I have a standard ElevatedButton action:

                    ElevatedButton(
                      onPressed: () => myPolicySet.serialize(),
                      child: const Text('serialize'),
                    ),

I also want it to navigate to a new page:

                    ElevatedButton(
                      onPressed: () {
                        Navigator.push(
                          context,
                          MaterialPageRoute(builder: (context) => const DiagramAppTwo()),
                      },
                      child: const Text('serialize'),
                    ),

Is this possible? if so, how should I do it?
