The success of Flutter for web depends on the use case

Flutter for web can prove beneficial for your overall strategy, especially if your main cases are handled via mobile applications. Nevertheless, it's crucial to note that it doesn't serve as a substitute for established web technologies like React, Angular, Vue, or Svelte. As is common in the dynamic realm of technology, the suitability of Flutter depends on your specific needs and requirements.

What cases are suitable for Flutter web apps?

You already have a Flutter mobile app

It is a good choice if you already have a mobile app and want to build a web app quickly as an add-on. In such a situation, Flutter Web helps build a mobile app alternative way faster than if you start from scratch. As an example, it allows for reusing a mobile design and animations. Also, deploying such a web app is more straightforward - you only need to host it once, and it's available on all platforms.

You are digitalizing the B2B process

Let’s be honest. Flutter hugely shortens the time to market for shifting modern and beautiful interfaces. Still, some impediments like poor SEO support or time needed for the first load and rendering the website make it less optimal for regular B2C apps. However, those obstacles are totally irrelevant for most B2B applications, whose features still require a login page. In those cases, Flutter has close to no drawbacks and is perfectly suitable to digitalize existing products and build new B2B ventures. 

You need to handle some edge cases

It is a good choice if you already have an existing mobile app and the web app is helping you handle some edge cases. For example, we’ve worked with a Fintech client who had to upload certain financial information (i.e., P&L and Balance Sheet) to meet KYC requirements. It wasn’t convenient for users to do it on mobile. Therefore, we built the web version of an app in parallel to redirect users to it and make uploading their documents more accessible.

You want to build a Single Page App

A Single Page Application (SPA) is a web application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server. In SPAs, the content is loaded asynchronously, usually in the background, and the user experience is more seamless as it avoids the traditional approach of full-page reloads.

What is included in Flutter for web service?

Here, the range of additional services will depend on your specific case. We will have a different approach if you already have a mobile application and when you build a completely new app.
