Everything You Need to Know About Flutter for Web Applications

The craze of “web apps” is waving high and every business wants to surf higher on these waves than their counterparts. 

Why Web Apps?

Well, in a study conducted by the top 30 PWAs report, web applications boast over 35% higher conversion rate compared to native applications. 

Despite the extensive time spent on mobile devices, desktops remain favoured for their perceived security and superior user experience.

But not every organisation is fortunate enough! Developing a web app requires extensive research, especially the right framework!

In the year 2022, Flutter, Google’s software development kit, emerged as the dominant force in cross-platform technology, surpassing its main rival, React Native, and officially claiming the leadership position.

Planning to use Flutter for web apps? Let’s dive in!

Overview of Flutter

Flutter, Google’s versatile UI library, allows developers to craft native, high-performance applications across various platforms including desktop, web, and mobile, all from a single codebase. Utilizing the Dart programming language, Flutter seamlessly blends Cupertino and Material Design to deliver visually appealing user interfaces that feel native and adapt effortlessly to any device.

One of Flutter’s key advantages lies in its code reuse capabilities. If you’ve already developed a mobile app using Flutter, you can leverage the same codebase to build your web application without the need for extensive rework. This means you can maintain consistency in logic, UI elements, and layouts across platforms, enhancing developer productivity significantly. Additionally, due to the inherently simpler nature of web applications compared to mobile apps, leveraging Flutter for web development can streamline the process and expedite time-to-market.

Speaking of popularity, Flutter has over 159K stars on GitHub (January 2024), and it’s one of the most popular mobile frameworks available.

Sounds interesting, doesn’t it?

Well, now that you have understood Flutter’s ins and outs, let’s understand its benefits for “Web App” development and then Flutter web tips. 

Benefits of Flutter for Web App Development

Here is the list of the key reasons to consider Flutter for web app development. 

1. Reduces Development Costs

Flutter for Web offers significant cost-saving benefits by enabling the creation of three distinct applications – for desktop, web, and mobile – using a single codebase. This streamlined approach allows development teams to work cohesively, maintaining a consistent pace and reducing the need for separate vendors specializing in different technologies.

While it’s true that Flutter eliminates the need to duplicate certain functionalities like payment processing or social media authorization across multiple platforms, the cost savings may not directly translate to a tripled amount. Other factors such as project complexity, maintenance requirements, and specific client needs must also be considered.

2. Enhanced User-Centric Experiences

According to the founders of Flutter’s Web platform, Flutter currently excels as a tool for integrating interactive experiences into websites. As a robust UI framework, Flutter offers app-centric services that make it an ideal solution for Progressive Web Apps (PWAs), Single Page Apps (SPAs), and enhancing existing Flutter mobile apps.

3. Easy scaling Verification of Idea 

Flutter’s cost and time efficiency make it an exceptional choice for Proof of Concept (PoC) projects and verifying product ideas. Within just a few weeks, developers can create a fully operational application that can be readily released to app stores and distributed via the web. 

In the event of success, scaling both mobile and web applications is a viable option. For instance, extending cross-platform mobile apps to native solutions can offer even greater flexibility in tailoring the product to specific target audiences.

Many corporate giants including Airbnb, have followed this trajectory. After achieving success with their cross-platform mobile applications, Airbnb opted to transition to native solutions. This transition provided them with increased freedom to customize their product to better meet the needs of their target demographic.

4. Get Access to Native Features

Another prominent advantage of Flutter for web apps is its seamless access to native features. Essential functionalities such as geolocation and camera usage traditionally require implementation using native languages. However, with Flutter, developers can harness the power of Objective-C, Swift, or Java to integrate these native features seamlessly into their applications.

Furthermore, Flutter boasts performance that rivals native applications. Unlike many other cross-platform frameworks, Flutter does not rely on intermediate code representations. Instead, Flutter apps are compiled directly into machine code, ensuring optimal performance and indistinguishable user experience from native applications.

5. Robust Flutter Community

Flutter benefits from a robust and dynamic community of developers, fostering a thriving ecosystem. This community actively engages in knowledge-sharing, offers support, and collaborates on open-source projects, facilitating easier access to solutions and resources for developers. 

The community-driven ecosystem ensures that developers have access to an extensive array of libraries, packages, and plugins. These resources can be leveraged to augment app functionality, expedite development, and streamline the overall development process, contributing to Flutter’s continued growth and popularity.
