In this article, you’ll learn about all the benefits and drawbacks of launching a progressive web app with Flutter. Here, we’ll share our experience with Flutter Web, demonstrating how we avoided all potential pitfalls to be convinced that a Flutter-powered PWA is a viable and practical solution.
What are progressive web apps?
A PWA is a technology that visually and functionally transforms a website into an app. Then, this can be viewed in a browser or installed on a smartphone like a regular mobile app would. Such apps can be built using a variety of technology stacks, but we will focus on Flutter as one of our primary areas.
Progressive web apps are gaining popularity in the global market, and for a good reason: they save business owners millions of dollars on mobile development. A web version can help you introduce your audience to your digital product.
Progressive web applications are browser-based applications that are supported by
Android, iOS, macOS, Linux, Windows, and Chrome OS are supported.
Browsers include Chrome, Safari, Firefox, and Edge.
PWAs can
Work without the Internet,
Work in the background,
Obtain access to the OS capabilities of a smartphone,
Send push notifications,
Acquire updates,
Launched via a shortcut on the main screen of a smartphone.
The Advantages of Progressive Web Apps
Separate from the stores: PWAs do not need to be published in app stores; users can find them in their browsers and install a shortcut on their smartphones. You can save money by not posting and promoting the app in stores and avoiding moderation policies.
It saves space on your smartphone: One of the reasons users refuse to download an app is that it needs to be more significant. A typical app is 20 to 50MB in size, whereas a web app is less than 1 MB.
It reduces traffic: You don’t need to waste your traffic on it because you don’t need to install the entire web app. It works in a mobile browser, which consumes significantly less Internet traffic.
The page loads quickly: On average, such applications load in less than a second.
It works without an Internet connection: They are independent of the Internet due to caching.
Cross-Platform Compatibility: PWAs can run on various devices and platforms, making them accessible to a broad audience without the need to develop separate apps for each platform.
Engagement: Features like push notifications can help boost user engagement, like native mobile apps.
Flutter and PWAs
Flutter, a UI toolkit from Google, is renowned for its ability to create natively compiled applications for mobile, web, and desktop from a single codebase. While it is primarily known for building mobile apps, it also offers the capability to create web applications. Flutter for web, often referred to as Flutter Web, leverages the same codebase as Flutter for mobile, enabling developers to build web apps with the same speed and efficiency.
Why Flutter for PWA development?
80-95% of the code base can be reutilized across platforms. You only need to modify the platform’s features and the user interface. They will still use fewer resources than starting from scratch.
Such projects are more easily supported.
Because your progressive web app will require fewer developers, you can reduce your budget (by 40% on average).
It is simpler to test. The code is validated once for all platforms.
Support and communication become clearer.
A Flutter project can be quickly compiled into a PWA and back again.
Tech Under the Hood
Progressive web apps are made up of two parts:
The Service Worker layer sits between the app and the external servers. It specifies which strategies should be used for which resources.
App Manifest is a JSON file linked to an app’s HTML page. It specifies how the app will appear and behave once installed.
Benefits of Using Flutter for PWAs
Code Reusability: Leverage the power of Flutter’s single codebase for both mobile and web, reducing development time and effort.
Rich User Interface: Flutter’s rich set of widgets ensures your PWA looks and feels great, delivering a polished user experience.
Performance: Flutter Web is designed for high performance, ensuring your PWA loads quickly and runs smoothly.
Community and Support: Benefit from the growing Flutter community and extensive documentation for guidance and problem-solving.
Wrapping Up!
Flutter and Progressive Web Applications (PWAs) make a strong team, allowing developers to create high-quality web apps for different platforms effortlessly. With Flutter’s single codebase for mobile and web, you save time and resources while delivering engaging user experiences. Whether you’re a mobile app developer looking to expand to the web or a web developer exploring new technologies, Flutter for PWAs is a versatile and efficient solution. Embrace PWAs with Flutter and take your web apps to the next level.
