hi I just changed my code as follows,

List imageBytes = widget.fileData.readAsBytesSync();
print(imageBytes);
String base64Image = base64Encode(imageBytes);

and this is working fine now.

It is better to read it asynchronously as the image can be very large which may cause blocking of main thread

 List imageBytes = await widget.fileData.readAsBytes();
