Flutter vs. React Native, which one should I choose?

The same as Flutter, React Native has many advantages and is widely used to develop cross-platform apps. This framework is based on a popular language, JavaScript, with which many developers are familiar, and its Hot reload function helps accelerate the development process significantly.

When it comes to finding the best cross-platform mobile app development, statistics may shed led on which one might be the right choice for you. Statista's data reveals that as many as 42% of developers chose React Native for their projects, while 39% of programmers prefer Flutter.

However, according to StackOverflow 2020 Survey, 68.8% of developers used Flutter in their development and expressed interest in continuing working with the technology, while 57.9% speak the same about React Native framework. Also, Google Trends shows Flutter as the market leader based on analysis of the last 12 months.

So while some figures may appear to bolster React Native, others speak in favor of Flutter. In cases like this, the best option will be to contact an experienced Flutter mobile application development company to help you choose the right tech stack and create your robust and modern app.

Is Flutter suitable for MVP development?

High competition and fast-changing consumer demands make companies present market-ready solutions more quickly than they used to. Luckily they can readjust and make it happen with minimum viable products. Flutter is precisely the right technology for MVP development as it allows building apps cost-effectively, accelerating the development process, and fascinating investors with beautiful UI designs.

So no matter if you are a startup making the first steps in business or a mature company creating your next big thing, make sure to find the right flutter development company (like Relevant) to help you reach your goals.

What are the benefits of the Flutter framework?

So why should you consider flutter app development services? Below, you will find a brief list of Flutter's benefits.

Fast development

By using a codebase that runs on all platforms, you can significantly shorten the time to market of your product. The modern architecture of the Flutter framework, its wide range of components, and its excellent support allow you to create an app very quickly, get it to market with no delays and verify your idea with potential users.

Great UI

Speaking of Flutter's advantages, it's hard to overlook an extensive collection of its pre-built UI components. The framework allows you to choose from a variety of widgets to accelerate development while ensuring that the style of your app is still aesthetically appealing and unique. It is also important to mention that Flutter's UI elements are highly customizable.

Hot reload function

One of the best features of the Flutter framework is probably its hot reload function. It allows flutter app developers to make changes to an application instantly while it's running. So you can reload the app's code and see the changes within seconds; you can find and fix issues in your application just as quickly; and what's more, this function helps you to enhance the collaboration between your programmers and designers as you can test your ideas for UI fast and make a decision for the best option easily.

High performance

Application performance is an essential factor that very much defines the success of your mobile app. And Flutter mobile app development services provide with an opportunity to eliminate the performance flaws and help build a truly powerful application.

So what factors do affect the performance of an app? These are CPU usage, average response time frame number per second, request number per second, and so on. Flutter framework offers you a consistent 60 fps, which is more than enough for modern screens to display a clear picture. Such performance helps Flutter to beat its competitors, such as React Native or Xamarin.Forms. Tests show that while a Xamarin app launches in 345 ms with a speed of 53 fps, a Flutter app launches in 220 ms with a velocity of 58 fps.

What is the cost of Flutter App Development Services?

The aggregated data shows that the flutter app development costs range between several thousand dollars to several hundred thousand dollars. There are at least a few things that explain such a difference. These are the functionality and complexity of a flutter application (therefore, the size of the team), the app design, plus, the QA and support and maintenance costs. One of the important is one of many predictors that defines the final price for flutter app development is the experience of the development team and the location of the flutter programmers.

So if you want to build a good flutter app, your job is to find that right team who is able to reach your expectations and budget requirements. In order to attain that, many entrepreneurs choose outsourcing software development to Eastern Europe. And many of them prefer Ukraine's outsourcing, not least due to its good quality-price ratio.

But are there any disadvantages of Flutter?

Flutter, like any other technology, comes with its own challenges. One of them is the large file sizes, which make developers go through great efforts to minimize the size of the code. To attain that, programmers often avoid animation, compress images, and reduce the number of packages and libraries.

Also, the fact that Flutter is a relatively young framework results in several issues. For example, there are not so many libraries that can be used in app development. What's more, there are not so many flutter programmers on the market because of the high demand. So if you've decided to hire one - contact us. As an experienced flutter app development company, we can find you the most relevant professional for your project!
