Flutter vs. React Native – A Growing Divergence of Opinion

It's not about how well Flutter defeats React Native or Vice Versa. Read to know how well a framework (Flutter vs React Native) handles a particular scenario in development

Flutter is a relatively simple framework that is used to design cross-platform mobile applications. Keeping the initial reservations aside, mobile app developers have started believing in what Google claims to give some credence and attempt to build Android applications. Every new development stack brings new dimensions along with it. Development efforts are defined by code clarity, quick iterations, and strong developmental concepts. While both Flutter and React Native give native look and feel, Flutter wins in case of App Performance than its closest counterpart. Since there is no JavaScript bridge for initiating interactions with the device native components; it helps expedite the speed and running time of development. Going further, owing to its industry adoption and experience, React Native manages app development lifecycle in a much better way than Flutter. Here are some conceptual highlights based on my learning experience with Flutter and React Native that will provide you with a basic understanding about the subject.

Flutter – A General Summary

Mobile users expect their apps to have beautiful designs, smooth animations, and great performance. To deliver on this the developers need to have features faster than ever without compromising on quality or performance. That’s why Flutter was built.

Flutter is Google’s mobile UI framework that provides a fast and expressive way for developers to build native apps on both iOS and Android. This is because apps and interfaces built on Flutter are based on a single codebase, compiled directly than native codes, use the GPU and access platform API’s and services. It is also a primary method of creating applications for Google Fuschia. Flutter is also a mobile app SDK for building high performing, high quality, accurate apps for iOS and Android from a single codebase.

Flutter Framework

Flutter framework is formed into a series of layers. Each layer is built upon the previous layer.

Flutter Framework

Check the API documentation for all sets of libraries.

Increases Productivity

  • Flutter allows the developers to be highly productive. It’s now easy to develop iOS and Android.
  • A lot many things can be done with less code. The code is not constrained to one operating system. It can be used interchangeably.

Allows Easy Iterations and Prototyping

  • Flutter allows the developers to experiment by changing code and reloading as the app runs (A unique hot reloading feature)
  • Flutter development accords for fixes to code and permits debugging from where the app left off

Customized Applications

  • Flutter allows congruity of parts with one another and with the whole, create highly customized, beautiful applications and user experiences
  • Flutter is stuffed with a rich set of Material design and Cupertino (iOS flavor) widgets that are created by making use of Flutter’s own framework.
  • Simple and beautiful brand driven designs can be constructed without the limitations of OEM widget sets.

Fast Development

  • Flutter is engineered for high development velocity
  • Flutter is also shipped with a rich set of customizable widgets or built from a modern react framework
  • Flutter integrates with popular development tool which means you can get started quickly with the editor or IDE

Expressive and Flexible UI

  • Flutter moves the widgets, rendering animations and gestures into the framework to give you complete control over every pixel on the screen. This means you have the flexibility to have custom designs. These widgets are both in Cupertino for Apple and in Material Design for Google.
  • Flutter apps follow platform conventions and interface details such as scrolling, navigation, icons, fonts and more. This is why apps built with Flutter are featured both on App Store and Google Play Store.
  • Flutter is good for developers both new and experienced. If you are new to mobile, Flutter gives you a fast, fun and modern way to build native apps. If you are an experienced mobile developer you can add Flutter to the existing workforce and tools to new expressive apps. Flutter is free and open-source. It is used by developers in organizations across the world including enterprises, startups, and agencies.

Written in Dart, Flutter is a relatively new platform used for developing Android and iOS apps from a single codebase (do more with less code, check Flutter framework above). In addition to writing a lot of plain DART code to model and animate charts, it is capable of handling fairly complex UI that includes animated charts by making use of CLI tools, pre-built widgets, and 2D rendering engine.

Flutter vs React Native: Google Trends Comparison:

flutter vs react native

React Native – A Basic Explanation

React Native is a JavaScript library utilized for building UI. It is maintained by a community of expert React Native developers and some of the leading corporations, including Facebook and Instagram. It helps mobile app developers to use the same code again in any Android or iOS apps.

React Native is the framework to build native apps. React Native is a library that is built upon React and JavaScript and allows building native mobile apps for iOS and Android that use React and JavaScript to build during development. React we build apps to tailor for Android and iOS but we do not have to write any Java or Swift code and we learn the technology once to build the Android application and to build iOS app. But what React Native isn’t is that it is not an app which provides you with a component library of pre-styled components that look like material to sign on Android or iOS. Instead of this, it gives you building blocks which can be styled on own.

Build React native apps

It is easy to build react native apps for both Android and IOS.  Presence of reusable components across Android and iOS makes coding easy. Compared with JS frameworks like Angular JS or Meteor JS, React Native is UI focused that makes it more like a JavaScript library than a framework. The asynchronous JavaScript interactions with the native environment make the resulting UI highly responsive. It offers third-party plugin compatibility, less memory usage, and a smoother experience.

Flutter vs React Native Distinction

S. no.



React Native

1User InterfaceNative ComponentProprietary Widget
2Native AppearanceNative experience is more because of the access to device core functionalitiesNative appearance is lower because of the dependency on third party API’s
3App PerformanceHigher because of fps animation standardLow because it used JavaScript bridge for initiating interaction
4Framework MaturityLower because it’s very new in the industryHigher because the framework is 3+ years old
6Industry AdoptionCurrently, it is low because it is not known to masses and is only a few months old.Higher because brands are using it for years.
7Configuration and SetupMore straightforwardLacks at streamlining setup and configuration
8ToolingIt has greater compatibility with the IntelliJ idea, Visual Studio Code, and Android StudioThere are a large number of IDE’s and tools support React Native
9Lifestyle ManagementThere are no tools that explicitly save action state. The user is provided with just widget inheritance that only allows for stateless and stateful conditions, without any tools for explicitly saving the application state.It is better at simplifying app lifecycle, management, and optimization
10Code StructureMessier styling because of no separation between templates, styles, and data in a Dart file.Code structure and styling is a lot direct with JavaScript
11DocumentationIt is straightforward and clear to follow through.Chaotic and unclear.
12Brand PresenceGoogle Adwords, Alibaba.com, Groupon etc.Walmart, Facebook, Linkedin, Instagram etc.

Harking Back

Getting started with React native and Flutter is easy. The code is free and open source. But the real challenge emerges when you need to select between the two. If you know JavaScript and are also familiar with some tools and constructs in React Native library like NodeJS, the CSS Flexbox system, ECMAScript 6, and JSX, a JavaScript syntax extension that’s similar to XML and that is used to display data, React Native appears to be a reliable option for development.
