Ever since Google released its first stable version in December 2018, Flutter has been the talk of the town. Since then, it is used to build amazing functional applications that ensure seamless performance. The intriguing characteristics and features of Flutter have helped developers to experiment with building complex applications using Flutter. During its initial days, Flutter app developers just concentrated to build cross-platform mobile apps for Android and iOS. However, web and desktop applications are on the plate to be announced later.
Before flutter website development was implemented, the project is recognized as HummingBird. And since the release of the Flutter Web preview on 7th May 2019, the flutter app development company has been using it to build highly interactive, graphic-rich, and engaging applications.
Being Google’s brainchild, this open-source toolkit leverages immense support in building a highly intuitive, responsive yet incredible experience. Big-labeled brands like Alibaba, eBay, and The New York Times have already started reaping the benefits of this impactful framework.
With such an immense response, this article will help you to understand Flutter architecture. It will also guide you with the prerequisites needed to build an app and how you can build your first flutter app. So, let’s start with your first flutter app development.
Flutter App Development Architecture
Flutter architecture for web applications is quite different as compared to mobile. It makes use of a variety of tools and libraries to render browser support. The first layer of flutter web app architecture consists of built-in tools, widgets, and themes.
A few Key Takeaways of Flutter for Web apps are:
- The API for web and mobile apps is the same, and only a few features won’t be implemented in the web version.
- The flutter for the web is slowly growing and the default interactions are evolving. Hence, flutter for web app applications provides a feel like a mobile app rather than a web application.
- Though Chrome is the only supported browser as of now, other browsers like Safari, Edge, and Firefox are under a plan to be implemented for use.
Now that you’ve got an idea about how flutter for web apps works, let’s start with how to build a basic flutter app in the web version.
Pre-Requisites To Build Flutter App:
To create a Flutter app with web support, you need the following software:
- Flutter open-source Software development kit. If you want to see the installation instructions, you can see them here.
- Chrome browser to debug a web app.
- An IDE that supports the flutter web app. There are multiple options available. You can install Visual Studio Code, Android Studio, IntelliJ, IDEA, and install flutter and dart plugins to enable language support and tools to run, debug, reload and refactor the web app with an editor.
If you’re still confused and want to build your flutter app, you can hire a flutter app developer from Concetto Labs. The company holds 10+ years of experience in serving the industry with award-winning complex yet interactive mobile and web experiences to 100+ clients across the globe.

How to Build and Run the First Web App Using Flutter?
Let’s create a new project with web support.
To setup flutter webview, run the below commands to use the latest Flutter SDK from the beta channel along with enabling web support:
The flutter channel beta
flutter config –enable-web
Once the web enables, the flutter device will command outputs a chrome device that opens the chrome browser with your app running and a web server will provide the URL that serves your app.
2 connected devices:
After enabling the web support, you can restart your IDE. Now you can see the chrome and web server in the device pulldown.
Create and run
Creating a new flutter project with web support is nothing different than creating a new flutter project for other platforms.
Once you’ve configured your development environment for web support, you can create and run a web app either in IDE or from the command-line interface.
Once you’ve configured your environment to support web apps, make sure to restart the IDE if it’s already in running mode.
All you need to do is just create a new app in your IDE and it will automatically create an Android, iOS, and Web version of your application. From the device pulldown, you need to select chrome web and run your app to see if it’s launched in chrome or not.
To create a new app that also includes web support along with mobile support. You need to run the below commands eliminating “myapp” from your project name.
flutter create my-app
To serve your app from the localhost in Chrome, enter the following command from the top of your package:
flutter run -d chrome
This command will launch the app using a development compiler in the chrome browser.
Now use the below command to generate a release build
flutter build web

Adding Web Support to an Existing Application
If you’ve already created a project and want to extend it by adding web support, you can run the following command from the terminal from the root project directory.
