This is even simpler. Tried it. Create the FloatingActionButton as a separate Stateless Widget. Call this Stateless Widget from the Scaffold.

class Abc extends StatelessWidget
{
   Widget build(BuildContext context)
   {
      return Scaffold(
         appBar:AppBar(title:Text("Long List View")),
         body:SomeOtherWidget(),
         floatingActionButton:MyFAB()  
      );
   }
}

class MyFAB extends StatelessWidget
{
    Widget build(BuildContext context)
    {
       return FloatingActionButton(
            onPressed:(){
                showSnackBarHandler(context);
            },
            child:Icon(Icons.add),
            tooltip:"Press to Add More"
       );
    }
}

void showSnackBarHandler(BuildContext context){

var snackBar = SnackBar(
    content:Text("Hello")
);

Scaffold.of(context).showSnackBar(snackBar);

}
