We all know Flutter, an open-source mobile and web development technology created by Google. Flutter was originally designed to create mobile applications, but today it also supports web development, making it very attractive to businesses. 

I would like to illustrate here the pros and cons of this solution, and if possible help entrepreneurs understand if this technology is suitable for their next project.

What is Flutter?

Technically speaking, Flutter is a UI framework that allows you to create Native and hybrid applications for mobile, web and desktop from a single source code. 

Its programming language is Dart, but it also offers various customizable widgets. 

Benefits of Flutter 

1. Single code for multiple platforms

Code proliferation is one of the biggest problems for the developer. Flutter solves this problem: one of its main advantages is the possibility of using a single source code for develop hybrid applications for mobile, web and desktop. This inevitably reduces time and resources.

2. Performance 

In terms of performance, Flutter does a very good job. Web applications that require complex interactivity and animations run very well in Flutter, they run smoothly and are generally very responsive.

3. Hot reload

Flutter's Hot Reload feature allows developers to immediately see the results of code changes without having to recompile the entire application. 

4. Customizable widgets

As mentioned, Flutter widgets are a real strength and offer great flexibility compared to other development environments.

5. Many packages and rich community

Sometimes the community makes all the difference, and that is the case with Flutter. The available packages continue to expand, to allow libraries and tools to developers without too much effort. 

disadvantages by Flutter

1. Upload size

One of the main disadvantages of Flutter for web development is the size of the generated bundle. Flutter applications tend to have a larger initial bundle than other traditional web technologies, which can impact loading times, especially on slow connections.

2. SEO and accessibility

Currently, Flutter doesn't offer much support for SEO and web accessibility. Flutter applications are essentially canvas HTML, which can limit their indexing by search engines.

3. News

It may seem trivial, but Flutter is relatively new. Sure, it is gaining popularity, but its “youth” implies inexperience, and there remains the possibility that it contains bugs and limitations compared to more consolidated web solutions such as React or Angular.

4. Integration with existing technologies

Using some JavaScript libraries may not be straightforward and may require workarounds or alternatives, increasing the complexity of your project.

Flutter vs React Native and Kotlin Multiplatform Mobile (KMM)

When it comes to choosing a framework for cross-platform development, Flutter goes head to head with Kotlin Multiplatform Mobile (KMM) and React Native. In my opinion, there are several reasons why Flutter could win in this even-keeled competition.

…Compared to Kotlin Multiplatform Mobile (KMM)

KMM, ideal for having applications that run on iOS and Android, focuses primarily on business logic and not on creating shared UIs. Bottom line: developers still have to write separate native code for UIs on each platform. In contrast, Flutter offers a true cross-platform solution, allowing developers to create fully shared and customizable UIs from a single source code. This not only reduces development time, but also ensures visual consistency across platforms.

…Compared to React Native

React Native, developed by Facebook, is another popular cross-platform development technology. It uses JavaScript and allows you to write shared code for Android and iOS. 

One small disadvantage, compared to Flutter, is that React Native relies on bridges to communicate with native components.

This can unfortunately cause performance issues in complex or animation-heavy applications. 

Flutter, on the other hand, compiles Dart code directly to native code, eliminating the need for bridges and providing superior performance. Flutter also offers a richer range of native widgets that can be easily customized, while React Native often requires the use of third-party libraries to achieve the same functionality.

Flutter for Web Development: When to Use It

In summary, using Flutter for web development can be a good choice for web projects that require a rich and interactive user interface, and for development teams that are already using Flutter for mobile applications. 

It is great for startups and small businesses that want to reduce development time and costs while maintaining a consistent user experience across different platforms.

On the other hand, if your project requires advanced SEO optimization, high accessibility, or needs to integrate well with an existing web ecosystem, it might be more appropriate to consider other technologies, such as React, Angular, or Vue.js.
