Saving files

[ialameh]

I have an issue,
I am getting the path using getExternalStorageDirectory
I have a file in an asset directory (as a template), I am reading that file

Future<ex.Excel> loadExcel(
      {@required String sheet, @required String fileName, bool isAsset = false}) async {
    File file = File(fileName);
    ByteData data;
    if (isAsset == true) {
       data = await rootBundle.load(fileName);}
      else { 
        print("arrived to read filename $fileName");
        data = file.readAsBytesSync().buffer.asByteData();
        }
    var bytes = data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);
    ex.Excel excel = ex.Excel.decodeBytes(bytes, update: true);
    return excel;
  }

I use rootBundle.load is from the asset and using file if it is from the app directory (through the path)

saving got no issue, using 

Future<void> saveExcelSheet(
      {@required ex.Excel excel, @required String fileName}) async {
    String dir = await getPath();
    if (await Permission.storage.request().isGranted) {
      excel.encode().then((onValue) async {
        File file = File("$dir/$fileName");
          file.createSync(recursive: true);
          file.writeAsBytesSync(onValue);
      });
    } else {
      print('permission not granted');
    }
  }
}

what I am facing, is if I initiate the file (copy it to the app directory) and try to read it immediatly, I get file not found error, even though the file exist

I thought it might be that the file needs to be closed, but I could not figure it out how to close the file.,

Any ideas?

excel.encode().then((onValue) async {
        File file = File("$dir/$fileName");
          file.createSync(recursive: true);
          file.writeAsBytesSync(onValue);
      }).then((_){
      // try to read it here 
      });

That is interesting, thank you, I will try it.

I sort out my problem when I found I was making unnecessary multiple reads for the file.

I can thank you enough for the great package, I will make another donation as soon as possible, I urge everyone who use this to donate.

Thanks again
