You could wrap your Switch inside a Transform widget and change the scale.

        Transform.scale( scale: 2.0,
                          child: new Switch(
                            value: true,
                            onChanged: (bool value1) {},
                          ),
                        )

Scale = 1 is the default size , 0.5 half size , 2.0 double size, you can play with the values :)
