Question

I am actually trying to convert an image picked by ImagePicker in flutter to base64 image. I am always getting the error.

FileSyst         


        

Answer 1

hi I just changed my code as follows,

List<int> 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<int> imageBytes = await widget.fileData.readAsBytes();

Answer 2

you can simply change the image to string :

final bytes = Io.File(imageBytes.path).readAsBytesSync();

String img64 = base64Encode(bytes);
