Flutter

Flutter is well documented and powered by Google. Flutter's user interface and user experience is slightly better than React Native.

I have experience with react and React Native. I would say that the idea behind all those frameworks are quite similar.
However, I found the javascript-based frameworks a bit more accessible as you could utilise your javascript knowledge. Here, Flutter works with its own language. This has advantages and disadvantages sometimes. I found the community around javascript frameworks bigger and therefore sometimes more helpful. However, Flutter does a good job here as well.

I think the main argument for Flutter is its usability for less experienced developers. If you do not have knowledge in javascript or other programming languages then I think it is much easier to start with Flutter than with another framework like react. I think the package that you get form scratch is better than in the other frameworks were you have to set up and learn a lot more before you can start.

I have used Flutter for cross-platform applications which are unique in the tech industry, I like the user interface created with Flutter.

We initially developed the application only on Android Studio (It was the best and easiest alternative to build with libraries available on Github). But when needed to scale the operations to iOS, Flutter comes in handy, and we had to dump all the development we did on Android Studio. It was a drawback back then, as we had many sleepless nights while updating Android code, but it is all worth it today.

- Like it better than other solutions, or building native on both platforms.
- React Native has a good advantage with language and amazing web support.
- React Native is easier to jump in for web engineers.
- For basic use cases, and simple apps, flutter is fantastic. Easy to build and more importantly fun!

I have not used Dev Express Universal and Selenium Web Driver much besides in the demos that were provided to our company. We compared the demos and went with Google Flutter because it worked well and looked noticeably better than the other products. While I am unsure of the pricing differences, the functionalities were comparable.

Flutter is a bit different from Android Studio, the latter one being an Integrated Development Environment (IDE) while Flutter itself is a Cross-Platform Mobile Development SDK (Software Development Kit). Flutter provides the access to the native features and built-in plugins and other SDKs as it allows you to use and reuse previously developed codebase on JavaScript, Swift, and Kotlin.

I selected Flutter because of Flutter's awesome, pre-build UI components. It makes my life as an indie dev easy and fun. At the time, I had never built an application with React Native, so this was a fantastic introduction to cross-platform development. That said, as someone who typically builds his web apps using Next.js (a cousin of React), I'd probably go back to React Native before Flutter.

I think that Flutter is now much better than Microsoft's Xamarin and the old Apache Cordova. I was able to go from a concept design to a working application in almost no time and with almost no experience with Dart at all. It helps (but it is not a requirement) to have some background in developing mobile applications, so if you have already some experience, it will be good for you.

Way less tweaking to have a cross-platform experience, better performance, and feels more like a native app.
But the community, while growing, is still smaller than React Native. This can cause issues with specific use cases as it's harder to find help online.

React Native seemed like a comparable and equally valid choice to Flutter. Performance, ease of development, and support are roughly equal between the two products. Dart, to me, felt easier to work with than Javascript or Typescript. Flutter SDK tools and VSCode extensions made Flutter feel easier to work with and develop. Additionally, Flutter felt like a new, up-and-coming cross-platform solution that would be around for quite some time, considering that it's used by a number of large companies, including Google itself in apps like Google Pay. For this reason, we decided to go with Flutter, but I also wouldn't say that React Native is a worse choice, I think it more so comes down to personal preference.

The app generated by Flutter doesn't change upon OS versions as in native apps or other cross-platform apps. The running speed of apps is much faster than its competitors like react-native and Cordova. It's lightweight and faster to compare to other cross-platform. The hot reload is super easy to use and tweak your UI. Lots of widgets available, the promise of unified development environment that will cover many platforms.

The main alternative to Flutter I have experience with, is Qt framework. For a long time, Qt was the go-to if you wanted a cross platform desktop application, probably written in C++ or Python, that could take on the 'look and feel' of the target platform. However, Qt is somewhat hampered by its licensing, in my opinion, and its relevance has diminished with the dominance of mobile platforms, and newer design philosophies. Qt is also a pain to maintain. In comparison, Flutter and Dart are totally free and open, make use of more modern approaches to app development, and let you achieve results VERY quickly. They are also a pleasure to use.
