Custom button with FAB style

Question

I want to make a set of buttons with the ripple effect, elevation and shape like a FAB button. I read that I can only use one FAB button per screen, so I need to create my owns instead of using a set of FAB buttons.

How can I achieve the effect? It's possible to modify the FAB code to this?

Answer 1

So if you want the fabs in a vertical order wrap them in a Column like this

class RandomFabScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      floatingActionButton: Column(
        mainAxisSize: MainAxisSize.min,
        children: <Widget>[
          FloatingActionButton(
            child: Icon(Icons.home, color: Colors.white,),
            onPressed: (){},
            backgroundColor: Colors.cyan,
          ),
          SizedBox(height: 10,),
          FloatingActionButton(
            child: Icon(Icons.playlist_play, color: Colors.white,),
            onPressed: (){},
            backgroundColor: Colors.red,
          ),
          SizedBox(height: 10,),
          FloatingActionButton(
            child: Icon(Icons.person, color: Colors.white,),
            backgroundColor: Colors.yellow,
            onPressed: (){},
          ),
          SizedBox(height: 10,),
          FloatingActionButton(
            child: Icon(Icons.warning, color: Colors.white,),
            onPressed: (){},
            backgroundColor: Colors.blue,
          ),
        ],
      ),
    );
  }
}

The output:

And if you want them in the horizontal order, wrap them in a Row

like this

class RandomFabScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      floatingActionButton: Row(
        mainAxisSize: MainAxisSize.min,
        children: <Widget>[
          FloatingActionButton(
            child: Icon(Icons.home, color: Colors.white,),
            onPressed: (){},
            backgroundColor: Colors.cyan,
          ),
          SizedBox(width: 10,),
          FloatingActionButton(
            child: Icon(Icons.playlist_play, color: Colors.white,),
            onPressed: (){},
            backgroundColor: Colors.red,
          ),
          SizedBox(width: 10,),
          FloatingActionButton(
            child: Icon(Icons.person, color: Colors.white,),
            backgroundColor: Colors.yellow,
            onPressed: (){},
          ),
          SizedBox(width: 10,),
          FloatingActionButton(
            child: Icon(Icons.warning, color: Colors.white,),
            onPressed: (){},
            backgroundColor: Colors.blue,
          ),
        ],
      ),
    );
  }
}

You can use Row to wrap FloatingActionButton

code snippet

Row(
                mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                children: <Widget>[
                  FloatingActionButton(
                    onPressed: () {
                      print("click 1");
                    },
                    child: Icon(Icons.navigation),
                    backgroundColor: Colors.green,
                  ),
                  FloatingActionButton(
                    onPressed: () {
                      print("click 2");
                    },
                    child: Icon(Icons.event),
                    backgroundColor: Colors.red,
                  ),
                  FloatingActionButton(
                    onPressed: () {
                      print("click 3");
                    },
                    child: Icon(Icons.gradient),
                    backgroundColor: Colors.yellow,
                  ),
                  FloatingActionButton(
                    onPressed: () {
                      print("click 4");
                    },
                    child: Icon(Icons.album),
                    backgroundColor: Colors.blue,
                  ),
                ]),
