Despite the growing mobility and an extensive range of solutions offered by native apps, web apps are still popular and robust. Many people research their top brands on mobile, but when it comes to transactions, they prefer the web application.

The advent of progressive web apps saw more businesses creating web solutions and mobile apps. According to a study, PWAs have a 36% higher conversion rate than native applications. While people spend long hours on mobile, they trust desktops for security and experience.

Most mobile apps fail to convert owing to the poor user experience, apps not optimized for the different devices, and the inability to view the product specifications properly.

The ease of scaling, the holistic control, and the flexibility that a web app offers is the main reason why more businesses are opting for the platform-agnostic, browser-compatible solution.

The Growing Need for Web Apps

Flutter for Web: How it Works?

Is flutter ready for the web? The Flutter web framework works with two different rendering engines- HTML and CanvasKit. Developers can use either engine to render website apps the same way they would render mobile apps. For this purpose, the Flutter web framework first converts the project into a native app code before deploying it. At this point, you will see a single index.html file for the whole project.

The browser script that you use will be JavaScript or C++. You can also use WebAssembly and WebGL as part of this framework to build single or multi-page web apps.

Hire Flutter Developer to Check Web App Performance

It isn't enough to develop a web application; you need to create high-performing solutions actively. To measure the app's performance, you need to render massive data. Secondly, you need to check how the transitions, effects, and animations can impact your business app. for this, you can use DomCanvas or CanvasKit engines.

The rendering engine converts the code you have written in Dart to CSS or HTML

This will help execute the widgets and check for performance

Note: Owing to the limitations of each engine (DomCanvas comes with lesser payload and CanvasKit needs significant changes to calculate performance), it becomes difficult to measure the speed and performance. You might increase the wait time when improving performance.
