Flutter | How can I change my FloatingActionButton background color to transparent?-CodePudding

Im completely new in flutter and programming btw and I have a question, how can I change my floatingActionButton color Icon from lightBlueAccent to gradient? Here is my code:

floatingActionButton: FloatingActionButton(
        backgroundColor: Colors.lightBlueAccent,
        onPressed: () {
          FirebaseFirestore.instance.collection('categories').add(
            {
              'title': controller.text,
            },
          );
          controller.clear();
        },
        child: const Icon(Icons.add_circle_rounded),
      ),
