Xamarin vs Flutter; A Comparative Guide

Xamarin vs. Flutter 2020

What is the best framework to choose to build my app in 2020? Xamarin or Flutter? What are the main differences?

Before diving deep into this subject, let’s rewind a bit about the importance of mobile applications. Just think about this for a moment: What is something millennials can’t live without? Their phones! Nowadays, it’s weird to think of someone that doesn’t have a phone. Phones are replacing computers and laptops because we have everything in a small device that fits perfectly in our pockets – there are over 2.7 billion smartphone users across the world. The rise of smartphone users has led simultaneously to a significant increase in the number of mobile applications.

Companies are starting to feel the urge to develop their own business applications for many reasons. But creating a mobile app requires many important decisions. For instance, one of the most common dilemmas is choosing between building an app compatible with iOS or Android. And although some companies prefer choosing between these two, others decide to develop an application that runs in both. Is this even possible? We are living in a time where pretty much everything is possible! And the battle is choosing which framework is the best one to develop a cross-platform mobile application: Xamarin vs. Flutter 2020. 

Best Cross-Platform Development App Frameworks 2020

Cross-platform app development frameworks are the golden key for companies to create their business apps.  Instead of having to choose between developing an application only for Apple users or only for Android users, they can do both! 

The magic of these frameworks is that mobile developers can create applications compatible with more than one operating system. Here are the most popular cross-platform app frameworks of 2020:

Xamarin vs Flutter Comparison: Pros and Cons

Having the whole panorama of both frameworks will help mobile app devs to decide which one to use. Businesses can also determine what type of developer to hire: A Xamarin-oriented developer or a Flutter-oriented developer. 

Let’s take an overview of both frameworks, with their respective pros and cons.

Xamarin

Xamarin is a framework that helps in the development of cross-platform mobile applications. This open-source platform was founded in 2011, but Microsoft purchased it in 2016.

Xamarin offers a single language, C#, which works on three mobile platforms: Android, iOS, and Windows. It provides the option to reuse and share with these platforms while providing access to native APIs. Developers can build mobile apps that look and feel entirely native. 

This framework is one of the most used among developers due to all their advantages. But, is Xamarin the future of mobile development? Let’s analyze what the pros and cons of using the platform are:

Xamarin Pros

1. Performance

Xamarin is popular mainly because it offers developers features that make the app run as if it was native. This means that Xamarin developers can build Android and iOS applications despite their entirely different operating systems. 

2. Scalability

Another characteristic that makes Xamarin applications have excellent performance is that developers can test how the application is running.  With Xamarin Insights, it’s easy to detect if an app has any bugs or errors. It offers a real-time app monitoring feature to make sure everything in the app is running efficiently. 

3. Xamarin.Forms

Xamarin.Forms are a huge advantage for developers. It’s a cross-platform UI toolkit that makes the job easier for a developer who wants to create UI layouts shared across multiple platforms.  Some of them even choose to use this framework rather than using Xamarin Native for many reasons. For instance, with Xamarin. Forms developers don’t need to learn all the native UI frameworks and can design views quicker. 

4. Supports libraries

Imagine having a deadline for tomorrow about a topic you have no idea about. What is the first thing that comes into your mind? Google! Think about these libraries as you think of Google: the solution to everything. And Xamarin gains another golden star because of its ability to use a variety of libraries. Xamarin lets developers implement the most complicated functionality without having to pour sweat (or tears).

Xamarin Cons

1. Knowledge of native languages

If you are a developer, you should know that using Xamarin requires that you know the fundamental aspects of the operating systems you are trying to develop the app for. Although you don’t need to be an expert, you should know the programming languages used in the systems. For example, if you want to build a cross-platform app for Android and iOS, you need to have the basic knowledge of Java and Kotlin (Android) and Swift, Objective-C (iOS). 

2. Large App Size

This depends on the type of application you are trying to build. But overall, Xamarin apps are larger than native ones. The size may range from 5MB to 20MB.

3. Not suitable for complex applications

Xamarin is efficient when it comes to building apps with a simple UI. However, when developers have to create an application with complex animations, or heavy graphics, Xamarin might not be the best option because it consumes a lot of the developers time because they have to write many specific codes. 

4. Smaller community 

The Xamarin community is smaller than the native iOS and Android communities. This means that finding an experienced Xamarin developer can be challenging, especially if you have a hard time headhunting talented developers.

Also, because the community is smaller. Some developers might have a hard time learning and finding support whenever they are facing problems. Yet, the platform provides extensive support, and it even has an educational platform: Xamarin University. 

Flutter 

Flutter is an open-source mobile UI framework created by Google and released in 2017. This framework allows developers to create a native mobile application with only one codebase. Developers can use one programming language, and the same codebase two create apps that work on different operating systems.

This Framework uses Dart as its programming language.

Flutter has two important aspects:

1)    A Software Development Kit (SDK): It’s a collection of tools that help developers build applications. (tools that help transform code into native machine code)

2)    A Framework (UI Library): It’s a collection of reusable UI elements that help developers personalize their needs for the app.

Let’s analyze the pros and cons of Flutter:

Flutter Pros

1. Fast Development

Flutter is one of the fastest cross-platform frameworks. It allows developers to use the same code base and build separate iOS and Android apps. This means that the application’s development process is speedy, and development teams don’t need to waste time working on the code for a single platform. 

2. Great for startups

Flutter is a great tool to use for your minimum viable product. It’s cheaper to develop mobile apps because, as stated previously, one code developer can create and maintain an application in different operating systems.  Plus, you don’t need to hire a team of IT experts to build your app, with one developer who understands Flutter is more than enough to create your MVP.

3. Hot Reload feature

This feature makes it possible to make changes to the code and see the results (live) in the app preview. It also helps developers experiment, build UIs, add features and fix errors. 

4. Beautiful design

Two powerful characteristics of Flutter are the excellent programming language (Dart) and a fast performance rendering engine (Skia).  This makes the platform help developers create applications with design patterns and best practices. Flutter provides beautiful and customizable widgets making the developers build apps that look great! 

Flutter Cons

1. It’s still an immature framework

Flutter is still new, which means that it still has a few errors regarding its stability. Some users also claim that there’s a lack of advanced features that support operating systems capabilities.  

2. Managing new system features

Whenever iOS or Android introduces new features to their operating systems, these will reflect later in Flutter than in their native software development kits.

3. Limited libraries

Flutter receives Google’s constant support, and many libraries help developers whenever they need to implement specific functionalities. However, because Flutter is still a new framework, not every function is available in these libraries. Ultimately, if a developer needs a specific functionality, they will need to build them by themselves.

4. Large file size

One of the major disadvantages is the large size that the apps developed with Flutter have. When apps take a lot of memory space in a mobile, users tend to be more selective. And although there are phones that have enough capacity to store the app, this is not the case for all of them. Older devices, or even new ones, sometimes don’t have much space, and users have to decide if it’s worth deleting an app to download the new one.

Who Wins the Xamarin vs Flutter Battle?

What is the verdict? Which one of these frameworks is the best one for cross-platform mobile applications?

The answer is…both! Both are excellent for developing applications!

It depends on your priorities and the aspects you consider your application should have or how it should perform.  In general terms, Flutter is more popular than Xamarin. A vast number of developers instead use Flutter because of its features and because although it’s still new, it keeps improving. But if you prioritize the aspects that Xamarin is stronger at, Xamarin is your option to go.

Our advice is to look at the characteristics you prioritize more and see which of both frameworks covers those priorities. Then you could get into looking for a developer who can build the application for you.
