React Native vs Flutter-Which One To Choose?

Developers keep discussing the trending technology and React Native vs Flutter is the talk of the town now. As the demands of application increases, there’s mounting pressure on enterprises, entrepreneurs and even start-ups to focus more on the Mobile app development.

At the same time, there has been plenty of new technologies which help both users and service providers to optimize services, based on the user demands.

But, these freedom is provided by the app development platforms.

There are various development platforms available for developers to create or build mobile applications, even for cross-platform apps.


React Native, launched in 2015, has been into the limelight for allowing developers to create cross-platform apps for both major platforms such as Android and iOS.

However, the top tech giant Google came following Facebook’s React Native and launched its much-hyped cross-platform framework -Flutter in 2017.

After going through various experimental and improvement porcess, it has launched the sixth and final version of Flutter Preview 2 which will be followed by the stable version of Flutter 1.0.

Update: Google finally come up with much awaited Flutter 1.0 release. Cheer up for developers who are looking for stable release.

That resulted in tough competition between the two top frameworks -Flutter and React Native. Now developers are actually puzzled with the two frameworks thinking which one to choose.

So, we have found out solutions to provide you with the comprehensive ideas of the two platforms so that you can easily find their significance and imply as per your usability.

What is React Native?

React Native is Facebook inventory which offers developers to create cross-platform applications for both Android and iOS device.

It’s a JavaScript Framework that supports real-time Android and iOS applications with native rendering approach.

React Native came offering an alternative to developers who were struggling to develop apps using Android Studio for Android and XCode of iOS.

What is Flutter?

Flutter is developed by Google and its first preview 1 released 2017 and get large user attention across the world. The mobile app SDK offers to create high quality and extremely fast application which can run on both Android and iOS devices.

React native uses JavaScript language to write while Flutter uses Dart for the same. However, it has a thin layer of C/C++ code which developers can easily approach and also provides complete control over the system.

Let’s take a look at the quick overview of the two Cross-Platform frameworks React Native Vs Flutter;


React Native


Initial Release

It was initially released in 2015 Flutter’s first Preview released in 2017

UI Components

Based on Proprietary Widgets Based on Native Components


It uses JavaScript Flutter uses Dart language


React Native works Faster It’s a bit slower than React Native

Configuration Setup

Provides no streamlined setup and Configuration Flutter offers compact and straightforward Conf. Setup

App Performance

Performance is a bit slow due to interaction initiated through JavaScript bridge Extremely fast due to interaction initiation is higher at 60fps animation standard.


React Native incorporates the bulk of IDESs & tools. Flutter has compatibility with IntelliJ Idea, Visual Code Studio and Android Studio

Code Structure

Code Structure direct with React Native as it uses JavaScript It is messier with Flutter as it has a separation between templates, styling and data in the file

Stateful Hot Reloading

React Native offers hot reloading Flutter also offers hot reloading

Native Look & Feel

Less due to dependency on third-party apps Better due to access to device’s core functionality

Hardware Specific APIs

It has supporting API to specific hardware Flutter too has supportive APIs for specific hardware


It’s a bit disorganized and clumsy Flutter offers regimented and smooth documentation


Has large community support It is new, so it has not so strong community support

Let’s compare React Native vs Flutter based on these below mentioned features

react native vs flutter Comparision Points

1. Performance

Both React Native and Flutter provide the awesome performance to users. But there are some areas where developers may find an edge between the two. Some may like React Native while some may choose Flutter to work with. Let get more clear insight through the comparison right here.

React Native:

React native works excellently when you choose to build native apps. You are not going to face any problem regarding its performance. You will get standard and reliable performance, no doubt. But, the issue begins with when you build a hybrid app. You may face a problem with its architecture, libraries and native components.


Well, as far as Flutter is concerned, you get everything customised right of your choice. Developers can use the same existing code to develop applications. Importantly, Flutter is helpful in this context as it is backed by the Powerful C++ engine.

My View: Honestly speaking Flutter has the edge over React Native here. But, developers may choose the framework as per their comfort of use or requirement.

2. User Interface

Creating a quality user interface does matter and developers especially eye on the UI feature while selecting the development frameworks. Just go through the comparison given here.

React Native:

When it comes to finding ‘User Interface,’ React Native is based on the native components. Building blocks for user interface become quite easy and an Expert React Native Developers may provide the best results using the React Native components.


Here’s, developers meet a completely new and different scenario as building blocks and creating an excellent user interface. With Flutter, developers can build quality and fully customised UI designs with additional native support. But, it faces some problems while creating UI for iOS.

My View: Both are good here, but if you have quality demand for iOS UI, then opt for React Native.

3. Development Time

On time delivery of the project, this is what has been promised by every company while taking a project. This is, in fact, based on the capacity of frameworks -not the workforce (to some point). Yes, there are plenty of frameworks providing cross-platform application but only a few stands by the promise and they are everyone’s favourite React Native and Flutter (Flutter is working well, but still, it is new). So, let’s find out which one serves you well as far as development time is concerned.

React Native:

React Native offers ready-to-use components and you get more exceptional supports as it creates not issue and help developers build a faster landscape of mobile applications.


As the Flutter is new and it still under development process (as a stable version for Flutter 1.0 yet to be released), it takes a bit longer time to complete your project. It offers better usability, but as far as development time is concerned, it requires more improvement.

My View: Development time is an important factor to look into. However, if you have projects which are abided by any time-bound, you are free to choose any platform you want. However, if you have to finish the project within the time-frame, then will suggest working with React Native.

4. Stability

Stability is one of the biggest things to look into when it comes to choosing the right frameworks. Being a trusted mobile app development company, you need to opt for such frameworks which offer improved stability.

React Native:

React native old and trusted framework which is supported by a large community and therefore very famous among developers. It is stable since its launch and helps developers to provide stable cross-platform apps quickly.


Flutter is new and available in beta version only. Therefore, developers need to wait till the tech giant launches the stable version ‘Flutter 1.0. However, the recently released Flutter Preview 2 offers more tools to developers.

My View: To me React Native steals the show here due to its maturity in the industry.

5. Clientele

Having a large number of clients entirely depends on the quality service, reliability and stability. So, you need to find which one from the two -React Native and Flutter surpasses the criteria.

React Native:

React Native is new and has been in the market for a long time. So, there is no doubt that it has the edge over Flutter. There are some big brands which are the most trusted clients to React Native which include, Skype, Facebook, Tesla, Airbnb, Instagram, Walmart, etc.


As far as Clientele of Flutter is concerned,  it is new yet have some valuable clients such as Alibaba, Nubank, Live Quiz and much more4. These websites are not entirely dependent on Flutter, but they have started using it gradually. Besides, as the technology is new, the Flutter also trying with all its means to make its presence felt in the market and tech industry.

My View: Again React Native rules roost due to the advanced maturity level.

6. Documentation & Toolkit

Frameworks with quality documentation and toolkits are impressive. Let’s check out gets more score out of the two here. It developers to know the right structure, architecture, find the code easily.

React Native:

React Native has documentation, but it’s a bit disorganised and clumsy. So, developers have to put a bit extra efforts to look for the new architecture.


While Flutter has more organised documentation and offers extensive IDE which are the best option developers to get things done in fewer efforts.

My View: Here Flutter wins the Race.

Both React native and Flutter holds some exceptional quality in respective fields. But, while going through the topic, one can say that React Native is a bit friendly than Flutter.

The reason, Flutter is extremely new and still going through under development process. The final version of the framework yet to come. Therefore, it will be immature to get a final conclusion that React Native will remain the best forever. It may be changed.
