Future as a parameter with async in flutter

FloatingActionButton(
  onPressed: () => getImageFromCam(index),
  tooltip: 'Pick Image',
  child: Icon(Icons.add_a_photo),
);

...

Future<void> getImageFromCam(int index) async {

  final image = await ImagePicker.pickImage(source: ImageSource.camera);
  setState(() => _image = image);
}
