How to Add Multiple Floating Action Buttons in One Screen in Flutter App

The attribute'floatingActionButton' of Scaffold() widget allows you to add only one floating action button, but if you do a simple trick, you can achieve a single screen with multiple floating action buttons like below:

Add Multiple Floating Action Buttons in Scaffold() widget:

Scaffold(
  floatingActionButton: Wrap( //will break to another line on overflow
    direction: Axis.horizontal, //use vertical to show  on vertical axis
    children: <Widget>[
          Container( 
            margin:EdgeInsets.all(10),
            child: FloatingActionButton(
              onPressed: (){
                  //action code for button 1
              },
              child: Icon(Icons.add),
            )
          ), //button first

          Container( 
            margin:EdgeInsets.all(10),
            child: FloatingActionButton(
              onPressed: (){
                  //action code for button 2
              },
              backgroundColor: Colors.deepPurpleAccent,
              child: Icon(Icons.add),
            )
          ), // button second

          Container(
            margin:EdgeInsets.all(10),
            child: FloatingActionButton(
              onPressed: (){
                  //action code for button 3
              },
              backgroundColor: Colors.deepOrangeAccent,
              child: Icon(Icons.add),
            )
          ), // button third

          // Add more buttons here
    ],),
)
