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.
To follow along with this tutorial, you should have basic knowledge of Flutter and Dart programming language.
Start by creating a new Flutter project using the following command in your terminal:
flutter create custom_appbar
cd custom_appbar
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.
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')),
),
);
}
}
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.
pubspec.yaml
Open the pubspec.yaml
file and add the following lines to include the assets:
flutter:
assets:
- assets/
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.
In this tutorial, we have learned how to create a custom AppBar with a Swift theme in Flutter. This can be useful when designing unique and branded UI elements for your application.
