What Should You Choose from Flutter vs. React Native in 2025?

Quick Go-Through: Flutter and React Native are both known as top-tier frameworks for cross-platform mobile app development. Flutter boasts robust UI capabilities and user-centric design, while React Native shines in terms of maturity and vast community. However, the optimal choice ultimately centers around your project’s specifications and expertise nearby. This blog on Flutter vs React Native will help you understand their differences and choose the ideal one for you.

With each and every passing day, thousands of apps are added to the mobile application space. Lots and lots of reports from relevant sources how the app downloads increased by 9% in 2018, smartphone users spent USD 100 billion on apps the same year, and many more similar facts.

Talking about custom app development and cross-platform apps – their market already crossed the USD 7.5 billion mark in 2018. Wait! Why are we focusing so much on the 2018 statistics?

It is because it was in 2018 that Google launched Flutter, an open-source cross-platform development framework which in no time became a stiff competitor for the other existing and popular frameworks like React Native (launched in 2015 by Facebook). At the time of writing this post, Flutter has acquired 137K at Github as compared to 102K stars claimed by React Native.

The primary difference between Flutter and React Native is its language. Flutter uses Dart as a primary programming language, developed by Google, while React Native uses JavaScript and JSX with React for developing mobile interfaces.

In fact, the most obvious way to make a choice is by comparing the two on the basis of the most relevant aspects.

The competition is indeed tough, and it can be difficult to find out the difference between React Native and Flutter app development.

This article will help you find out which is better - Flutter or React Native. That’s what you are about to read. But before we go ahead and talk about the actual comparison, you should know that there’s a huge gap between React vs React Native. And here, we are talking about React Native.

Before that, Let’s Just Look at Their Similarities: React Native vs Flutter

While talking about React Native vs Flutter, both are open-source platforms for cross-platform mobile app development and use common features like hot reload (better known as live reload among React Native Developers). What does that mean? Hot Reload allows the developers to instantly see the changes made in the code without requiring renewing the application. It allows faster coding, development, and easy bug-fixing.

Both React Native and Flutter support the concept of one codebase for multiple mobile platforms (Android and iOS), which means exactly similar apps available for the users of each of these platforms. This type of coding also reduces the amount of testing almost by half. It is because of the convenience of writing fewer tests for different mobile platforms.

Talking about Flutter vs React Native popularity, both frameworks empower many well-known apps. While Flutter development is behind the success of Google Ads app, Hamilton Broadway Musical App, and Xianyu by Alibaba, React Native has given the world the Instagram, Facebook, and Pinterest apps, among many others. Let’s start with the comparison now!

1. Ease of Learning

When developers consider these languages, they face a question - which language should I learn: Flutter or React Native?

From the developer’s point of view, React Native is easier to learn, and there’s one valid reason behind it, it uses JavaScript as a programming language. JavaScript has been around for years, and most of the developers are familiar with it. Flutter uses Dart, which is relatively newer, and many extend the learning graph. However, it doesn’t mean that Dart makes Flutter a difficult framework. Rather it is one aspect of Google’s platform which makes it shine. You would soon learn how.

2. Community Support

When pursuing cross-platform development, support from the global development community can be a boon for many developers. Considering that React Native was launched much earlier than Flutter, it can be expected to have a vast online community offering support. You can easily get solutions for the issues and difficulties while developing an app.

Having said that, Flutter, because of the rising star it is, has a continuously-growing community of developers, and it can be expected to become huge in 2020. So, the lower maturity level in terms of community support should not be that big of a reason to not choose Flutter.

3. Performance

Performance is the most crucial factor that every framework should consider. The JavaScript-based frameworks eliminate the causes for performance. However, some JavaScript frameworks for web development don’t even offer enhanced performance on mobile, while some frameworks like TezJS optimize Core Web Vitals with matchless hyperspeed even on mobile.

While talking about React Native vs Flutter performance, React Native uses JavaScript bridges or JavaScript layers to run hybrid apps for different mobile platforms. This additional layer is what Flutter app development eliminates by allowing the developers to reuse the code which already exists without the need for JavaScript bridges.

Flutter compiles to the native code, unlike React Native, which refers to the JavaScript layer again and again for compiling. It is one of the few things that make Flutter superior to not just React Native but many others cross-platform application development frameworks.

4. Widgets vs Third-party Libraries

One of the major contrasts between the two frameworks is the levels up to which they rely on third-party libraries. Google has developed Flutter to contain a number of fantastic widgets and libraries which allow the mobile application development to render identical user interfaces for both Android and iOS. React Native, on the other hand, requires the developers to repeatedly refer to the third-party libraries. Needless to say, the difference makes the development work faster for Flutter developers.

The difference also influences the way testing is done while developing apps using the two frameworks. The widget testing support in Flutter indeed makes the task easier and speedier for the Flutter developer – while the React Native developers again need to rely on third-party tools for testing.

5. Documentation Support

Considering that Flutter has the backing of Google, one can expect its documentation support to be far more comprehensive. It really is! The content that the Flutter framework offers is more informative and detailed and can be a great reference resource for cross-platform development experts. Though React Native doesn’t lack far behind in terms of documentation support, it tends to keep the content more generalized and less to-the-point. Moreover, there is a kind of disorganization in the way the React Native app development guides are offered to the developers.

6. Few Other Points

• Ease of Installation: React Native installation is possible using Node Package Manager, which makes the process faster. The Flutter users, however, must perform some extra tasks to install the development kit.

• Development Time: The time-to-market with the Flutter app development framework is less – due to the amazing support of widgets. However, you must hire dedicated developers who are experienced in Dart programming to enjoy this benefit. React Native also offers quick development, though more reliance on native elements and JavaScript bridges may add to the overall time.

• CI/CD Support: Flutter boasts of a command-line interface (CLI) that allows setting up continuous integration (CI) and continuous delivery (CD) easily and with fewer efforts. This is where Reach Native lacks behind as it offers no guidance on setting up CI and CD services. Flutter’s command-line interface also allows automated app deployment, making it easier to release apps on the specific app stores of different mobile platforms. It is an important requirement in the case of cross-platform development, and Flutter fulfills it aptly.

What Should Be Your Choice: Flutter or React Native?

In recent times, cross-platform apps have witnessed much more acceptance. You really need to be competitive in developing a quality app. Now, the question is which among the two frameworks, Flutter and React Native framework, would match your needs and desired results. For this, let’s compare them once again on the basis of the benefits that cross-platform apps offer.

Code Reusability: With the support of widgets, code reusability is much more efficient and result-oriented in the case of Flutter app development.

UI Consistency: Flutter is more acceptable for rendering identical UI designs for the two popular mobile platforms – iOS and Android.

Shorter Time-to-Market: As mentioned earlier, Flutter promises a shorter development time and thus is better than React Native in this regard.

Cost-Effectiveness: The development cost may be the same using any of these frameworks. However, it would depend on how experienced the development team is.

Extended Reach: Cross-platform apps always reach a wider audience as compared to native apps. Again, it would depend on the out-of-box app design you offer.

Choose Flutter, if your app requirements fall into the given criteria:

• If your app doesn’t need any native functionality.
• If you are running out of budget and have a short timeframe to complete a project.

The Future of Flutter and React Native

In the year 2022, many organizations are adapting Flutter app development for their project requirements. After all, we have seen many improvements, new features, and functionalities in the Flutter SDK as Google evolves and redefines its tool. For instance, its hot reload feature allows you to iterate and experiment much faster, leading to a more efficient development process

Furthermore, recently, with the new release of Flutter 2.10, it has extended its stable support for Windows applications. Flutter for Windows has not just opened doors but windows of every organization. Hence, the popularity of flutter desktop app development is rising quickly.

In a nutshell, many big brands like Alibaba are already using Flutter. Therefore, we can conclude that the future of Flutter looks very promising for the toolkit.

While talking about React Native platform, it is also used by the giant Facebook on a large-scale re-architecture of the technology.

Flutter offers many features like:

• Enhanced memory footprint and Dart Virtual Machine
• Improved tracing feature
• Better ecosystem
