Let’s start by creating a new project or you can also choose exiting project

flutter create appbar
cd appbar

once we created a new project, we can start working with lib/main.dart file

Flutter AppBar Example

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: Scaffold(
      appBar: AppBar(
        title: Text("CODESUNDAR"),
        leading: Icon(Icons.menu),
        backgroundColor: Colors.redAccent,
        actions: <Widget>[
          IconButton(icon: Icon(Icons.videocam), onPressed: () => { }),
          IconButton(icon: Icon(Icons.account_circle), onPressed: () => { })
        ]
      )
    ));
  }
}

Explanation: We have created a stateless widget (because we’re not going to handle any data at this moment).

• We have implemented material design with MaterialApp, which needs Scaffold (is nothing but a single page/view).
• Scaffold widget contains more parameters but for now, we only need appBar
• Inside AppBar widget we have passed title: as a Text widget
• We have set backgroundColor using Colors objects (you can choose any colors)
• The leading parameter allows you to put any widget as the left side (front slot) where actions are the right side.
• Now, we have created IconButton inside actions

The final output for flutter AppBar
