How can I show a splash or some indication when the button is pressed for an elevated button.

Here is the code snippet:

 ElevatedButton(
                                                                      style:
                                                                          ButtonStyle(
                                                                        overlayColor: WidgetStateProperty.all(const Color
                                                                            .fromARGB(
                                                                            255,
                                                                            16,
                                                                            99,
                                                                            167)),
                                                                        splashFactory:

                                                                        backgroundColor:

                                                                        ),
                                                                      ),

                                                                                userData.selfRef,
                                                                            planRef: pricePlans.first.selfRef);
                                                                      },
                                                                      child:
                                                                          Text(
                                                                        'Checkout',

                                                                                17,
                                                                            color:
                                                                                Theme.of(context).colorScheme.onPrimary),
                                                                      )),

I used the splashFactory but it is not doing anything.
