Close modal bottom sheet programmatically in flutter

Closing a ModalBottomSheet programmatically is done via

Navigator.pop(context);

So I just call that pop function inside the onTap callback function of the GestureDetector.

showModalBottomSheet(context: context, builder: (BuildContext context)
{
  return SingleChildScrollView(child:
    Column(crossAxisAlignment: CrossAxisAlignment.stretch, children: [
      GestureDetector(onTap: () {
          Navigator.pop(context);
          doSomething();
        }, child:
        Text("Item 1")
      ),
      GestureDetector(onTap: () {
          Navigator.pop(context);
          doSomething();
        }, child:
        Text("Item 2")
      ),
    ]),
  );
});
