How to change the size of FloatingActionButton?

Question

I'm trying to set a size to a FloatingActionButton in flutter, I wanna set width/height, I mean, make the button bigger, I was looking for a circular button, but the only one that I got was this one, so, I started to work with this, but I need it a little bigger.

Use a Container where you can specify width and height, then use a RawMaterialButton, like this:

final myFabButton = Container(
  width: 200.0,
  height: 200.0,
  child: new RawMaterialButton(
    shape: new CircleBorder(),
    elevation: 0.0,
    child: Icon(
      Icons.favorite,
      color: Colors.blue,
    ),
    onPressed: () {},
  ),
);
