What is Flutter web ?

Flutter Web :- Although Flutter was primarily focused on developing cross-platform Android and iOS apps, it is no longer limited to developing mobile apps solely. Desktop and online apps are now possible to create using Flutter in web.

If you want to experiment with Flutter for Web, here is the guide for you. Let us now read without further .

Initially We’re concentrating on three app scenarios in this first version of web support:

PWAs (progressive web applications) combine the reach of the web with the functionality of a desktop app.
Single-page applications (SPAs) load only once and send data to and from the internet.
Flutter mobile apps are being ported to the web, allowing for common code between the two experiences.

What’s the difference between Flutter and Flutter Web?

To grasp flutter website development, you must first grasp how Flutter works with mobile apps and how it differs from other frameworks. Flutter for Web and Flutter Desktop are programmes that connect with a backend via APIs (thus server-side rendering with Flutter isn’t viable). Mobile apps are visual interfaces that interact with a backend via APIs.

Flutter (Mobile) makes use of its own rendering engine, Skia, which allows the Software Development Kit (SDK) total control over every pixel of the screen and does it with precision and speed.

Flutter also has its own widgets (which you can get on pub.dev) that are developed entirely in Dart, allowing it to offer high-performing native apps.

Developers can select between two rendering engines in Web Flutter, namely:

  • DomCanvas
  • CanvasKit

DomCavas is an HTML DOM-based methodology for building, laying up, and painting Flutter widgets on the web using HTML/CSS/JS and the Canvas API. Flutter for Web, which pioneered this method, now defaults to DomCanvas.

CanvasKit, on the other hand, by Skia, makes use of WebAssembly and WebGL, allowing the browser to take advantage of hardware acceleration. This increases the efficiency with which complex and intensive graphics can be rendered. CanvasKit is currently in beta, so use caution while utilising it in production.

Flutter Web’s Advantages Here are a few advantages of adopting Flutter for Web in your business:

  • Animations, transitions, and graphical effects may all be rendered using Flutter web.
  • It has the ability to handle large volumes of data.
  • Both Cupertino and Material design UI components benefit greatly from Flutter.
  • It can run a game engine with improved physics and animations for specialised products.
  • PWA support is available in Flutter.
  • It can produce animations at speeds of up to 60 frames per second.
  • flutter website allows you to run JavaScript code. It’s a terrific alternative if you need to investigate an SDK or JS library.
  • As an embedded element, Flutter Web can work with existing web apps.
  • Pub.dev offers a large number of commercial and open-source libraries.

Flutter Web’s Drawbacks

  • flutter website isn’t optimised for search engines. As a result, different web frameworks may produce superior outcomes in terms of product promotion on search engines.
  • Flutter Web’s plugin support isn’t as good as it might be.
  • Because Flutter is currently in beta, app performance will be slower.
  • Flutter Web’s Hot Reloading functionality is challenging. You may either use the command line to run webdev serve –auto-restart or manually reload the website.
  • Flutter web developers are unable to alter the JavaScript, CSS, or HTML code that is generated.
  • It has limitations when it comes to Flutter API support.
  • The load size of Flutter web may appear to be inadequate when compared to traditional web development. The minimal payload size in HTML is 1.8 MB, however CanvasKit adds an extra 2 MB to the payload to improve speed.

How Do You Create Your First Flutter Web App?

You don’t need any prior knowledge of Dart or other internet programming languages to create a Flutter app. The official Flutter Web documentation will walk you through the fundamentals. Here’s a step-by-step guide to help you develop your first Flutter Web app project:

Make sure you have Flutter version 1.5.4 or above before starting your first Flutter Web app project. Install Dart 2.3 as well for app development. You can use the following commands:

$ flutter channel stable
$ flutter upgrade
$ flutter config --enable-web

Type the following in your command line to make sure you’re updating the correct version:

$ flutter doctor

It will show the current state of the installation. Run the following command to get the Flutter Web development tools:

$ flutter packages pub global activate webdev

Make sure the $HOME/.pub-cache/bin directory is included in the path now. It makes it easier to utilise the webdev command directly from the terminal. For macOS, type the following commands:


Restart your computer after that.

Select an IDE for creating a Flutter web app now. Here are the alternatives for you to choose from:

  • IntelliJ
  • Android Studio is a programme that allows you to create
  • Visual Studio Code is a graphical programming environment.

Different approaches are taken by these IDEs. You can choose your chosen one based on your suitability. VS Code is a web development tool that developers can utilise. To access the command palette, open VS Code and press ctrl + shift + p. Type: after you’ve opened the command palette:

Flutter: New Web Project

Visual Studio Code will ask for your permission to install Stagehand. Type the following to manually install Stagehand, a Dart Project creator:

pub global activate stagehand

By giving your project a name and a location, you may create a basic project demo.
The pubget command will run through your project automatically, loading all of the necessary packages.

Visual Studio Code will now ask for permission to install webdev automatically. You can still manually install it by executing the following command:

pub global activate webdev

To run your project, type webdev serve in the command line. Then, in the supported Chrome window, you’ll be able to access your first example project.
