Flutter vs. React Native – What to Choose for your App in 2021?

Do you need to develop mobile apps quickly? And reduce costs with cross-platform development, but are not sure which technology to choose?

Choosing the correct framework for your mobile application development determines its efficiency and its set of features. If an app is poorly designed, it will overheat its device, increase wait-time and fail.

This is where the long-standing battle between native and cross-platform development originates from. Therefore conflict between the two conventional cross-platform development frameworks in precise: Flutter vs. React Native.

In this blog, we’ll compare the top market players – Flutter and React Native – from the app owners’ viewpoint to help you find which framework most closely fits your app plan.

Developed by Facebook, React Native is open-source released on GitHub that supports both iOS and Android platform’s native APIs. On the other hand, Google’s Flutter is a great move, which lets you build Android and iOS highly responsive native apps simultaneously.

In this competitive world, the eventual goal of any Mobile App Development Company is to select a cross-platform framework that should allow developers to write a single codebase and deploy it through multiple platforms. In that way, we can offer help to our customers in selecting the precise framework that might best support them to attain their goals.

Build by Google, Flutter is a Software Development Kit (SDK) that allows developers to create high-performance, high-reliability and very fast applications that can run on multiple platforms like Android and iOS. Flutter is powerful because of it has thin layer of C/C++ code but most of its systems are implemented in Dart which helps developers to easily approach read, replace, or remove. This gives developers great control over the system.

General Note: Dart is a programming language initially developed by Google.

Flutter or React Native?

React Native has shown plenty of recognition in recent years, typically from the ReactJS and web platform. React Native is written in JavaScript, which has fired up its acceptance rate for many companies switching over it. At the same time, Flutter has been endorsed profoundly by Google since 2017 and has generated significant interest by the developers. Flutter is new in the competition of the mobile app development industry and has a long potential to go ahead in the competition.

Below is the quick comparison between Flutter vs React Native.

The Language Stack

Flutter is an open-source mobile application framework that fully works on a different programming language called Dart. While on React Native, you can build mobile apps only using JavaScript.

Architecture

Dart is based on C/C++, Java and supports things like abstraction, encapsulation, inheritance, and polymorphism.

React Native’s application architecture is known as Flux. Facebook uses Flux to build client-side web applications. It mostly follows the MVC framework.

Performance

React Native

For React Native, you need a bridge to call Swift or Android or Windows & Mac APIs, whereas with Flutter, it’s dart, so you don’t need that the whole thing as it would be native; this also solves the problem with the JS ecosystem split between many different versions like CommonJS, AMD.

Flutter

Flutter has the benefit of Dart, and there is no JavaScript bond for initiating interactions with the device native components; the speed of development and running time accelerate significantly.

User Interface (UI/UX)

React Native

App developed on React Native need to use third-party libraries like React Native does not have its own UI components library. We need an open-source UI component named NativeBase created by geekyants. NativeBase offers you the basic set of UI components, and currently, there are three main UI libraries:

  • Shoutem UI Components
  • React Native Elements
  • Native Base components

React Native’s User Interface is similar to using HTML without any CSS framework. It is built more on the native components both for Android and iOS also better User Experience (UX) when a user taps into the Operating System.

Flutter

Flutter uses built-in beautiful Material Design and Cupertino like iOS-flavor widgets, rich motion APIs, smooth natural scrolling, and platform awareness. Flutter has its own UI components, material design, adaptable widget sets and an engine to reduce them on Android as well as an iOS platform. Here are a few examples of Flutter Widgets:

  • Drawer
  • Inkwell
  • GestureDetector
  • DefaultTabController

Constancy for Development: React Native vs Flutter

Constancy becomes a key factor when you are developing a cross-platform app. As Flutter is much new in the cross-platform industry, the number of businesses that have implemented the SDK for developing their cross-platform apps are very less. But, with the Flutter version 2 just released, which delivers enhanced developer tools and asset systems. Alternatively, React Native showcase page of apps that have been developed using the framework is much higher. It was quite stable from earlier and it also loves the support of a large community of contributors.
