Flutter is one of the most demanded technologies that allows developers to create interactive web apps. Flutter web development opens up possibilities for building cross-platform apps with a unified codebase.

This guide will explore all aspects of Flutter for web development, from installation to creating layouts and animations. So let’s get started!

What Is Flutter?

Flutter is an open-source mobile app SDK developed by Google that helps Flutter app developers write apps in Dart and then compile them into native code. In other words, it allows developers to create apps on Android and iOS without having to learn Swift or Java programming languages.

Moreover, Flutter for the web is a new project which will allow you to develop web applications using Flutter. It means you can use your existing knowledge of how Flutter works and can build desktop applications as well as mobile apps. You will be able to share most of your code between both platforms.

It opens up many possibilities, such as sharing assets and logic between both platforms Android and iOS while still being able to control platform-specific features such as animations and UI components!

How Flutter for the web is different?

Flutter for the web is different from other cross-platform frameworks like React Native and Cordova. While React Native and Cordova are essentially mobile apps that run inside a browser, Flutter for web builds real native applications on a device’s operating system.

You can use any of your existing skills with JavaScript, CSS, and HTML to build a web app. You don’t need to learn an entirely new language or framework. Instead, you can leverage your existing knowledge of these languages to create high-quality apps quickly and easily.

Additionally, because Flutter for web uses standard technologies like JavaScript and HTML, it’s easy to integrate with existing codebases.

For example, if you have an existing website that already uses Angular or Vue.js, it will be easy to incorporate Flutter without rewriting large portions of your codebase.

Additionally, suppose you hire Flutter app developers who already know how to write android or iOS apps using Java or Swift but not JavaScript/HTML/CSS. In that case, they can still contribute by writing frontend code using their preferred language while using their Android/iOS development skillset on the backend.

Flutter web app development utilizes two additional rendering engines that are –

  • CanvasKit –This model allows the browser to take benefit of hardware acceleration
  • DomCanvas –This is an HTML DOM-based model employed to create and design Flutter widgets on the web.

Step-By-Step Process to Flutter Web Development

The steps stated below will help you in Flutter web development:

Step 1: Start Project

Before starting Flutter web app development, you first need to install the Flutter SDK and set up your development environment.

Once you have installed the Flutter SDK, you can create a new project.

Step 2: Create A Project

Step one is to create a new Flutter project and then add the flutter_web dependency to your pubspec.yaml file. This dependency will allow you to access all the tools and packages required to develop a web application using Flutter.

Next, you need to update your web entry point in the pubspec.yaml file. It will tell the Flutter tooling where to find your web application’s main Dart file.

Lastly, you need to update your project’s build settings so that it knows how to compile your Dart code for the web. You can do this by adding a new flutter_web target to your project’s pubspec.yaml file.

Step 3: Understand The Project Structure

Now that you have created a new Flutter project, it’s time to understand the project structure. The two most important directories in any Flutter project are the lib and test directories.

The lib directory contains all of your Dart code. This is where you will write the majority of your code when developing a web application using Flutter.

The test directory contains your unit and widget tests. These tests are run automatically when you run the flutter test command.

In addition to these two directories, there are a few other important files and directories that you should be aware of:

- The pubspec.yaml file is where you configure your project’s dependencies and other settings.

- The .metadata folder contains files that are used by the Flutter tooling.

- The .dart_tool folder is where the Dart SDK stores temporary files.

Step 4 — Design The Web Page

After understanding the project structure, the next step is to design your web page. You can add HTML and CSS code to the lib/main.dart file.

You can also use the built-in Flutter widgets to design your web page. These widgets are located in the flutter:ui library.

To add a widget to your page, you first need to import the library that contains the widget. Once the widget has been imported, you can add it to your page using the Widget class. For example, to add a text widget to your page, you would use the following code:

Widget text = new Text(‘Hello World’);

After adding the widget to your page, you can then customize it by setting the widget’s properties.

Moreover, you can also add event handlers to your widgets. Event handlers are functions that are called when an event occurs. For example, you can add an onClick() event handler to a button widget so that a process is called when the button is clicked.

Step 5 — Create A Home Page

Now that you have designed your web page, it’s time to create a home page. The home page is the first page — your users will see when they visit your web application.

To create a home page, you need to create a new file in the lib directory and name it main.dart. This file will contain the code for your home page.

Once you have created the main.dart file, you need to add the following code to it:

This code will create a home page that contains a title and a text body. You can customize this page by adding your widgets and event handlers.

Step 6 — Navigating One Page to Other

After creating the home page, you need to add code so that users can navigate from one page to another. To do this, you need to use the Navigator class.

The Navigator class is used to manage a stack of pages. The navigator can push and pop pages from the pile and provide information about the current page.

To navigate from one page to another, you must create a new page. Once the new page has been completed, you can push it onto the navigator’s stack using the push() method. For example, to navigate from the home page to a new page named MyPage, you would use the following code:

This code will push a new page onto the navigator’s stack. The new page will be displayed when the user navigates to it.

You can also pop pages off the navigator’s stack using the pop() method. This method will remove the current page from the stack and display the previous page.

You can also use the navigator’s stack to get information about the current page. For example, you can use the following code to get the name of the current page:

This code will return the name of the current page. You can use this information to perform different actions depending on the current page.

Step 7 — Create The About Page

Now that you know how to navigate from one page to another, it’s time to create the about page. The about page will contain information about your web application.

To create the about page, you need to create a new file in the lib directory and name it mypage.dart. This file will contain the code for your about page.

Once you have created the mypage.dart file, you need to add the following code to it:

This code will create an about page that contains a title and a text body. You can customize this page by adding your widgets and event handlers.

Step 8– Run and Test The Application

Now that you have created the home page and the about page, it’s time to run the application. To do this, you need to use the flutter_web tool.

The flutter_web tool compiles and runs Flutter applications for the web. To use the flutter_web tool, you need to install it on your machine. You can do this by running the following command:

$ pub global activate flutter_web

Once the flutter_web tool has been installed, you can use it to compile and run your application. To compile your application, you need to run the following command:

$ flutter_web build

This command will compile your Flutter code into JavaScript. Once the code has been compiled, you can run your application using a web server.

You can also use the flutter_web tool to hotreload your application. Hot reload allows you to change your code and see the results immediately in the browser. To use hot reload, you need to run the following command:

$ flutter_web serve — hotreload

This command will start a web server and hot reload your application whenever you change your code.

You can also use the flutter_web tool to deploy your application to a web server. To do this, you need to run the following command:

$ flutter_web deploy

This command will compile your code and deploy it to a web server. You can then access your application at the URL provided by the flutter_web tool.

Now that you know how to use the flutter_web tool, it’s time to test your application. For this, you can do manual testing, or you can use a tool like Selenium.
