Flutter vs React Native: Which Framework to settle on for Cross-Platform App Development?

Cross-platform mobile development is highly regarded owing to the numerous benefits it brings along as compared to native app development. In this blog post, we will compare the top three Cross-platform mobile development platforms Flutter Vs React Native to help you make a better decision when going for app development.

React Native vs. Flutter in Development

Both Flutter and React Native are popular frameworks for cross-platform mobile app development. But each of them has its peculiarities. We can differentiate both platforms on the basis of these points beow:

Programming language
Architecture
Installation and initial configuration
Development tools and documentation
User interface (UI)
Developers’ productivity
Community support
Cl/CD support

Programming Language
React Native uses JavaScript. In particular, ReactJS — a JavaScript library for building user interfaces. For web developers, working with React Native comes easy.

Another distinct advantage here is JavaScript’s solid popularity. According to Stack Overflow 2020 developers’ survey, JavaScript has been the most commonly used programming language for eight years in a row, so assembling or training a React Native development team will be easy.

With Flutter, you have to use Dart — a programming language created by Google. As a client-optimized language, Dart has many advantages. Take productive app development, for instance.

Luckily, Dart resembles other popular OOP languages, such as Java and C++. If you are familiar with either of those, you’ll pick it up quickly. On top of that, consistent with Stack Overflow, Dart is more loved by developers than JavaScript.

Flutter

A highly popular open-source framework for cross-platform mobile app development, the Flutter framework is highly popular among front-end developers.

The framework allows code re-usability from 50–90% besides providing amazing user interfaces. It utilizes Dart for high-quality application development.

PROS:
Complete Development Ecosystem: thanks to the supply of pre-built widgets, CLI tools, and APIs.
Easy Customization Options: Allows creating new widgets or customizing the existing ones.
Cost-efficient: Open source hence free.
Hot Reload: Allows quicker bug fixes, easily build UIs, and add features.

CONS:
Large app size:
This prompts developers to reduce the number of libraries and compress images to make necessary adjustments
An average Flutter app is 4.7 MB in size which is quite large compared to an Android native app starting typically from 1 MB.
Native API: As many native APIs are not provided, third party packages may be required.

React Native

Built by Facebook in 2015, React Native is another popular cross-platform mobile app development framework.

The framework makes efficient use of the popular high-level programming language JavaScript besides allowing developers to write few components using Swift, Objective-C or Java as & when required.

The use of native UI controllers ensures an amazing GUI and hence an app experience close to native apps with React Native. It even allows 90% of code re-usability overall.

PROS:
High-quality user interface: thanks to native UI implementation, apps appear as if native apps
Faster development time: Due to the availability of ready-to-use UI components
Native Functionality Access: Camera, accelerometer, etc., available
Cost-efficient: Open source hence free

CONS:
Not-so-seamless navigation
Complex animations and transitions hard to achieve
Comparatively slower running apps

Now let’s come to the conclusion then, which of those three frameworks is best for cross-platform mobile app development?

The winner is… Flutter. Irrespective of the few cons Flutter has, it is indeed quite a robust framework that allows building beautiful native apps ensuring a high-end performance.
