Floating action button: how to change the splash color and highlight color like in a RaisedButton?

Question

I see that the splash and highlight colors that the FAB takes are connected to argument color in the MaterialApp widget. is there a way to override those colors? I found only foreground color and background colors and those are not what I want. Thanks

If you check the source code of FloatingActionButton the splash color is tied to the Theme of the app, so you can change the theme only for the button, like this:

Theme(
  data: Theme.of(context).copyWith(highlightColor: Colors.yellow),
  child: FloatingActionButton(
    backgroundColor: Colors.red,
    onPressed: () {},
    child: Text("hello world"),
 ),
)
