Display Floating Action Button in Flutter

A floating action button (FAB) is a circular button that contains an icon in the center. FAB is used to perform the primary action on a screen. Recommend to use a single FAB per screen and for positive actions such as "add", "send", "call", etc.

FAB can be created using FloatingActionButton class. It usually used with the Scaffold.floatingActionButton property.

import 'package:flutter/material.dart';

void main() => runApp(const MaterialApp(home: MyApp()));

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  State<MyApp> createState() => _MyAppState();

class _MyAppState extends State<MyApp> {
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(title: const Text('Floating action button')),
        floatingActionButton: FloatingActionButton(
          child: const Icon(Icons.add),
          onPressed: () {
