Flutter is an open-source mobile application development framework created by Google. It is used to develop applications for Android and iOS, as well as being the primary method of creating applications for Google Fuchsia.
Flutter is well known for native app development, if you have android studio installed on your system, you can quickly start using it. This might not be the best choice for you if you do not wish to learn a new language, i.e. Dart and you do not know it already.
Xamarin is well suited for several reasons. The first, it allows companies to share code across platforms. If the app has a lot of business logic and a fairly simple UI, Xamarin is great for this use case. Xamarin also works well if the developers who will work on the app are already fluent in .NET. Xamarin is less appropriate if the company has a lot of developers. If there are plenty of resources to develop apps natively then the headache of dealing with Xamarin's issues are not worth the effort. If the UI is very complex and has difficult animations it's difficult to debug visual/performance issues in Xamarin.
Occasionally updates to the Flutter SDK result in wide-sweeping changes that seem to not be thoroughly tested and considered. Flutter sometimes evolves too fast for its own good.
While the 3rd-party Flutter package ecosystem is vast and rich, 1st-party support for basic things (audio/video playback, battery information, Bluetooth services, etc.) are lacking. You are occasionally forced to rely on an open-source package for use-cases that other platforms have native support for.
Documentation, particularly around testing, is lacking. While there are some great docs, like the Dart Style Guide, many Flutter-focused support documents are lacking in quality and real-world usability.
Flutter allows you to architect an app however you want. While this is a great feature, it also adds complexity and leads to the current state of Flutter's state management, where there are 50+ options on how to organize your app, with very little official guidance or recommendations from the Flutter team. For a beginner, this can create decision paralysis.
Having also done a lot of native mobile development, some of the IDE's features need to emulator their native counterparts. For example, trying to extract a string resource on Android in Xamarin Studio is painful. There are many useful tools in Android Studio that Xamarin should implement.
Xamarin will always be behind on native platform features. They must catch up when Apple and Google release new platform versions.
The biggest pain point is the random issues Xamarin continues to have. Having a large code base on top of a native platform makes it very difficult to debug issues. Every developer must decide if its an issue with Xamarin or the native platform. Bugs don't get fixed very quickly. Hopefully that will change with the Microsoft acquisition.
Xamarin has been great for developing different projects efficiently and effectively. It's nice to reuse the core business logic across different platforms so that there are less to maintain and little replications are needed. The biggest benefit is that C# programmers do not have to learn a different language to do mobile development.
If you are required to develop applications that are cross-platformed, Xamarin is a great tool to use. It will help save time and efforts from your development team to be able to build applications seamlessly for android, IOS, windows, and web on a single platform instead of requiring multiple tools to get the job done
I never had to contact support for any help. Most of the problems we ran into, we were able to identify and use peer support through blogs and other internet sources to resolve the problems. There are plenty of sources online which provide tutorials, discuss problems, etc. Example: StackOverflow
Just with any programming tasks, have a plan first. Design out the system, spend time to build it correctly the first time and have plenty of testing and user acceptance opportunities. Xamarin was easy to implement for a C# programmer. However, you need to do tutorials to realize the platform's capabilities.
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.
Xamarin runs natively on MacOS, and the debugger and other integration and auto-complete tools are far better than Eclipse for C# .NET. It also carries much of the plugin/add-on capabilities that are so desirable on Atom. Eclipse is a better for generalized software development, provided a developer is comfortable switching between the IDE the command line for certain parts of their workflow, like building, package management, or debugging. But for C# .NET development on MacOS specifically, Xamarin is the best product I've used for the job.
The rapid development capabilities of Flutter allow us to build apps we could not have previously considered commercially viable, opening new revenue streams.
Free and open licensing made adoption very easy (ie. free/low cost!).
In comparison to Qt, our time spent arguing with build tools and perfecting development environments has decreased substantially.
Code Sharing - We were able to launch an Android implementation of our app within weeks after finishing iOS. The amount of time taken to develop a new platform is very small.
Monetization - not the best, but definitely getting better. We've had issues with finding suitable ad networks that work with Xamarin.
