Planning to go responsive in 2021? But not sure which technology you should choose to get your application quickly developed and that too at a reduced cost? If yes will be your answer to both the questions then you will be left with two major options Flutter or React Native! But again, which is the best choice of technology for cross-platform app development will remain a burgeoning question to you! While there is a huge amount of information available on the internet that may explain to you the basics, pros and cons of each technology. But how will you compare all those pros and cons on the same note to decide which is the best choice of technology that matches your app development needs? A big problem! With an experience of working with both of these technologies, I can help you draw a line between these two most popular and used technologies to build cross-platform mobile applications. It’s 2021 and the impact of the pandemic has caused the surging demand for mobile apps. According to the survey reports, the mobile apps have generated $581.9 billion revenue and expected to generate $935 billion in by 2023.” With this statistical analytics, businesses from all verticals are carving out space for themselves in the mobile phones of the users. The urgency among businesses to create a quick mobile app in order to cater the comprehensive and customized solution to the individual customer has pushed them to look for cross-platform app development solutions. But, Why not native iOS and Android apps? Since native apps are quite time-consuming and cost-intensive to develop, therefore the concept of cross-platform app development has gained momentum in recent years and the demand for cross-platform app development companies has been increased. And Flutter/React native has outshined as the community’s favourite buzzword over the last few years. Cross-platform applications are faster to develop as it uses the same codebase for creating applications that can seamlessly run on multiple platforms. But different cross-platform app development frameworks offer a different set of features and benefits. So, leveraging my experience in app development with Flutter and React Native, I’ve tried to compare these leading technologies or frameworks on common notes to help you understand what option will suit your needs under what situation. Flutter Vs React Native: Side-By-Side Comparison Before you drill straight into the Flutter Vs React Native comparison, it is worth knowing that both frameworks are the top picks for building cross-platform mobile applications. But sometimes making the right decision is subject to the matter of perspective of the usage of the business. So here are a few important parameters that I have chosen for the comparison:
Let’s start one-by-one and understand each point in detail!

1. Flutter Vs React Native: Backed by Whom?

Conclusion: Both of these frameworks are made and backed by the biggest tech giants of the industry Google and Facebook respectively, so both will stay in future. Google’s baby, Flutter introduced in 2017, is an advanced app software development kit (SDK) consisting of all the widgets and tools to make your development process easier and simpler. The wide choice of widgets allow developers an easy way to build and deploy visually attractive, natively-compiled applications for multiple platforms including mobile, web and desktop all using a single codebase. Therefore, there are better chances that Flutter app development companies can ensure you faster, quicker and reliable app development solutions. But how far is this statement true? Let’s evaluate it with its features.
Here are quick selling points of Flutter:
React Native is also a cross-platform native mobile app development framework launched by Facebook in 2015. React Native mainly uses JavaScript and comes in handy for developing applications for both iOS and Android with the same codebase. Further, its code sharing features lead to faster development and reduce development time. Like any other cross-platform technology, Flutter allows you to use the same code base for building separate applications therefore, react Native applications are easier to maintain.
Let’s have a quick glance over the features of React Native:

2: Flutter Vs React Native: Market Share With Real Statistics

Conclusion: When it comes to concluding the best cross-platform mobile app development frameworks used by software development companies worldwide in 2019 and 2020, it results in 42% of developers prefer staying with React Native whereas 39% of developers have chosen Flutter. Market Trend #1: According to StackOverFlow, 68.8% of developers loved using Flutter for further development projects whereas 57.9% of developers are further showing interest in using React Native technology for app development. Market Trend #2: According to Google Trends, with over the past 12 months analytics, Flutter is leading the market and defeating behind React Native. Market Trend #3: Despite being a young framework, Flutter has a community of 16.8K members with 118k stars on Github. Whereas React Native has 20.7k Fork and 94.6k stars. But different market reports have different stats to reveal you. But before you start searching to hire flutter app developers, it is worth evaluating the real market stats to make an informed decision.

Coming to the other side of the story, according to Statista, React Native is already a choice of 42% of global developers whereas 39% of developers are using Flutter in 2020. But if you compare the growth of both the frameworks then Flutter has taken a steep jump from 30% to 39% of developers in a year and expected to dominate the industry in near future.

4. Flutter Vs React Native: Dart Vs JavaScript

Conclusion: Flutter is based on Dart while React Native uses JavaScript that is already ruling the IT industry for a long time and catering an important role in the backend development process. But it doesn’t mean you underestimate Flutter’s programming language. Let’s learn how! Flutter Vs React Native, which is best for mobile app development in 2021? It is one of the most common questions among developers. The choice of framework majorly depends upon the programming language that technology is based on as you need to further evaluate how complicated or flexible that programming language is to proceed with. Dart is a much newer language that was launched in 2011. But being Google’s in-house programming language, it has a great scope to stay in use further. In addition, as it’s a new programming language, so cross-platform app development companies can leverage its modernity in app development solutions. Secondly, the language is up to two times faster than JavaScript with both an ahead-of-time (AOT) and just-in-time (JIT) compiler. In case of flutter, you need to hire app developers, who have familiarity with Java or C++. But coming to the other side, JavaScript is one the most popular languages in the developer’s community for React Native Mobile app development. So if anyone who is known to JavaScript already can easily learn React and get started with app development.

5. Flutter Vs React Native: Technology Architecture

Conclusion: If technically speaking, Flutter is an advanced SDK that provides a layered architecture to ensure high customisation where React Native depends on other software for building react components and uses JavaScript to bridge the connection to native modules. The bridge affects the performance even if slight changes are taken place whereas Flutter can manage everything without a bridge. Flutter has a layered architecture that paves the way for easy and quick UI customisation. It’s believed to give you complete control over every pixel on the screen and allow mobile app development companies to integrate overlay and animate graphics, text, video and controls without any limits. While comparing the pros and cons of the Flutter Vs React Native, performance and technical architecture are the biggest concerns of the organization to evaluate the business growth and further scalability of the application.

6. Flutter Vs React Native: Performance

Conclusion: When questioning yourself, which framework is right for you, then performance can be the biggest decision driven factor for you in 2021. And Flutter has the upper hand over React Native when comparing the frameworks on performance. No matter, whether you are starting with MVP or an advanced level of app structure, it always makes sense to choose to hire a mobile app developer that works in technologies that ensure high performance to make you win in this thriving industry. In technology terms, Flutter is compiled to ARM or x86 native libraries, which makes it considerably faster and adds an edge over others. On the other hand, React Native is not compiled to native code and still has the JavaScript layer which makes it less performant than Flutter.

7. Flutter Vs React Native: Ease of Adoption and Community Support

Conclusion: When it comes to building enterprise applications, community support is the must check factor. And being both React Native and Flutter are evolving in the industry for years and come up with the latest technological update. And with each incremental version and technological update, the interest and demand for the framework gradually increase in the community. Let’s understand how things are between both frameworks when it comes to community engagement. React Native, being launched in 2015, its community has been at a growing stage and the number of contributors to the Framework on Github is proof of that. But despite being young and newer, Flutter is quickly taking over the industry.

8. Flutter Vs React Native: UI Components and Customization

Conclusion: Since Flutter comes up with its own set of UI components and widgets whereas React Native provides only a basic box of widgets, therefore, Flutter offers better UI customization and makes it cross-platform consistent. Right from the launch of the framework, Flutter is known for its beautiful UI native-like widgets that are rendered and managed by the framework’s graphics engine. In addition, it is designed to support material design that is out of the box. All you need is to hire app developers that have excellent skills in using Flutter to create the most of the views with pre-made widgets which are easily tailored to the needs of the project. On the other hand, React native provides the basic tools which are adaptive to a platform, like a button, slider, loading indicator and more. But there are a lot of 3rd party components available for React Native that can help you customize the delightful UI of the app.

9. Flutter Vs React Native: Code Maintainability

Conclusion: No matter how brilliant an app you have developed, to make it run smoothly, constant and upgrading and debugging is necessary. And maintaining codes with React Native is really tough as compared to Flutter. In React Native, when you fork the code to suit your application, it interferes with the framework’s logic thereby slowing down the development process. Also, in React Native applications, most of the native components have a third-party library dependency so maintaining those outdated libraries is really a challenging task. In the case of Flutter, maintaining codes is much easier due to the simplicity of the code that allows mobile app developers to easily spot issues, source external tools and support-third party libraries. In addition, the time taken for releasing quality updates and making immediate changes in the app are performed better in Flutter than using a Hot Reload capacity of React Native.

10. Flutter Vs React Native: Hourly Cost of Developer

Conclusion: Whether you are a startup or a leading entrepreneur, the hourly cost of the developer is always a serious concern for you. So when you choose to hire a react native dev company or Flutter app engineers, you would probably want to know their rates and different locations have different hourly rates to offer you. Let’s check! When it comes to hiring app developers whether it be for Flutter or React Native, there are a number of things to consider such as experience, expertise, project handling, and more to evaluate the actual hourly cost of the developer. But among all, the location of the developer is the most important factor that can bring a huge variation in the hourly cost.
