How to solve "Invalid image data" error in Flutter

Question

I'm using SQLite for storing data locally. insert an image as a string and get them to show here is the error that occurs _Exception (Exception: Invalid image data).

Encode image code:

Future pickImage(ImageSource source) async {
final image = await ImagePicker().pickImage(source: source);
if (image == null) return;
final imagePermanent = File(image.path);
setState(() => _image = imagePermanent);
imageData = base64Encode(_image!.readAsBytesSync());
print(imageData);
return imageData;}

Decode image in display page:

showImage(String image) {
    return Image.memory(base64Decode (image) );
}

Display in code:

showImage(widget.euser.image.toString()),

Error Shows :

Exception has occurred._Exception (Exception: **Invalid image data**)

Console logs show like this:
