How Does Flutter Web Work?

Flutter code, which is basically written in the Dart programming language, needs to be converted into web-compatible code by Flutter Web. This way, it will be visible in the web browser. Check out how Flutter Web functions:

Framework Dart

Browser Language

 1) Writing Code in Flutter: Flutter is a framework created by Google for building user interfaces. Developers use the Dart programming language to write their app's logic and UI. Flutter widgets and components are used to define how the app looks and functions.

 2) Compilation to JavaScript: Web browsers understand JavaScript, HTML, and CSS, so Flutter code needs to be converted into these languages to work on the Internet. This conversion process is called transpiration. The Dart code is transformed into efficient JavaScript code. Your Flutter app's logic and rendering instructions are written in JavaScript.

3) Generation of HTML and CSS: This JavaScript code generates HTML and CSS files for your web app. These files define the structure and styling of your web application. When a user opens your web app in a browser, the HTML file loads the JavaScript code.

4) Canvas and DOM Manipulation: Flutter Web uses both the HTML Document Object Model (DOM) and an HTML5 canvas to create the user interface. Unlike traditional web programming, Flutter does not directly modify DOM elements. Instead, it draws on an HTML5 canvas, which allows for fast updates and rendering. Flutter also creates a virtual DOM-like structure to efficiently manage UI updates.

5) Web Rendering Engine: The Skia graphics engine is used in Flutter Web to render web content. Skia ensures smooth and efficient rendering, providing a responsive user experience.

6) Development Server: A development server is launched when you run your Flutter Web application in development mode using the Flutter Run -d web command. This server serves the compiled HTML, CSS, and JavaScript files. It allows you to access and use your web app on a web browser during development.

7) Hot Reload: Flutter Web development has a hot reload feature. This lets you see the effects of code changes immediately without restarting the application. Hot reload speeds up the development and debugging processes.

8) Testing on Different Browsers: To make sure your Flutter Web application works well on different web browsers, you should test it on Google Chrome, Mozilla Firefox, and Microsoft Edge. Even though Flutter Web is designed to work well on these browsers, there may still be differences in behavior that require testing and adjustments.

9) Production Build: Use the Flutter build web command to create a production build for your Flutter Web app. This command generates optimized static files that can be deployed on web hosting services or stored on a web server.

How Can I Shift My Current Project to Flutter Web?

I will guide you through a step-by-step process of shifting your existing project to Flutter Web.

Step 1. Check Flutter Version

It is pivotal to use the current Flutter version. The latest version will ensure that the support for the Web will be stable and feature-rich. If you are unaware of your Flutter version, check by running the code below:

Bash Flutter Version

If you are not using the latest version, it is advisable to go for the update.

Bash Flutter Upgrade

Step 2. Enable Web Support

Have you enabled web support for your Flutter project? If not, you can run the command below in your project directory. This will create and configure all the necessary files related to your web projects in Flutter.

Bash Flutter Create

Step 3. Select Your Preferred Browser

A browser will be mandatory to run your Flutter project. Google Chrome and Firefox are popular ones. You can make your choice and install it on your system.

Step 4: Run Your Project

Run your project on the web with the following code. It will build and launch your web app in the development server. This will open a new tab in your chosen browser and the running application.

Bash Flutter Run

Step: 5 Debugging and Hot Reload 

The tools available for mobile development are also available for Flutter web development. Press R in the terminal to conduct a hot reload when you change your code. You can also use the Flutter debugging tools at this time.

Step 6: Testing Different Browsers

Testing your application on many web browsers is a good idea when creating for the web to verify compatibility. To check how your app renders and operates, manually open it in various browsers.

Step 7: Building for Production

Once you are ready to launch your Flutter web app to production, create a production build with this code. This code will help you generate optimized static files that can be hosted on a web server.

Flattering Points of Flutter for Web

  1. Code Reusability

This feature can be considered as one of the highlighting ones in Flutter for web apps. Save time and effort by utilizing the existing code of your mobile app for building a web app.

  1. Hot Reload

This functionality facilitates developers to check changes in real time. Both the Web development and debugging speed up by this quick development cycle.

  1. Consistent UI

Flutter for web apps provides a uniform and visually appealing user interface (UI) across several platforms. This keeps the brand's identity and user experience consistent.

  1. Performance

Flutter renders user interfaces using the Skia graphics engine. This allows mobile apps as well as web apps to deliver effective performance.

  1. Large Developer Community

The developer community for Flutter is large and vibrant. There are multiple tools, libraries, and software programs available to support developers in their web development journey.

  1. Single Codebase

With Flutter, managing multiple codebases is simplified because you can manage a single codebase for both web and mobile applications.

Flutter's Drawbacks for the Web

  1. Limited Web Support

Although the latest news on Flutter supporting the Web is true, it has limitations. Flutter framework still lacks some of the web-specific features and functionalities which is available with React or Angular, two popular web-focused frameworks.

  1. Web Application Size

Flutter web applications may be larger in size as compared to other web development frameworks. This affects page load speed and creates an issue for users with slow internet.

  1. SEO Problems

When compared to conventional web applications, Flutter web apps could experience SEO problems. In Flutter, proper SEO optimization may be more difficult. You need to hire a reliable Flutter development company to make sure your project doesn’t experience any SEO setbacks.

  1. Browser Compatibility

Flutter web apps might not be as interoperable with all browsers as conventional web apps are. Your app may need to be tested and modified for different browsers. There are also certain restrictions on the support of Flutter APIs.

  1. Learning Curve

If you have prior expertise with web development using other frameworks, switching to Flutter for the web may include a learning curve.

  1. Limited Third-Party Integrations

Despite having a developing ecosystem, Flutter may not have as many plugins and third-party integrations for web development as other, more well-known web frameworks.
