You need to wrap your FloatingActionButton inside a Container and manage the size of the Icon with the size element:

     Align(
        alignment: Alignment.center,
        child: Container(
          width: 100,
          height: 200,
          child: FloatingActionButton(
            onPressed: null,
            child: Icon(
              Icons.share,
              size: 80,
            ),
          ),
        ),
      ),
