Planning for responsive development in 2021? Not sure which technology you should choose to develop your application quickly and at a lower cost? If you answer yes to both questions, you will have two main choices: Flutter or React Native!

But again, which technology is the best choice for cross-platform application development is still a headache for you!

Although there is a wealth of information on the Internet that can explain to you the basics, pros and cons of each technology. But how will you compare all these advantages and disadvantages to determine which technology best suits your application development needs?

With my experience with both technologies, I can help you distinguish between the two most popular and commonly used technologies when building cross-platform mobile applications.

It’s 2021, and the impact of the pandemic has led to a surge in demand for mobile apps.

The urgent need for enterprises to create a fast mobile application in order to provide comprehensive and customized solutions for individual customers is driving them to look for cross-platform application development solutions. But why not native iOS and Android apps?

Due to the time and cost of native application development, the concept of cross-platform application development has grown in recent years and the demand for cross-platform application development companies has increased. In the past few years, Flutter/React Native has become the most popular buzzword in the community.

Cross-platform applications use the same code base to create applications that can run seamlessly on multiple platforms, making development faster. However, different cross-platform application development frameworks offer different features and benefits. So, drawing on my app development experience with Flutter and React Native, I’m trying to compare these leading technologies or frameworks to help you understand what options are right for your needs in what situations.

Flutter VS React Native: side by side comparison

Before you jump right into the Flutter vs. React Native comparison, it’s worth knowing that both frameworks are top picks for building cross-platform mobile apps. But sometimes making the right decision is constrained by the perspective the organization uses.

So, here are some important parameters that I chose to compare:

  • Flutter Vs React Native: Who supports Flutter?
  • Flutter Vs React Native: Actual statistical market share
  • Flutter Vs React Native: favorite and popular
  • Flutter Vs React Native: Dart Vs JavaScript
  • Flutter Vs React Native: Technology Architecture
  • Flutter VS React Native: performance
  • Flutter VS React Native: Easy to adopt and community support
  • Flutter Vs React Native: UI components and customizations
  • Flutter VS React Native: Code maintainability
  • Flutter VS React Native: Developer cost per hour
  • Infographic comparisons to make final decisions
  • Conclusion, the winner of the game!

Let’s get started and look at each point in detail!

1. Flutter VS React Native: Who supports Flutter?

Bottom line: Both frameworks were created and supported by the industry’s biggest tech giants, Google and Facebook, so both will continue to exist in the future.

Google’s baby, Flutter, launched in 2017, is an advanced app software development kit (SDK) made up of all the gadgets and tools to make your development process easier and simpler. A wide selection of widgets enables developers to build and deploy visually appealing, native-compiled applications for multiple platforms, including mobile, web, and desktop, in a simple way, using a single code base. Therefore, Flutter Application Development company has a better chance of ensuring your application development solution is faster, faster and reliable. But to what extent is that true? Let’s evaluate it in terms of its characteristics.

Here are the quick selling points of Flutter:

  • It is free and open source.
  • The architecture is based on popular Reactive programming because it follows the same style as Reactive.
  • Thanks to the widget experience, the Flutter application has a pleasant UI that can be transformed into an application that looks and feels great.

React Native is also a cross-platform Native mobile application development framework launched by Facebook in 2015. React Native mainly uses JavaScript, which is handy for developing apps for iOS and Android using the same code base. In addition, its code-sharing capabilities lead to faster development and reduced development time. Like other cross-platform technologies, Flutter allows you to build separate applications using the same code base, so React Native apps are easier to maintain.

Let’s take a quick look at React Native’s features:

  • React Native includes a hot-reload feature that speeds up the development process by allowing developers to add or correct code directly to a running application without having to save the application.
  • React Native is based on a very popular language, JavaScript, that many developers are already familiar with.
  • The React component wraps existing native code and interacts with native apis through the React declarative UI paradigm and JavaScript. React Native’s feature allows developers to work faster.

Flutter VS React Native: Actual statistical market share

Conclusion: When summing up the best cross-platform mobile app development frameworks used by software development companies around the world in 2019 and 2020, 42% of developers preferred to stay with React Native, while 39% chose Flutter.

But different market reports have different statistics. But before you start hiring app developers, it’s important to evaluate real market data in order to make an informed decision.

According to StackOverFlow, 68.8% of developers prefer to use Flutter for future development projects, while 57.9% prefer to use React Native technology for application development.

According to the market trend 2: * * * * [Google Trends] (… Native), in the past 12 months, Flutter has led the market and beaten React Native.

Despite being a young framework, Flutter has 168,000 members and 118K stars on Github. React Native has 20.7k forks and 94.6 K stars.

3. Flutter VS React Native: the most loved and welcomed frame

Bottom line: Both are young cross-platform application development frameworks backed by Google and Facebook, and both will grow in popularity over time. But if you consider the same Github repository survey in 2019, Flutter has gained momentum with 11.8k stars, surpassing React Native with 94.6k stars.

React Native has become the choice of 42% of developers worldwide, and 39% of developers are using Flutter in 2020, according to Statista. However, if you compare the growth of the two frameworks, Flutter has jumped from 30% to 39% of developers in one year and is expected to dominate the industry in the near future.

4. Flutter VS React Native: Dart VS JavaScript

Conclusion: Flutter is based on Dart, while JavaScript used by React Native has dominated the IT industry for a long time and plays an important role in the back-end development process. But that doesn’t mean you underestimate the programming language of Flutter. Let’s learn!

Which is best for Mobile app development in 2021, Flutter Vs React Native? This is one of the most common problems among developers. The choice of framework depends largely on the programming language the technology is based on, as you will need to further evaluate the complexity or flexibility of that programming language in order to continue using it.

Dart is a relatively new language introduced in 2011. However, as Google’s internal programming language, there is plenty of room for it to continue. Moreover, because it is a new programming language, cross-platform application development companies can take advantage of its modernity in application development solutions.

Second, the language is twice as fast as JavaScript and has AOT and JIT compilers. In the case of flutter, you need to hire application developers who are familiar with Java or C++. But from another perspective, JavaScript is one of the most popular languages in the developer community developing React Native mobile apps. So if anyone already knows JavaScript, they can easily learn React and start developing applications.

5. Flutter VS React Native: Technology architecture

Conclusion: If technically speaking, Flutter is an advanced SDK that provides a layered architecture to ensure a high degree of customization, where React Native relies on other software to build reaction components and uses JavaScript to connect Native modules. Bridges affect performance even when minor changes are made, and Flutter can manage everything without Bridges.

Flutter has a layered architecture that paves the way for quick and easy UI customization. It is believed to give you complete control over every pixel on the screen and give mobile app development companies unlimited integration of overlay and animated graphics, text, video and controls.

Performance and technology architecture are the biggest issues for organizations evaluating business growth and further application scalability when comparing the advantages and disadvantages of Flutter Vs React Native.

6. Flutter VS React Native

Bottom line: When questioning yourself about which framework is right for you, performance may be your biggest decision driver in 2021. The Flutter has an advantage over React Native when comparing the performance of frameworks.

Whether you’re starting with AN MVP or an advanced app structure, it always makes sense to choose to hire a mobile app developer whose skills can ensure you get high performance in this booming industry.

On the technical side, Flutter compiles to ARM or x86 native libraries, which makes it faster and adds an advantage. React Native, on the other hand, is not compiled into machine code and still has a JavaScript layer, which makes it perform less well than Flutter.

7. Flutter VS React Native: Easy to adopt and community support

Bottom line: Community support is a factor that must be examined when it comes to building enterprise applications. React Native and Flutter have been in the industry for years and have the latest technological updates.

With each incremental release and technical update, community interest in and demand for the framework grows. Let’s take a look at how these two frameworks stand in terms of community engagement.

React Native launched in 2015, and its community has been growing, as evidenced by the number of contributors to the framework on Github. But while Flutter is young and relatively new, it is fast taking over the industry.

Flutter Vs React Native: UI components and customizations

Conclusion: Because Flutter has its own set of UI components and widgets, while React Native only provides a basic widget box, Flutter offers better UI customization and makes it consistent across platforms.

Since the launch of the framework, Flutter has been known for its beautiful, native-like widgets rendered and managed by the framework’s graphics engine.

In addition, it is designed to support Material Design and is out of the box. All you need to do is hire application developers who have excellent skills with Flutter and can easily customize the needs of the project with prefabricated Widgets to create most views.

React Native, on the other hand, provides basic tools to adapt to the platform, such as buttons, sliders, load indicators, and so on. React Native has a number of third-party components that can help you customize your app’s UI.

9. Flutter VS React Native: Code maintainability

Bottom line: No matter how great your application is, it must be upgraded and debugged to keep it running smoothly and continuously. Using React Native maintenance code is really difficult compared to Flutter.

In React Native, when you fork code to fit your application, it interferes with the framework’s logic, slowing down the development process. In addition, most of the Native components in React Native applications have third-party library dependencies, so maintaining those out-of-date libraries can be a daunting task.

In the case of Flutter, it was much easier to maintain the code because the simplicity of the code made it easy for mobile application developers to spot problems, find external tools and support third-party libraries.

In addition, the time required to publish high-quality updates and make immediate changes in the application performed better in Flutter than with React Native’s thermal overload capability.

10. Flutter VS React Native: Developer cost per hour

Bottom line: Whether you’re a startup or a leading entrepreneur, developer cost per hour is always your number one concern. So when you choose to hire a local development company or A Flutter application engineer, you may want to know their rates, and different locations will offer you different hourly rates. Let’s check!

When hiring application developers, whether Flutter or React Native, there are many factors to consider, such as experience, expertise, project handling, and so on, in order to assess the actual hourly cost of the developer.

When hiring app developers, whether Flutter or React Native, there are many factors to consider, such as experience, expertise, project handling, etc., to assess the developer’s actual hourly cost. But of all these factors, the location of the developer is the most important and can make a huge difference in hourly costs.

Region/region Flutter React Native
In Western Europe The $80 + per hour $50 + / hour
India $18 + / hour $15 + / hour
The united Arab emirates $22 + / hour $18 + / hour
The United States The $75 + per hour The $65 + per hour

If you’re still not sure when to choose Flutter or React Native for your development project, it’s best to take a quick look at the chart comparison between Flutter Vs and React Native:

Flutter React Native
A programming language Dart JavasScript
Basic knowledge needed to get started C # or Java Front-end development (JavaScript)
The technical architecture Use its own widget library to display the Flutter UI Connect to the UI thread via the React Native bridge
Off-the-shelf UI widgets and components Huge library of plug-ins and widgets Use the operating system’s native UI components
Development tools and documentation Excellent documentation and starter kit Extensive documentation and tutorials. Developing from scratch is not easy
When selecting The App UI is a priority if you want to create an App that runs between 60 and 120 frames per second You want common code for mobile, Web, and desktop
Do not select if Your application should be less than 4MB You are looking for heavily enterprise-class applications
Use case Google Ads, Alibaba, Reflectly, My Leaf, Groupon, Topline Facebook, Instagram, Skype, Airbnb, Walmart, Pinterest, Tesla
The development of Simple, built-in library Third-party library support is required


Flutter and React Native are both dominant technologies when developing cross-platform applications because they both have special features such as real-time refreshing or building graphical UIs using adaptive software. The choice of framework depends largely on the needs of the project, with different project types requiring different advantages. So declaring a winner means going beyond one lead frame over another, which really doesn’t make any sense.

In addition, you can work with a mobile application development company to analyze your project requirements and seek valuable advice from expert programmers before choosing any framework for your project. They bring the best of their expertise to the project and enable you to build the application using the most appropriate methods. So don’t waste your energy weighing frameworks, because the experts have the best knowledge to implement the right technology for the project requirements.
