dart - Copy image and save in the same directory - image

Question

I'm newbie in "flutter" and I have question.
It's possible to make copy of image and save it in device ?
File image;
picker() async {
print('Picker is called');
File img = await p.ImagePicker.pickImage(source: p.ImageSource.gallery);
if (img != null) {
image = img;
setState(() {});
}
}
save() async {
print('Save is called');
final Directory path = await image.parent;
setState(() {});
}
I have my image and I can get path of directory. But how to save this image in this directory but with another name ?
Let's say my picture is called x.jpg and I want to have the same picture saved as y.jpg without delete of x.jpg

Use simple_permissions plugin to get the permission to write to the external storage.
Use path_provider plugin to get the path to the external storage folder
Finally use the image plugin to write the image
sample code
Future<Io.File> saveImage(Io.File file) async {
try {
var dir = await getExternalStorageDirectory();
var testdir =
await new Io.Directory('${dir.path}/testfolder').create(recursive: true);
IM.Image image = IM.decodeImage(file.readAsBytesSync());
return new Io.File(
'${testdir.path}/${DateTime.now().toUtc().toIso8601String()}.png')
..writeAsBytesSync(IM.encodePng(image));
} catch (e) {
print(e);
return null;
}
}
also check the permission
void checkPer() async {
bool checkResult = await SimplePermissions.checkPermission(
Permission.WriteExternalStorage);
if (!checkResult) {
var status = await SimplePermissions.requestPermission(
Permission.WriteExternalStorage);
//print("permission request result is " + resReq.toString());
if (status == PermissionStatus.authorized) {
//saveimage
}
} else {
//saveimage
}
}
