Flutter and React Native are the two most common cross-platform mobile application development frameworks available at the moment.

These juggernauts are sponsored by two of the world’s biggest technology companies: Google founded Flutter and Facebook founded React Native.

We’ll compare Flutter vs React Native in this blog, examine what makes each system unique, and discover why they’re so highly sought-after.

What is Flutter? – An Overview

Google built Flutter, a cross-platform user interface system. It debuted in May 2017 and has steadily increased in popularity since then.

Flutter’s primary selling point is its ability to support cross-platform frameworks using a single code.

Historically, if a business desired to develop a usable application on the web, mobile, and desktop, it would have needed to employ several tools.

For instance, it may require hiring a web developer, another developer with experience developing desktop applications, and a mobile application developer to create apps for iOS and Android.

Check out Some Noteworthy Stats about Flutter:

  • 68.8% of the developing world adores Flutter.
  • Globally, 39% of the population uses Flutter to develop cross-platform mobile applications.
  • 7.2% of the community opts for Flutter because of the popularity of its tools & libraries.
  • There are already over 150,000 Flutter apps out there on the Play Store alone
  • Google says 500,000 developers use Flutter monthly

What is React Native?

React Native is a common open-source platform built on the JavaScript programming language.

It is mainly focused on native device loading and is primarily compatible with Android & iOS.

React Native is composed of XML-Esque markup and JavaScript, also known as JSX.

It is funded by Facebook, with over 50 dedicated engineers currently working on the framework.

Some Noteworthy Stats to Consider for React Native:

  • In 2020, 42% of developers were reported to use RN for cross-platform application development. (Source: Statista)
  • 11.5% of developers prefer to use React Native for its native tools and libraries.
  • 58.5% of the developing community loves using React Native.

Key Differences Between Flutter and React Native

differences between flutter and react native

There is a lot in common between Flutter vs. React Native in 201, albeit with some substantial significant differences.

To begin, Flutter’s codebase is written in the Dart programming language, while React Native’s is written in JSX, which stands for JavaScript XML.

When it comes to Flutter vs React Native, remember that both languages are syntax-based in the C style and adhere to object-oriented principles. This shared ground means that Flutter and React Native are essentially similar in terms of design and code.

  • Dynamic vs. Static Programming

The meat of the programming lies in the primary programming language is significantly different.
JavaScript is complex because it’s not compiled. This capability makes it very flexible. Dart is intricate and easily translated, which means it has the best of both worlds.

Statically typed languages are safer because they allow you to use the correct data form of a variable or result explicitly. For example, you can implement a string with a number, which results in an error.

Static would mean less error prone. You can ensure more data security and allow error checking by going with the TypeScript subset of JavaScript.

  • Layout

Flutter builds the user interface using widgets, while React Native uses JavaScript and JSX.

Since Flutter widgets are pre-built, you are not required to make your custom widgets unless you wish to.

You don’t have to think about incompatibility problems with these extensions because they were developed and checked by Google.

One thing to note is that when developing mobile apps with a computer language such as Swift, you usually cannot see the code used by Apple to build user interface components such as buttons.

By comparison, with Flutter, the code is viewable, allowing you to see how Google made all the widgets.

Flutter vs React Native might come up as a sharp comparison but they have something in common regarding layout construction: both use CSS Flexbox.

Although their implementations vary, as long as you are familiar with Flexbox, you should have no trouble creating the interface for your app.

The team that developed Flutter also created the developer tools for the Browser, simplifying the transition since the debugging tools are very similar.

  • Development Tools and Documentation

The documentation for React Native is excellent. Regrettably, it is more geared toward experienced web developers who are already acquainted with JavaScript and contains some holes. For example, critical features such as navigation are not well known.

Additionally, locating knowledge about how to create native libraries can be challenging.

In comparison Flutter vs React Native, Flutter comes with extensive documentation.

It includes comprehensive guides that are supported by graphics and video tutorials.

The cool thing about Flutter is that it contains many resources for app creation, including a debugger and a Flutter inspector.

  • User Interface

React Native renders native components for each platform using the JavaScript bridge.

This function enables the development of native Android and iOS apps with the look and feel of native applications.

You know what is react native as the businesses can leverage a large number of pre-built components that can be used as building blocks.

Regrettably, there are disadvantages as well. For example, it’s challenging to reproduce complex user interfaces in a React Native application.

Additionally, React Native components behave differently across platforms.

Flutter includes UI widgets, which simplify the process of developing native-like applications.

There is no need to look for third-party libraries; a comprehensive collection of framework widgets suffices.

Additionally, Flutter application development ensures cross-platform apps that run smoothly regardless of the platform.

  • Developers’ Productivity

React Native enables a high degree of code reuse across platforms.

Additionally, the developer community has built many libraries that can be used as building blocks to expedite growth.

Additionally, React Native has a hot reload technology that lets you display changes to your app without recompiling it.

And when it comes to Flutter vs React Native, it is Flutter that includes a hot reload feature, which enables rapid iteration and immediate feedback.

Additionally, Flutter enables fast application compilation.

  • Community Support

A broad community of contributors is critical to success in open-source development. The fact that Reacts Native provides these facilities is remarkable.

The framework was first released in 2015 and quickly gained popularity among Facebook developers. You can find information on the various React Native social media outlets here.

Flutter is smaller than React Native but is developing much more quickly. Flutter was launched in 2017 and is on the rise.

It is becoming increasingly popular too.

Flutter vs. React Native: Performance

Flutter and React are both open-source projects, which means they are entirely free to use.

Both repositories are well-maintained, which makes sense given their origins at Google and Facebook.

It is necessary to assess apps made with both frameworks in two ways: virtually using a built-in iOS or Android emulator on your device or natively on your phone.

If you want to build for iOS, you’ll need an Apple computer, as the SDK is only available on Apple computers.

Users of Windows and Linux are out of reach.

Fortunately, Android development apps can be developed on any platform.

Both frameworks support hot reloading, which enables you to adjust and immediately see them.

This improves production efficiency by eliminating the need to pause and restart your apps to view updates constantly.

There is some controversy about the true native nature of Flutter vs React Native.

To be considered genuinely native, they must be written in the language for which they were created — Swift for iOS and Kotlin/Java for Android.

The experience of using a React Native and Flutter application is, for the most part, Native. Flutter’s Dart code is compiled to C, which is about as similar to Native as you can get.

You may reasonably conclude that will result in improved results.

Reflectly’s creators recently upgraded the software from React Native to Flutter and noticed a significant performance boost.

This is an illustration of an improvement.

However, this will not be the case with every application; there are several edge cases to consider, including the application’s form, codebase, database, phone, and operating system.
