Flutter is not limited to mobile app development; you can also use it to build web applications. In this tutorial, we'll explore how to get started with Flutter for web development and create a simple web app.
Prerequisites
Before you begin, make sure you have the following installed:
Flutter: Install Flutter on your machine by following the instructions in the official Flutter documentation: Install Flutter.
Flutter Web: Ensure that you've enabled Flutter web by running the following command in your terminal:
This code creates a simple Flutter web app with a button and a text widget.
Step 2: Add Web-Specific Dependencies
In your 'pubspec.yaml' file, make sure to add the necessary dependencies for web development under 'dependencies':
dependencies:
flutter:
sdk: flutter
flutter_web: any # Add this line for web support
flutter_web_ui: any # Add this line for web support
Save the file, and then run the following command to get the dependencies:
flutter pub get
Step 3: Run the Web App
To run your Flutter web app, use the following command:
flutter run -d web
This command will start a development server and open your web app in a web browser. You can access it at 'http://localhost:5000' by default.
Step 4: Test the Web App
You can interact with your web app in the browser just like you would with a regular web application. Click the "Click me!" button to test your app.
Part 3: Build and Deploy the Flutter Web App
Step 1: Build the Web App
To build your Flutter web app for production, use the following command:
flutter build web
This command generates optimized files in the 'build/web' directory.
Step 2: Deploy to Hosting Service
You can deploy your Flutter web app to various hosting services, such as Firebase Hosting, GitHub Pages, Netlify, or any web hosting provider of your choice. Here's a basic example of deploying to Firebase Hosting:
Install the Firebase CLI by running 'npm install -g firebase-tools'.
Initialize Firebase in your project directory:
firebase init
Follow the prompts to set up Firebase Hosting.
Deploy your app to Firebase Hosting:
firebase deploy
Firebase will provide you with a hosting URL where your Flutter web app is now live.
Conclusion:
You've successfully created a Flutter web app, tested it locally, and deployed it to a hosting service. Flutter for web development opens up exciting possibilities for building cross-platform applications that work seamlessly on both web and mobile. You can now explore more advanced features and build full-fledged web applications with Flutter.
