In this article, will we teach about React Native vs Flutter which one is the better.

About React Native

React Native is an open-source mobile application framework created by Facebook, released in March of 2015. It's used for both mobile and web applications, by enabling developers to use React and other native platform capabilities. Being built on top of ReactJS and Javascript, it's likely that developers that are used to such languages may find a preference for React Native over other frameworks.


About Flutter

Flutter is an open-source UI software development kit created by Google, released in May of 2017. It's used for both mobile, desktop and web applications, all from the same codebase. Based on the object-oriented programming language Dart, those with a preference for those types of paradigms may prefer Flutter.

While Flutter comes with its material design guidelines, one may be inclined to use it. However, there's no inherent problem with not using it, as Flutter was created with a custom brand design in mind. It just happens to have some material design as a bonus.


Which one is more popular: React Native or Flutter?

To give you a few experiences on how famous the two systems are, here's a realistic showing the quantity of inquiries on StackOverflow that React Native has contrasted with Flutter.As should be obvious, Flutter quickly acquired foothold, particularly beginning around 2018, in a way that since the finish of 2019, StackOverflow has had a larger number of inquiries posed with regards to Flutter than React Native. Shudder turned out to be somewhat more well known as Google has been putting a great deal of time into it.

Is React Native easy to learn?

Since it comes from JavaScript, it's more straightforward to learn and investigate than different dialects. It implies you have a more direct way to deal with advancement. In any case, that simplicity comes at the expense of numerous mistakes individuals might find in their code, in runtime, in light of the fact that JavaScript is certifiably not a severe language. To keep away from this, Facebook, React Native's maker, recommends Flow, a sort checker. It permits the consideration of comments on JavaScript to gather types and recognize unfortunate conduct, that is utilized to relieve this issue by distinguishing issues as the code is being composed.

Is Flutter easy to learn?

In a vacuum, Flutter is not as easy to learn as React Native. Nevertheless, a background in either Dart or any other Object-Oriented Language will make your life easier. Due to its increase in popularity, finding help online is quickly done and hardly any trouble.

React Native vs Flutter: key differences


How does React Native work?

React Native offers components equivalent to React’s web counterpart. Span in React is Text in React Native, which would be equivalent to UIView in iOS and TextView in Android.

Two threads are intrinsic to each React Native application:

  1. The main thread runs a standard native app, handling the display of elements and processing user gestures.
  2. The other executes all the JavaScript code in a separate engine, either JavaScriptCore or V8, which deals with the business logic of the application. It also defines the functionality and structure of the user interface.

These threads never communicate directly or block each other.

How does Flutter work?

What could be compared to iOS's UIView and Android's View, in Flutter, is a Widget, which is fairly not quite the same as the partners referenced previously. First off, they have an alternate life expectancy: they are unchanging and just exist until they should be changed. At the point when that occurs, Flutter's system will make another arrangement of gadget cases. In examination, sees in iOS and Android are drawn once and just redrawn when setNeedsDisplay() and discredit, separately, are called.

Having such a receptive system permits the engineer to forget about the need to get references to the gadgets, working with the construction for all backend, with a solitary language.

User Interface Components

UI Components are crucial when developing cross-platform mobile applications. Therefore, both frameworks must provide smooth and easy API access to native modules. In this regard, React Native has fewer components than Flutter.

On the one hand, React Native is very dependent on third-party libraries to obtain native modules. On the other hand, Flutter has UI widgets integrated; thus, the developer does not have to search for third-party libraries.

Programming Language

React Native uses JavaScript and Flutter uses Dart programming language. JavaScript is a dynamically typed language that has been extremely popular for years and it is often used with React, as well as with other JavaScript frameworks. Since many developers are usually familiar with JavaScript, adopting React Native is pretty straightforward.

Contrarily, with Flutter, developers necessarily have to learn Dart, which is not a very used language. However, it is not a puzzle either, considering that its syntax shares many similarities with Java and JavaScript.


Vacillate has a hot reload, implying that the designer can straightforwardly infuse new code into a running application, which can save enormous measures of time and speed the improvement interaction. Furthermore, to abstain from losing anything during reload, hot reload likewise keeps up with the application's state.

Respond Native was incredibly mindful of the achievement of this component among engineers and its 0.61 rendition was dispatched with a "quick invigorate" highlight that relates to the "hot reload". "Quick invigorate" further permits the designer to see changes made in the application without having to recompile it.

One more incredible benefit of utilizing React Native is that it has a major local area of designers who have contributed with numerous libraries. Those libraries can be used to assemble blocks and therefore accelerate the improvement cycle.

Documentation and Community

Ripple has an exceptionally exhaustive and broad documentation, giving engineers itemized guides and instructional exercises. Besides, Flutter also incorporates the Flutter assessor and debugger to help designers all through the application advancement.

Respond Native's documentation is additionally exceptionally rich and gives numerous instructional exercises, libraries, UI structures, articles and different materials. Further, it benefits from having an enormous local area and being essential for the React family.

On the inverse , Flutter doesn't (yet) have such an enormous local area of designers, taking into account that it is as yet a genuinely youthful structure. In any case , it has accomplished an extremely conscious size, depending on a ton of help from individual engineers, and it is progressively turning out to be more famous.

CI/CD Support

On the one hand, React Native demands a third-party solution to automate delivery and deployment, which means it does not provide developers with a CI/CD solution for Google Play Delivery or App Store.

On the other hand, Flutter allows the developer to use the command-line interface (CLI) to build and deploy Android and iOS apps. Nonetheless, it may also require third-party solutions if advanced automatizations are needed.

About the project: Dwipper

As part of my learning experience, I worked with both frameworks to develop an application called Dwipper, where users post their shower-thoughts as Dwipps.

The app had the following screens:

  • Basic login, registration and forgot password
  • All Dwipps, to see everyone's Dwipps
  • My Dwipps, where you can see all Dwipps you posted
  • New Dwipp, to write and post a Dwipp
  • Change password, where the user can change their password
  • Logout, where the user can logout

To me, this was a great learning experience. Flutter felt more intuitive, like how you work with widgets felt simpler than components in React Native. The only real issue we initially had was communicating with the app's backend. It wasn't something directly related to the framework itself, only a matter of figuring out what and how to send.

React Native, on the other hand, was slightly more troublesome, perhaps because I had no prior experience with JavaScript. The most frustrating part was working out how to set up the navigation between the login part and the "real" part of the app. Having to install a new component each time we needed something for a specific task wasn't very pleasant.

Comparing with other frameworks

Flutter vs Ionic

As Ionic was initially released all the way back in 2013, it lags behind Flutter slightly. If the developer isn’t sound in JavaScript, CSS and HTML5, the ramp up time for proficiency will cost time and money in learning the framework, while Flutter has a smoother learning experience. Being able to hot reload for quick experimentation allows for faster development as well.

React Native vs Ionic

At the point when we talk about React local versus Ionic, we can say that Ionic has extraordinary documentation and its devices are surely known by web engineers. However, since it's based on top of a program, the code can only with significant effort access local elements.

Respond Native, then again, has a major local area backing it up, which prompts more issues or issues being settled by different engineers on the web. Respond Native is converted into local code, having the option to arrive at 60 casings each second effectively, as though it's a local application. In any case, it is supported by a major organization, implying that any new apparatuses might be delivered by said organization's necessities.

React Native vs Flutter: which one is better?

Toward the day's end, when asking yourself which one is awesome, Flutter or React Native, everything boils down to individual inclination.

Somebody with more information and involvement with JavaScript or React will undoubtedly really like to utilize React Native, since the change is fairly smooth. Then again, a designer who partakes in the Object-Oriented worldview will undoubtedly really like to utilize Flutter.

In the event that you really want to foster a versatile application more complicated than Dwipper, you should seriously mull over utilizing Flutter since it's somewhat more well known than React Native at this moment. That fame may be useful when bug-hunting your application. More individuals implies a more extensive assortment of issues, which expands the likelihood of observing somebody with a similar issue as you or having it settled by another local area part who previously experienced it.
