Creating a Custom AppBar in Flutter with Swift Theme

In Flutter, you can easily create a custom AppBar for your application. In this tutorial, we will explore how to create a custom AppBar with a Swift theme.

Prerequisites

To follow along with this tutorial, you should have basic knowledge of Flutter and Dart programming language.

Step 1: Create a New Flutter Project

Start by creating a new Flutter project using the following command in your terminal:

flutter create custom_appbar
cd custom_appbar
Step 2: Update pubspec.yaml

Open the pubspec.yaml file and add the flutter_svg package dependency:

dependencies:
  flutter:
    sdk: flutter
  flutter_svg: ^0.22.0

Save the changes and run flutter pub get in your terminal to download the dependencies.

Step 3: Update main.dart

Open the lib/main.dart file and update the code as follows:

import 'package:flutter/material.dart';
import 'package:flutter_svg/flutter_svg.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Custom AppBar',
      theme: ThemeData(
        primarySwatch: Colors.deepPurple,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Row(
            children: [
              SvgPicture.asset(
                'assets/swift_logo.svg',
                height: 30,
                width: 30,
              ),
              SizedBox(width: 10),
              Text('Custom AppBar with Swift Theme'),
            ],
          ),
        ),
        body: Center(child: Text('Welcome to Custom AppBar')),
      ),
    );
  }
}
Step 4: Add Swift Logo SVG

Place your custom Swift logo SVG file in the assets folder (create one if it doesn't exist). The SVG file can be downloaded from any trusted source or created using a vector graphics editor.

Step 5: Update pubspec.yaml

Open the pubspec.yaml file and add the following lines to include the assets:

flutter:
  assets:
    - assets/
Step 6: Run the App

Save the changes and run the app using the following command:

flutter run

You should now see a custom AppBar with the Swift logo in your application.
