React native vs Flutter, let the battle end today!
We will start by understanding,

What Is Flutter?

Flutter is an open-source framework that can be used to build beautiful, high-performance, and native-feeling apps for mobile, web, and desktop from a single codebase. It is based on the Dart programming language and uses its own rendering engine, Skia.

Flutter is admired for its speed, adaptability, and user-friendly approach. It uses a programming style that simplifies the development of intricate user interfaces. A standout feature of Flutter app development is “hot reload,” allowing instant visualization of code changes within your app.

Developers favor Flutter because it streamlines development, saving time and money. Instead of building separate apps for each platform, you can use a single codebase, leading to fewer bugs and higher app quality.

In the Stack Overflow Developer Survey 2023, Flutter was the most loved cross-platform framework, with a score of 8.6 out of 10. It was also the most wanted cross-platform framework, with a score of 8.4 out of 10.

Key Features of Flutter

The best Flutter app development company in the world leverages Flutter for their mobile app development because of the following features-

Flutter App Development offers several key features:

Cross-Platform Capability

With Flutter, you can build applications for various platforms like Android, iOS, web, desktop, and more using a single set of code. This streamlines development efforts and saves time.

Instant Code Updates

Flutter’s “hot reload” feature lets developers instantly see the effects of their code changes in the app’s user interface. It accelerates the development process and simplifies debugging.

Extensive Widget Library

Flutter provides a wide range of customizable widgets, making it easy to create intricate and visually appealing user interfaces without much hassle.

Native-Like Performance

Flutter compiles code into native machine code, ensuring that your apps perform at a level similar to those developed using native languages like Java or Swift. This is crucial for resource-intensive applications such as games and multimedia apps.

Open-Source Framework

Flutter is open-source, granting developers access to its source code for customization and benefiting from community-driven enhancements and improvements.

Advantages of Flutter

Single Codebase: Flutter allows you to build both iOS and Android applications from a single codebase. This means you don’t need separate development teams or codebases for each platform, reducing development time and costs.

Real-time Code Reflection

With Flutter’s hot reload feature, you can instantly see the impact of your code changes on the app’s UI. This speeds up development, as you can make adjustments on the fly, enhancing productivity and debugging efficiency.

Rich UI Components

Flutter offers a wide range of customizable widgets for building intuitive and visually appealing user interfaces. These widgets follow platform-specific design guidelines (Material Design for Android and Cupertino for iOS), ensuring a consistent and native look and feel on both platforms.

Better Performance

Flutter’s compiled-to-native code execution results in high-performance applications. The Skia graphics engine, used for rendering, ensures smooth animations and responsive user experiences. This performance excellence is crucial for delivering user-centric apps.

Access to Native Features

Flutter’s plugin system enables seamless access to native device features and APIs. This means you can integrate cameras, sensors, geolocation, and other platform-specific functionality into your app, providing a complete user experience.

Open Source

Flutter’s open-source nature fosters a vibrant and supportive community. Developers benefit from a wealth of online resources, forums, and third-party packages and libraries that extend Flutter’s functionality. This active community ensures long-term support and growth.


Developing with Flutter can significantly reduce costs because of its code-sharing capabilities. You save time and resources by maintaining only one codebase for multiple platforms, making it an attractive choice for businesses looking to optimize their development budgets.

These advantages collectively make the decision to hire flutter developers a compelling choice for cross-platform mobile app development, enabling developers to create high-quality, performant, and cost-effective applications.

Okay now let’s not get biased towards flutter, and explore the cons that developers witness in their app development journey.

Cons Of Flutter In Mobile App Development

Here are the disadvantages of using Flutter in mobile app development

App Size

Flutter apps tend to be larger due to the framework and engine, potentially impacting user downloads and storage.

Limited Native Libraries

Some native functionality and third-party integrations may not have readily available Flutter plugins.

Learning Curve

Developers unfamiliar with Dart may face initial challenges in adapting to the language and framework.

What is React Native?

React Native simplifies mobile app development by allowing you to use JavaScript. It transforms a virtual design into real native components for iOS and Android, so your app looks and works just like one built with Objective-C or Java.

For building your app’s user interface, React Native uses JSX, which blends JavaScript and XML-like syntax. Think of it as similar to HTML, but with added features that make it easier to work with in the React Native environment.

Flutter vs. React Native – Detailed Difference

Flutter vs. React Native – both are widely used frameworks for building cross-platform mobile applications, and while they share similarities, they also exhibit distinct characteristics.

Programming Language

  • Flutter employs the Dart programming language, known for its efficiency and conciseness. Dart offers features tailored for mobile development, such as hot reload for real-time code changes.
  • React Native relies on JavaScript, a widely adopted language in web development.

Rendering Engine

  • Flutter utilizes its proprietary Skia rendering engine, written in C++, granting it extensive control over app aesthetics and superior performance.
  • React Native connects to native Android and iOS rendering engines through a JavaScript bridge. While flexible for cross-platform use, this approach may introduce some performance overhead.

Community Support

  • React Native boasts a larger developer community, resulting in a wealth of available resources, including tutorials, plugins, and libraries.
  • Flutter’s community is rapidly growing, narrowing the resource gap over time.

App size

  • Flutter apps tend to be larger than React Native apps, because Flutter needs to include its own rendering engine.
  • However, Flutter apps can be cached more effectively, which can help to reduce the impact of their size on performance.

Learning curve

Flutter has a steeper learning curve than React Native, because it uses a new programming language. However, Flutter’s documentation is excellent, and there are many resources available to help developers learn the language.

Flutter and React Native excel in cross-platform mobile development, with the choice depending on your specific requirements and preferences. Let’s get a clear understanding of Flutter vs. React native through a quick comparison.
