Flutter Vs React Native which is better?

Are you deciding between Flutter vs React Native? Learn how these two vary and what advantages and disadvantages each has.

The rise of mobile applications has a significant impact on the development industry. With more than 3.6 billion mobile users globally, new approaches that take less time and effort are needed for the development of mobile apps. Flutter and React Native are the two prominent hybrid frameworks for developing apps in 2021. And they both continue to gain in popularity.

Because they are two of the most popular multi-platform mobile app frameworks, Flutter and React Native are natural rivals. Disputes rage… developers quarrel… In the end, either one or the other is used to ship apps.

Which is better, then?

The wise response is, “It depends,” which senior engineers will respond with a mischievous grin. Both offer advantages and disadvantages, so the choice ultimately comes down to compromises.

That’s hardly a very satisfactory response, though. It’s comparable to saying that the best NBA player “depends on their function.” That doesn’t generate engagement, attract clicks, or pump up talk shows!

What is Flutter?

Google created the cross-platform UI framework known as Flutter. Flutter’s popularity has risen gradually since its initial introduction in May 2017.

Using a single codebase to build cross-platform apps is one of Flutter’s primary selling advantages. In the past, a business would require several tools and developers to produce an application that was accessible on the web, mobile devices, and desktop computers.

For instance, you could require:

  • A web developer that specialises in that field created the website using React.
  • The desktop version was made by another programmer utilising C# and Java.
  • a committed mobile developer that creates Android and iOS apps using Kotlin and Swift

What is React Native?

Facebook developed the cross-platform React Native framework. React Native lowers the entry-level for JavaScript developers by making it comparatively easy to construct cross-platform applications using a codebase written in JavaScript.

Web development has been around for a while, and the majority of web developers have spent the majority of their careers using JavaScript. Although mobile development is still in its infancy, the ecosystem as a whole has grown considerably in recent years.

The learning curve for developing mobile apps with React Native won’t be as severe if you already know JavaScript.

React Native is a popular tool for app development these days. One notable application that was created with React Native lately by Microsoft is the new Xbox shop app.

Which is Better Flutter Vs React Native ?

Computer Programming Language

the Flutter Framework and Dart

In 2011, Google created Dart as the programming language for this framework. Many claim that Dart programming runs a tiny bit more quickly than React Native. It’s difficult to criticise Dart’s beautiful syntax. However, learning its object-oriented ideas might be challenging.

How Dart code is shown
As a result, there are fewer developers who have acquired it. Dart falls behind when compared to React Native and Flutter in terms of programming language usability.

The React Native Framework and JavaScript

One of the most popular languages in the world, from website designers to software professionals, JavaScript is simple to create with. JavaScript has a large developer community, hence tutorials are available.

It’s simple to understand how this framework may help you save time and money when you consider the pre-built modules it provides. Because of this, when our developers are asked if Flutter will replace React Native, they typically respond in the negative.

Flutter vs. React Native  Device compatibility

Both Flutter and React Native support ARM-powered Android smartphones as well as iPhone 4s and later Apple devices. For the development of applications, both also enable Android and iOS simulators.

Flutter apps need iOS 9 or later on Apple devices, and React Native apps need iOS 11 or later. For Flutter apps on Android smartphones, the API level must be 19 (Android 4.4) or above, and for React Native apps, the API level must be 23 (Android 6.0).

Android 5 or iOS 10 and higher are the bare minimum supported versions for Expo-based React Native apps.

Flutter vs. React Native which is more in Demand

Due in part to React Native’s affiliation with the well-known web framework React, React Native is now slightly more well-known than Flutter. Additionally, because React Native has been around longer, it has a bigger user base.

As a result, React Native developers are now in more demand than Flutter developers. Flutter isn’t disliked despite this; in fact, it’s been more well-liked over time.

The Flutter plugin for Android Studio comes with code tools, making it much simpler to develop and debug your code. The fact that this plugin has around 12 million downloads as of this writing demonstrates how well-liked Flutter is.

Flutter vs. React Native  Architecture

Flutter’s Skia

The framework makes use of a platform-specific shell, the Dart language VM, and the Skia 2D graphics rendering package. Dart’s source code is first compiled to produce native code. This idea is essential. Its code is a simple and quick fix that works with iOS or Android without any issues.

To make things work, no cumbersome programming bridges are required. If React Native and Flutter were to be judged just on the elegance of their designs, React Native would come out on top.

Flux in React Native

This framework utilises Facebook’s Flux design, however it needs a JavaScript bridge to be integrated. This annoying reality is a fundamental distinction between Flutter and React Native that causes app design to move a little more slowly than Dart.

Developers knowledge, and Code Exchange

While recruiting has the greatest, most significant influence on the choice to employ Flutter or React Native, I should also point out that sharing code, expertise, and developers is a crucial consideration.

What is superior than excellent code? reduced code. And sharing code between several apps is one of the finest methods to have less code. Your initial development time may be shortened, and long-term upkeep may be made simpler.

There’s a good chance that your business uses JavaScript or React.js in some capacity for its servers, web apps, and other applications. React Native has a significant advantage over Flutter in the area of code sharing across React.js apps, Node servers, and other platforms.

Flutter Vs React Native Performance

Flutter, as we’ve already established, is developed in the Dart programming language, which enables faster code compilation than JavaScript. Additionally, because of this, Flutter automatically shows animations at 60 frames per second. Every Flutter app typically has a high performance level as a default. However, it is important to take into account a few typical issues that might impact the rate. Flutter offers consumers suggestions that assist in achieving the desired outcomes. These suggestions consist of:

  • Performance improvement using delayed loading and tree shaking
  • Precaching, picture placeholders, and suppressed navigation transitions increase performance.
  • making functional Flutter widgets
  • Flutter also suggests limiting build

React is written in JavaScript and Native, as we have already explained. For applications, merely demonstrating a high degree of performance is insufficient. To get the desired result, developers must thus blend additional interactions with native ones. Given both JavaScript and native components make up React Native’s design, the framework needs a JS bridge to communicate with native components. React Native is a tiny bit slower than other tools because of this as well.

Flutter Vs React Native Unified User Experience

Skia is used by Flutter to render its UI, which unifies the appearance and feel across all platforms. They may now create bespoke user interfaces and maximise performance without being limited by the platform’s primitives.

On the other hand, React Native makes use of the DOM on the web, the Android layout system on Android, and UIKit on iOS. This implies that even while you can create apps that seem extremely identical, they will differ in taste depending on the platform.

Flutter has been criticism for having to recreate a variety of issues that the platforms have already mostly resolved, including accessibility, font resizing, and other issues.

Flutter Vs React Native Static vs dynamic programming

There are substantial differences between Flutter and React Native’s basic programming languages.

JavaScript is by definition dynamic. This makes it incredibly flexible since you can alter the values of different data kinds. Dart offers the best of both worlds since it is both dynamic and static.

Since you are required to declare and use the right data type, a statically typed language is typically seen as being considerably safer. For instance, assigning a number to a string results in an error.

If you choose to utilise TypeScript instead of JavaScript, a rigorous syntactical superset of JavaScript, you may impose better type safety and error checking.

Installation Flutter Vs React Native

Flutter installation takes longer
You must get the binaries for the particular platform you select from GitHub in order to install this framework. There is even one more step involved in installation for macOS: downloading and adding a PATH variable for an file. This is one of the main distinctions between Flutter and React Native, which makes installation slower and more difficult.

NPM and React Native

This framework is simple to use during installation. If you know JavaScript well, installing via the node package manager is simple.

It’s crucial to remember that neither of these frameworks has a native OS package management or a one-line installation method. Therefore, neither approach is suitable in this case.So in the comparison between React Native vs Flutter, we’ll choose to React every time.

Flutter Vs React Native Third Party Libraries

Many libraries and tools that were created for JavaScript or React are used in a typical React Native project. A few of these include mobx, redux, ramda, eslint, babel, jest, prettier, react-devtools, typescript, npm, and yarn.

Developers working with Node.js and the web frequently utilise all of these libraries. It follows that the merged communities may contribute to and enhance these tools, as well as (again) exchange information and aid one another.

On the other hand, Flutter often uses libraries designed specifically for Flutter. Although there are a few independent Dart libraries available, the community is far smaller than JavaScript.

Having said that, it’s important to note that Dart is a type-safe and null-safe language and that it has an uniform formatter, testing, compiler, analyzer/linter, and package management. This implies that you would probably need fewer third-party libraries when using Flutter and Dart.

Time to Develop


Which is faster in terms of development pace, Flutter or React Native? This structure fails. Developers do not utilise or understand Dart as frequently. Despite the fact that the majority of users adore the hot reload functionality, this framework is not supported by many text editors and IDEs, which prolongs the development process.

React Native

The only thing that separates Flutter from React Native is JavaScript. JavaScript undoubtedly makes development simple and available to more web designers and developers.

Flutter Vs React Native Project size

Flutter may require a minimum of 2 GB and a maximum of 4 GB of disc space for a project (500 MB for the IDE and 1.5 GB for the Android SDK and emulator system image). The default app in the new Flutter project can occupy up to 60 MB of space on Android Go devices. Because there are more essential files, etc., this is typical for flutter.

React Native is a suggested framework for developing mobile apps since it can reduce the size of an app from 26.1 MB to 3.1 MB in comparison, while being highly challenging to debug, etc.

React Native’s advantages and disadvantages

React Native’s benefits

  • due to the use of the incredibly popular JavaScript language, extensive base packages
  • One codebase allows developers to create an app for various devices at once rather than separately.
  • Developer autonomy encourages code reuse and reduces costs
  • Generally mature
  • a large, vibrant community

Simple for React Native developers Drawbacks:

  • Native developers are still required
  • Compared to Flutter Debugging difficulties, poor performance
  • fewer out-of-the-box components
  • many unused libraries and packages
  • Larger than native apps, fragile UI apps

Flutter’s advantages and disadvantages

Flutter benefits

  • Utilizing the same codebase quickly
  • The experimenting and bug-fixing process is made easier by “Hot Reload.”
  • Layered architecture enhances control and customization options
  • Excellent documentation
  • Separate UI prevents mistakes
  • Easily navigable designs

Flutter Drawbacks

  • Young framework with several widespread problems that are difficult to fix
  • Apps take up a lot of space and are slower to download.
  • Dart, a programming language, and its infrastructure, are updated often.
  • Although amazing, libraries and assistance are not as effective as native development.

Comparison between Flutter vs React Native in brief

Now that we’ve seen it, Flutter and React Native have a lot of similarities. They are both open-source frameworks that are available to everyone first and foremost. Both of them were created by reputable businesses: Flutter was produced by Google, whilst React Native was made by Facebook. You may examine this information using NIX to compare the fundamentals of Flutter with React Native.

Because it is more resistant to system upgrades, Flutter is simpler to use. It implies that the software will remain the same even if iOS or Android updates the OS. React Native, on the other hand, is dependent on native components, thus when an update is issued, certain issues may arise in the launch app.

The main distinction between Flutter and React Native is the presence of Google team-developed plugins for geolocation and mapping. Unfortunately, apps that only need a single location and do not require tracking operate better with React Native apps.

In conclusion, Flutter and React Native are excellent options for cutting costs and time during the development of mobile apps. The developer’s and the company’s choices will choose which framework to use.
