );
}
