How run code after showDialog is dismissed in Flutter?

Question

How to update the Homepage just after the showDialog() is dismissed/disposed? Doesn\'t seem like it has an onDispose() function.

Noticed a couple of the above answers were a bit out of date due to the "child" construct used with the AlertDialog object being deprecated now.

Here is what I use now instead for a blocking alert dialog:

          showDialog(
            context: context,
            builder: (BuildContext context) {
              // return object of type Dialog
              return AlertDialog(
                title: new Text("Conversation Request"),
                content:
                    new Text("Have a conversation with this person"),
                actions: [
                  // usually buttons at the bottom of the dialog
                  new FlatButton(
                    child: new Text("Accept"),
                    onPressed: () {
                      performAccept();
                    },
                  ),
                  new FlatButton(
                    child: new Text("Ignore"),
                    onPressed: () {
                      performIgnore();
                    },
                  )
                ],
              );
            },
          )
