React Native Vs. Flutter: At a Glance

This comparison is based on the research online and interviews with the experts (interviewed experienced React Native and Flutter developers in-house). You will find complete overviews and comparisons —Flutter V/S React Native. Let’s explore;

What is React Native —An Overview

If I have to say in a simple sentence, React Native allows developers to build cross-platform applications with Native performance. Facebook created this app development platform in 2015, and it will enable developers to use the technology in the existing Android and iOS applications or build a cross-platform application from scratch.

Source: React

React Native combines Native development with React’s JavaScript Library along with easy-to-use tools to build an interactive user interface. It’s an open-source platform with several built-in core components to help develop functional applications for both iOS and Android platforms.

Top Features of React Native

React Native is the first choice for developing a hybrid application. It is so because there are plenty of features to help developers create great applications with rich components. Let’s explore the top features of React Native;

Declarative Components: Declarative components enable developers to create interactive UIs by offering declarative views. That means with declarative views, code becomes more predictable, making it easier to debug.

Component-Based: Creating complex UIs becomes easier —thanks to their encapsulated components that help manage their state. Then compose them to make complex UIs.

Developer Velocity: When it comes to making any changes in a new and existing app, developers are empowered to see local changes in seconds.

Live Reloading: Any changes to JavaScript code can be live reloaded, and the changes are visible within seconds without rebuilding the native app.

Portability: React Native slogan “Write Once, Use Everywhere” became widely popular. That means developers can reuse code written for a particular platform across iOS to Android and vice versa.

React: A framework enabling developers to create web and mobile apps on top of JavaScript.

Native: This is the best feature of the framework that enables developers to write code using JavaScript and render it using native components.

Cross Platforms: Using React Native, startups can get cost-effective solutions for both platforms —IOS and Android.

Top Use Cases of React Native 

React Native is used for building hybrid applications and is widely known for the following use cases;

  • Building simple yet effective cross-platform application
  • Creating prototype applications faster and quicker
  • Designing complex apps with simplified UI
  • Requiring nearly native apps on the top of hybrid technologies
  • App requiring responsive UI/UX using FlexBox

What is Flutter —An Overview

Built and released in 2017, Flutter is the most popular open-source software development kit for building interactive UI for smartphones. The SDK is used to create high-performing cross-platform mobile applications while using the Dart programming language developed by Google, making it the perfect mobile app development platform. Apps built using Flutter can be deployed across all devices from a single codebase.

Top Features of Flutter

Flutter became the talk of the town in the tech arena soon after its release in 2017, not because Google maintained it but because of the features and functionalities. Let’s take a look at the features from Flutter;

Hot Reload: This feature is also provided by React Native, though Flutter has made it exceptional. It allows developers to see the changes instantly in the app. Hence it becomes a handy feature for developers to write code while visualizing the impact right in the app.

Cross-Platform Development: Like React Native, Flutter is also an open-source, cross-platform SDK. That means it allows to write code once, maintain it and use it for iPhone, iPad, and Android applications.

Easy to Use Native Features: Whether it is through native codes, third-party integrations, and platform APIs, the Flutter app development process is extremely easy with these features. That means the developers can easily access native features and SDKs and utilize them while building android and iOS applications. Even the Swift and Kotlin programming languages can be used.

Minimal Code: Less code means less loading time. Flutter applications are built using Dart programming language along with JIT and AOT compilation, enabling faster starting time and accelerated performance.

Widgets: Flutter makes building customizable and complex widgets easy while encapsulating all widgets from Material Design and Cupertino pack, making the SDK a glitch-free experience.

Top Use Cases of Flutter

Flutter is best known for building UI for Android and iOS mobile apps. It was released in 2017, though its use case made the platform widely famous in the tech arena. First, take a look at its use cases.

React Native Vs. Flutter: Comparison

React Native and Flutter platforms are almost identical in performance, features, and functionalities, making them classic rivals. That’s why it may be hard for clients or a new-age startup, or a fresher developer to distinguish between the two and decide which platform will be the right choice. So, we have made this easier for you by comparing the top points.

AspectsFlutterReact Native
PerformanceHave an edge over React NativeA little sluggish performance as compared to Flutter
ArchitectureBased on Skia and Layered architecture with reactive user interfacesBased on Flux, heavily relies on JS runtime environment
Learning CurveMediumStiff


When it comes to performance, both are doing great in their respective niche. As you have seen, top business leaders use both Flutter and React Native platforms. However, based on the app development requirement, both differ a bit in terms of performance;

React Native: React Native uses JavaScript programming language to communicate between modules, and the app grows higher as the number of frames drops in the ‘hello world.’

Flutter: Flutter has the edge over React Native in this case. The reason is Flutter requires no bridge to communicate between modules. Besides, the native components are available by default.


Platform architectures become essential when you have to adapt to the changing tastes of technologies to do away with the complex system. It ensures the app functions well, even if it has many parts. Here is what architecture both Flutter and Reactive Native has;

React Native: React Native follows an exemplary architecture, though there’s always a bridge between native and JavaScript threads. As the function suggests, JavaScript code communicates with the platform and Native API. Unfortunately, in some cases, it increases the app size, resulting in sluggish performance.

Flutter: Based on layered architecture, cross-platform app development is flawless, offering segregated hierarchy to platform-specific widgets —from top-level widgets to basic level widgets.  

Learning Curve

The learning curve is not always about developers, whether it is easy for developers to understand how to utilize the technologies or the platform. It can also be for projects, as platforms with easy learning curves offer simplified features and take a shorter time to build applications, saving a significant amount on app development costs. Let’s explore what these two technologies have in to offer;
