You can style ElevatedButton by using the styleFrom static method or the ButtonStyle class. The first one is more convenience than the second one.

Using styleFrom to style an ElevatedButton:

 child: ElevatedButton(
              onPressed: () {
                Navigator.pushNamed(context, 'register');
              },
              style: ElevatedButton.styleFrom(primary: Colors.green),
              child: const Text("Button")),

style: ElevatedButton.styleFrom(primary: Colors.red)
