I need to save picture in a specific location flutter - flutter

Question

I need to save picture in a specific location rather than in temporary location.
void _takePicture(BuildContext context) async {
try {
await _initializeCameraControllerFuture;
final path =
join((await getTemporaryDirectory()).path, '${DateTime.now()}.png');
await _cameraController.takePicture(path);
Navigator.pop(context,path);
} catch (e) {
print(e);
}
}

You need to save the image into external storage directory for showing the image on gallery. Instead of getting temporary directory, obtain external storage directory.
final directory = await getExternalStorageDirectory();
You need to provide the permission on AndroidManifest.xml file of your android/app/src/main folder
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
then let's say that you want to create a folder named MyImages and add the new image to that folder,
final myImagePath = '${directory.path}/MyImages' ;
final myImgDir = await new Directory(myImagePath).create();
then write to the file to the path.
var kompresimg = new File("$myImagePath/image_$baru$rand.jpg")
..writeAsBytesSync(img.encodeJpg(gambarKecilx, quality: 95));
for getting the number of files, just obtain the files to a list and check the length of the list
var listOfFiles = await myImgDir.list(recursive: true).toList();
var count = countList.length;
Or check this.
