Cross-platform mobile app development allows you to build mobile applications for multiple platforms such as iOS and Android with just one technology stack.
This means that instead of creating multiple versions of your app, each written using the dedicated native language for each platform, you can write your code once and deploy it on several platforms at once.
There are several pros when it comes to cross-platform mobile app development compared to native mobile app development, including:
The most significant advantage of cross-platform development is having a single codebase that you can export to multiple operating systems.
Having a single shared codebase allows you to maintain the same look, feel, and experience across all platforms. All updates and fixes are also automatically reflected everywhere.
Instead of having separate teams with different skill sets working on multiple native versions of your app, you only need one team working on a shared codebase. This allows you to leverage smaller teams and quicker development time to save time and money.
Having your app published on multiple platforms allows you to increase your market reach without any added effort, consequently increasing your chances of getting more downloads and users.
While cross-platform development comes with many benefits that make it an optimal solution for many developers and companies, they come with a few drawbacks and some trade-offs including:
While cross-platform frameworks work on providing apps that are as close to native apps as possible, they still don’t integrate seamlessly with the respective platforms and have inconsistent communication between the native and non-native components, reducing the app’s speed and degrading performance.
Cross-platform development tools don’t have all the features offered by each different platform, so you might need to employ some workarounds. It may also take these frameworks some time to get up-to-date with the newest features and updates released by the platforms.
There are many native-only features and integrations available in each platform that are not available in cross-platform apps, which limits the user experience you can provide.
There are many cross-platform mobile app development tools and frameworks available, including:
We will take a closer look at the first and arguably most popular three frameworks available right now: Flutter, React Native, and Xamarin.
Flutter is an open-source, cross-platform mobile application development framework created by Google in 2017. It’s the newest framework of the three and in short order has become one of the most popular frameworks among front-end devs.
Some of the reasons Flutter is currently one of the most loved cross-platform frameworks include:
Flutter poses a few challenges, especially being a new framework, including:
However, you can always write your own native code that accesses the needed feature, and Flutter will give you a bridge to use that feature from within your Dart code.
React Native is an open-source, cross-platform mobile app development framework created by Facebook in 2015.
Some of the pros of React Native include:
Unfortunately, React Native still has its pitfalls, including:
Xamarin is an open-source, cross-platform mobile app development framework that was founded in 2011, making it the oldest of the three.
Xamarin cross-platform mobile app development pros include:
However, as any cross-platform development framework, Xamarin does have its setbacks, including:
Now let’s look at how these cross-platform development tools compare to each other.
One of the most important factors you should consider when choosing a cross-platform development framework is app performance.
While React Native and Xamarin provide near-native app performances, some argue that Flutter’s performance is better because Dart code is compiled to a C-library, which means it’s close to the native code.
This improves communication speed and provides better performance.
However, it’s hard to benchmark performance as it depends on many factors and variables including device, code, app, and features being used.
With over 1.6 million developers across 120 countries, Xamarin has definitely developed quite the userbase over the years. However, this is largely due to the fact that it is one of the oldest frameworks out there.
Since its release, React Native has slowly but surely gained popularity, surpassing Xamarin in 2017.
According to the Stack Overflow Developer Survey 2019, Flutter ranked as the most loved framework out of the three, with 75.4 percent of users expressing interest in continuing to develop with Flutter.
React Native came in second with 62.5 percent, followed by Xamarin with only 48.3 percent.
The cross-platform tool development language is another crucial factor to consider when making your decision.
Xamarin uses .Net languages like C# and F#, which are common languages and can be used to write native platform code.
As a result, some APIs might not work, while others may have to be proxied by React Native.
Flutter uses Dart, which was also not invented for mobile apps. However, it is managed by Google, the same company that created Flutter.
While still relatively new, Dart is ranked as the 26th most popular programming language in the world.
This gives an advantage to React Native and Xamarin, which both work with a familiar language that can help boost your productivity and save you from enduring a steep learning curve.
React Native offers some pre-built and partly adaptive components like buttons and text inputs.
However, most of these components aren’t really adaptive. If you need something a bit more advanced, you would have to build it yourself by recomposing these built-in components.
Flutter provides a more extensive library of components, which are called widgets. However, these pre-built components are non-adaptive.
The language offers widgets for both iOS and Android, but you have to switch between both manually as it doesn’t have components that automatically adjust their styles depending on the platform you’re running.
Xamarin.Forms offers a complete cross-platform UI toolkit consisting of native UI components for both platforms, which are compiled into platform-specific UI components.
You can also use Xamarin.iOS or Xamarin.Android for custom app UI and better performance.
Code reuse is what brings developers to cross-platform frameworks, so how much of the code written with each framework is actually reusable?
React Native allows you to write the code once and ship anywhere, but it also embraces platform differences.
This means that from time to time, you have to find out on which platform you’re running and load a different component or set of components depending on the platform you’re running.
Still, a considerable part of the codebase can still be reused.
Flutter’s codebase is more reusable as it allows you to define one UI widget tree and reuse the defined logic so you don’t have to do a lot of differentiation, which you can also still do if you need to.
Xamarin prides itself on allowing developers to reuse up to 96 percent of their C# code by leveraging the language.
Xamarin also offers forms components, making it better for code reuse than React Native and Flutter which share an average of 60–90 percent of codes.
While all three tools are free, open-source platforms, Xamarin is only free for individuals and small companies.
For large enterprises, single-user licenses start at $499 and go anywhere up to $2,999 for a Visual Studio Enterprise annual subscription.
While this might not be a problem for large enterprises, the costs can still add up, which could cause bigger companies to go with React Native or Flutter.
When choosing a framework, you should also consider its community support, especially if you’re new to it. This includes forums, documentation, tutorials, etc.
React Native has a pretty good amount of support out there. You can easily find a lot of learning material as well or developers on forums or QA sites like Stack Overflow to ask for support whenever you need any help.
Flutter is still relatively new, so it is yet to build a strong community like React Native. However, Google is investing heavily in it, and therefore it is expected to grow into a robust ecosystem in the future.
For Xamarin, support is quite limited. However, Microsoft provides some free Xamarin courses and learning paths to help you get started.
When choosing a cross-platform development tool, there is no one-size-fits-all option.
All three frameworks have proven successful in building great mobile apps. Your specific needs and preferences determine which framework is best for you.
Currently, Flutter seems to be the most popular option as it excels in terms of performance. So if you’re new to the world of cross-platform development, Flutter might be the way to go for you.
However, you can’t rule React Native and Xamarin out just yet as they still excel in other areas.
At the end of the day, it all depends on what you’re building and what you hope to achieve. Any framework will have its pitfalls, but the one where the advantages heavily outweigh those setbacks would probably be the right choice for you.

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Flutter Google cross-platform UI framework has released a new version 1.20 stable.
Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.
Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store. If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.
Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.
Here are the few key points of this release:
In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.
If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.
Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.
Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.
A new widget for interaction
InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.
In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with
DatePicker with support for date range and time picker with the new style.
Other than these widget updates there is some update within the project also like in
pubspec.yaml file format. If you are a flutter plugin publisher then your old
pubspec.yaml is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.
Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by
_dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.
The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.
Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the
There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.
