Flutter Web and Desktop Limitations

Flutter has innovatively positioned itself as a solution to cross platform application development where app developers are able to build mobile, web and even desktop applications with one code base, yet have high performances and pleasing aesthetics. This being said, the web and the desktop versions of Flutter have some limitations inherent to the environments they are designed for that might turn into a problem for developers or users. This document addresses these issues and offers useful recommendations regarding the management of this type of risk.

The claims for web and desktop support appeared more recently while Flutter has a more developed mobile experience. The limitations arise due to:

• Lack of framework maturity seen in Web and Desktop scenarios.
• Limitations that are tied to the platform you work on such as issues related to rendering and performance.
• The conflict of interests between being more or less flexible across platforms while acting natively.
• This information becomes very important for developers to know how these can be avoided and whether to use flutter for their web and desktop applications.

1. Rendering Performance

• Limitation: Influtter Web apps, UI widgets and animations could be slower in regards to rendering especially in the complex widgets..

• Solution:

• Prefer the CanvasKit renderer if you’re running on web applications with high graphic needs..

• Improve widget trees by reducing hierarchy level and using RepaintBoundary..

1. Large Bundle Sizes

• Limitation: Flutter Web apps result in larger file sizes compared to native web apps, affecting load times.

• Solution:

• Enable tree shaking to remove unused code.

• Use deferred loading for features that are not needed at startup.

2. Limited Platform Features

• Limitation: Desktop apps lack deep integration with native OS features like system tray or global shortcuts.

• Solution:

• Use platform channels to implement native functionality.

• Explore community packages like bitsdojo_window for custom windowing solutions.

3. Browser Compatibility

• Limitation: Flutter Web apps may not behave consistently across different browsers.

• Solution:

• Test apps on multiple browsers, especially legacy ones.

• Use fallback solutions for features unsupported by some browsers.

4. Limited Ecosystem

• Limitation: Fewer plugins and third-party packages optimized for web and desktop compared to mobile.

• Solution:

• Develop custom plugins for specific needs.

• Contribute to open-source Flutter packages to improve ecosystem support.

5. Accessibility Challenges

• Limitation: Accessibility features are not fully supported across web and desktop platforms.

• Solution:

• Test and implement ARIA roles for better screen reader support.

• Use tools like Lighthouse to audit and improve accessibility.

• Continuously monitor updates to Flutter’s web and desktop support.
• Keep UI/UX simple for web and desktop to enhance performance.
• Leverage feedback from real users to prioritize optimizations.

 

Web and desktop applications could be successful in the Flutter ecosystem but it is accompanied by those problems. In my view, I have learnt that majority of these disadvantages can be solved through proper planning together with using advanced tools and methods. Which direction Flutter will go naturally, the support for web and for the desktop will only become stronger so that really the cross-platform solution Flutter is really worth it.
