Businesses, along with programmers and developers from all across the globe, welcomed the technology with open arms, quickly adapting to flutter app development to deploy high-performance, engaging applications.

As a result, today, there are more than 1 million Flutter-based apps available in the market, up from 500,000 in mid-2022.

Flutter web app benefits

While initially used for crafting mobile applications, Flutter is now making waves on the web, demonstrating a seamless transition from mobile to desktop. With Flutter web app development, you can create impressive and complex UIs with ease without impacting the performance. Also, web apps built with Flutter are much faster and perform better.

If you want to try Flutter for your web application, this article is for you. Here, we will discuss the detailed step-by-step process of building Flutter web apps successfully for your business. We will also discuss the associated costs.

But before that, let’s begin by quickly understanding the underlying benefits of flutter web development for businesses of all sizes.

Develop a web app for your business

Why Should Businesses Choose Flutter Web App Development?

Flutter’s unique approach to using a single codebase for mobile and web platforms removes the need to invest in separate development. It not only saves time, money, and resources but also ensures consistency across various devices, providing a seamless user experience.

In addition, Flutter boasts a rich set of pre-designed widgets that help create visually stunning, highly functional, and complex UIs easily. It also features a hot reload functionality, which automatically updates UI content when the code changes, leading to smoother coding.

Furthermore, Flutter speeds up the web app development process, reduces development costs, and helps build an app with smooth animations and interactive designs.

On that note, let’s dive into the key benefits of Flutter and discover the reasons why you must use Flutter for web application development.

Why to Choose Flutter Web App Development

Enables Mobile and Web Development at the Same Time

Flutter is an ideal choice for businesses looking to develop an app for the web and mobile simultaneously. With Flutter, a single codebase can be used to develop apps for different platforms. This saves time and money as well as reduces stress related to developing two apps together. Also, needless to say, this significantly reduces the cost of development.

Offers Top-Notch User Experience

Flutter for web apps enables the creation of flexible and impressive UI. The availability of a wide range of widgets allows developers to create stunning user interfaces for users. Also, the native capabilities of this framework facilitate the high performance of web apps and a seamless user experience.

Ideal for MVP

Using Flutter for web application development can help showcase your MVP to investors. MVPs are the first versions of the app that have the most basic features. They are ideal for testing the concept and collecting the first feedback to make a better app in the next iteration.

Additionally, developers don’t require separate backends for building simple MVPs due to Flutter’s compatibility with Firebase. Hence, Flutter for MVP development is the perfect choice if you don’t want to spend a lot of money.

Google Guaranteed

Apps created using Flutter get years-long support from Google as they use the technology themselves. You can be guaranteed that Google will fix bugs, release new versions, and contribute to Flutter technology as much as they can.

Google is already utilizing Flutter in several new projects like Google Fuschia, proving that this framework will be around for a long time.

Now that we have looked into the key benefits of Flutter web development, it’s time to look into how to build a web application using the Flutter framework.

How to Build a Web Application for Your Business Using Flutter?

The Flutter framework is a perfect choice for projects impacted by time constraints and tight budgets. You can also use Flutter when your top priority is aesthetic design and seamless UX.

So, in case you are wondering how to develop a web app using Flutter, given below are a few steps you should consider before the development begins. These steps will help create your web app successfully – so don’t skip over them.

How to Build a Web Application Using Flutter

Conduct Market Research

The first and foremost step when using Flutter for web applications is to conduct in-depth market research to get valuable insights into the competitors and current market scenario. This helps you understand the important tactics used and mistakes committed by your competitors. You can learn from those mistakes and create a more innovative idea and a better strategy.

Know Your Target Audience

When opting for Flutter web development, knowing your target audience is critical. It will help you decide on the list of features for your minimum viable product (MVP). If you know what your audience wants, it will be easier to focus on what matters and put unnecessary features into the bin.

You can also take suggestions and opinions from users to know what they are looking for. Align your objectives with your user demands, and nothing can stop your web app from gaining ground. In this way, you can get more users for your application.

Choose Intuitive UI/UX Design

What is the first thing that attracts users to your web app? It’s the way your application looks and interacts with them. User-friendly and easy-to-use app features make it attractive to users. With Flutter, you can create an excellent UI/UX design as this framework offers color palette selection and eye-catching animations that provide its users with an impressive visual experience.

In short, your web app’s overall effectiveness can be measured by the optimal combination of its functionalities and attractiveness, which Flutter can offer.

Considering this, make sure your web app follows the below-mentioned basic rules:

  • It’s simple
  • It’s engaging
  • It’s intuitive

When integrating trendy app designs using Flutter, make sure that it not only looks appealing but interacts with the users while providing a faster and comfy experience.

Choose the Right Flutter App Development Company

The next step in Flutter web app development is to choose the right tech partner. The choice of app development company plays a significant role in making your web app user-friendly, intuitive, and aesthetically pleasing. The company you choose must have a sound knowledge of delivering excellent app designs to provide the best customer service. They should be able to create the Flutter app in a way that the user can perform its designated functions without any help.

Here are a few things you can consider before opting for Flutter web development services to make a web app:

  • Select an experienced Flutter web app development company.
  • Ask them about their app maintenance policy.
  • Look for the communication and collaboration approach of the company.
  • Pay attention to how well the company understands your project requirements.

Use your flutter web app idea

Build MVP

It is vital to test your Flutter application on target platforms before it is out in the market. MVP is that version of your app which only consists of the most crucial features. It will allow you to understand if your app will be successful or not. For a successful MVP development, hire a reputed Flutter app development agency that can guide you through the entire process.

Test Your App

When you use Flutter for web apps, it’s important to regularly test the app. For testing your web app usability and performance, you can follow the below-listed methods depending on your web app features and functionalities:

  • UI/UX testing – This kind of testing is done to assess many components of the software that users will interact with.
  • Regression testing – In this type of web app testing, each and every modification made to the website is reviewed to see if it breaks the website’s overall flow.
  • Functionality testing – It is a type of black-box testing that helps determine whether a web app meets the specified requirements.

Proper testing of your Flutter web app will help reduce app development costs and time, identify errors and bugs, and greatly improve your reputation as a service provider.

Host Your App

Once you have successfully tested the Flutter web application, you are required to select a server. You need to buy a domain name and mount an SSL certificate. Once done, pick a cloud provider, such as Google Cloud or Microsoft Azure. If you opt for one of these hosting choices, you’ll probably get everything you need.

Deploy Your Web App

Once you have the host and the code, you’re ready to go live. Upload your app to the hosting solution, and your customers can use it without any hassle. But this is not the end.

Once you have successfully launched your web app, make sure to track Flutter web performance using various in-app analytics tools, address users’ requests and concerns, and introduce updates to increase user engagement.

How Much Does It Cost to Build a Flutter Web App?

There is no one-size-fits-all approach when it comes to Flutter web app development cost. The app development cost using Flutter significantly varies depending on various factors such as the number of features, app complexity, software type, supported platforms, location of app development company, etc.

On average, flutter web app development costs can range from $25,000 to $200,000 or more based on your specific project requirements. Remember, it is only a rough estimate. For an exact cost estimation, you should contact a reputed Flutter app development company and discuss your project idea.
