Flutter vs React Native: A Comprehensive Comparison


Mobile app development has come a long way since the days of having to develop a separate version for iOS and Android. The emergence of cross-platform frameworks has revolutionized the mobile app development process. The two most popular frameworks in the market today are Flutter and React Native. They simplify the process by allowing developers to create a single codebase used across multiple platforms, eliminating the need to write separate code for iOS and Android. As a Mobile app development company, it’s always Flutter vs React Native.

Flutter, created by Google, uses a reactive programming model and Dart language, while React Native, created by Facebook, uses a declarative programming model and has a large community for support. Both frameworks have their unique advantages and disadvantages but have revolutionized the mobile app development process by making it more efficient and cost-effective.

What is Flutter?

Flutter is an open-source mobile application development framework, developed by Google. It was first released in 2017 and has quickly gained popularity among developers due to its unique features and ease of use. Flutter allows developers to build beautiful and high-performance apps for both iOS and Android platforms using a single codebase.

One of the standout features of Flutter is its use of a reactive programming model, which makes it easier to create dynamic user interfaces. Flutter uses Dart, a fast and object-oriented programming language that is easy to learn and write. Dart is also compiled ahead of time, which means that the code is converted to native code and executed directly on the device, resulting in faster app performance.

What is React Native?

React Native is another popular open-source mobile application development framework, created by Facebook. It was first released in 2015 and widely adopted by developers due to its ease of use and compatibility with both iOS and Android platforms. React Native allows developers to build high-quality and performant apps using a single codebase written in JavaScript.

React Native uses a declarative programming model, which makes it easy to create complex user interfaces. It also has a large and active community that provides developers with a wide range of third-party libraries and tools, making it easy to add new features and functionalities to your app.

Advantages of Flutter

Reduced code development duration:

In Flutter, a usual mid-size Android application takes limited time to developed and transported to the test device.

High productivity:

Flutter is cross-platform, it enables the same code base for your iOS and Android app. Ultimately, it saves both your resources and time. Flutter enables fast app startup times and less performance issues.

Fast and simple development:

Flutter consists of imperative and glorified features that lets you to instantly recognize the variations made in the code on hardware, emulators and simulators.


Flutter and dart programming both are open-source, and provide extensive documentation and community support to help out issues that may encounter.

Advantages of React Native

Optimal performance:

React Native is a real asset and improves the performances through native control and modules. React native enables us to make use of a different thread from Native API and UI.

Reusable codes and pre-developed components:

Code reusability is the biggest benefit that is from React Native. The developers are able to develop separate mobile app for each platform.

Hot reload

React Native is well known for its support for hot reload and also enables compiling and reading files where the developer had made the changes and offers a new file to automatically read the app from beginning.

Cost effective solution:

Developers don’t need to separate codes for both the platforms as both OS can be with a single programming language. This minimizes the time, effort, and development costs.

Flutter vs React Native:


Both Flutter and React Native offer fast and smooth app experiences.

Flutter has a slight edge due to its use of Dart, which is compiled to native code ahead of time.

React Native uses JavaScript and requires a bridge to communicate with the native platform, which can affect performance.

Development Time

Both frameworks offer significant reductions in development time compared to traditional native app development.

Flutter offers a faster development experience due to its hot reload feature, which allows developers to see changes in real-time without restarting the app.

React Native also offers fast development, but it may require more time to set up and configure.

User Interface

Both frameworks offer powerful tools and capabilities for creating dynamic and visually stunning user interfaces.

Flutter’s reactive programming model makes it easy to create complex animations and custom designs.

React Native’s declarative programming model and pre-built components make it easy to create complex user interfaces.

Community Support

Both frameworks have large and active communities that offer support, resources, and tools for developers.

React Native has a longer history and a larger developer community, which translates to more third-party libraries and tools.

Flutter has a rapidly growing community and strong support from Google, which suggests a bright future.

Limitations of Flutter:

Third party widgets and libraries support:

While Flutter is an open-source framework with its own set of widgets, it can lack third-party libraries. This can be an issue for developers looking for more specific functionality.

Huge file size:

This is partially true as Flutter apps can have larger file sizes compared to some other frameworks due to the fact that it includes its own rendering engine. However, the framework offers tools to help developers optimize their app size.


Flutter uses a Dart programming language. However, it has both benefits and drawbacks. This object-oriented programming language is not as great as other languages like C#, Java, Objective C, and JavaScript.

Limitations of React Native:

Lifecycle issues:

React Native’s lifecycle methods are well documented and understood, but there can be unpredictable impacts on app function due to the asynchronous nature of JavaScript.

Complex UI:

React Native can be used to create complex UIs, including screen transitions, animations, and interactions. However, it may require more work compared to other frameworks due to the need for custom styling and layout.

Longer initialization time:

React Native can have longer initialization times compared to native apps, but this is not a significant issue on modern devices.

Memory management:

React Native can have memory management issues when dealing with large amounts of data, but it is not inherently unsuitable for computation-intensive apps. Careful coding practices and optimization can help mitigate performance issues.


Flutter vs React Native: Flutter and React Native have revolutionized the mobile app development process, allowing developers to create cross-platform apps more efficiently and at a lower cost. Their unique features and ease of use have made them increasingly popular among businesses and developers alike. With Flutter’s use of a reactive programming model, and React Native’s declarative programming model and large community support, both frameworks have their unique advantages and disadvantages. However, they both provide a significant improvement over the traditional mobile app development process and are set to reshape the future of mobile app development. Both frameworks are constantly evolving, with new features and updates being released regularly. It’s important for developers to stay up-to-date with the latest advancements in both Flutter and React Native to determine which framework is the best fit for their project. Ultimately, the decision between Flutter and React Native will depend on the requirements of the project and the preferences of the development team.
