Flutter Vs React Native – Detailed Framework Comparison

Native applications tend to work smoothly across mobile devices. The graphic transitions of these applications take less time for User Interface (UI) rendering in comparison to cross-platform applications. The reason for this is simple –the code is capable of communicating straight to the mobile Operating System (OS) core, supporting UI methods.

On the other hand, native mobile Operating Systems are composed of different languages. For instance, the Android Operating System serves to be a mix of C++ and C. On the other hand, the iOS platform is built on the concepts of Swift and Objective C. Therefore, native mobile app development requires knowledge of some basic programming languages like Java and Swift.

Cross-platform mobile applications tend to be less competitive when it comes to graphic animation. To top it all, they are highly cost-efficient and a great fit for early-stage startups or firms. To support the concept, Facebook came up with React Native in 2015. The concept of cross-platform mobile app development became true. You are only expected to code once. The next major advancement took place in 2017 when Google unveiled Flutter. It is based on the Dart programming language.

react native app development

React Native has been effectively implemented by thousands of businesses across the world –including Facebook, Instagram, Microsoft, and so more, across a wide range of industry verticals. React Native or RN is a leading JavaScript-based mobile application framework that ensures the development of natively-designed applications for Android and iOS. The framework allows developers to create an application for different platforms with the help of a single codebase. Hire React Native developers from reliable agencies.

React Native was first unleashed by Facebook as an open-source technology in 2015. In just a few years, it managed to become one of the highly sought-after solutions for mobile app development. In the modern era, React Native is used for powering some of the most famous apps in the world –including Skype, Facebook, Instagram, and so more.

Before React Native, ReactJS was released as in the competition of React Native Vs. ReactJS. Initially, ReactJS was given the status of serving as an open-source technology by Facebook. With time, the development of React Native took place. ReactJS tends to focus on mobile-first design. On the other hand, React Native is utilized for native mobile application development.

Pros & Cons of React Native

Pros Of React Native

There are several benefits of using React Native for mobile app development. These are:

#Great Community Support

As it is an open-source network, React Native from a reliable React Native app development company allows its community of developers to go through all possible documentation with respect to the technology free of cost. Moreover, the platform also allows developers to deliver their contributions whenever they want to.

React Native is a platform that is entirely community-driven. Therefore, you can always look forward to reaching out for guidance from other experienced developers, browsing relevant information, and helping other developers as well. Developers can leverage the benefit of the active community by asking others to offer relevant feedback or review ongoing projects.

#Optimal Performance

The effectiveness of React Native is due to its use of controls and modules for improving overall performance. The platform operates by interacting with the native components of iOS and Android. It then proceeds to generate codes to the native APIs that remain independent of any type of interference.

Performance improvement is the direct result of the given framework as it makes use of a distinct thread –separating it from the UIs and native APIs.

#Pre-Developed Components And Code Reusability

One of the most crucial benefits of using React Native for app development is the ease of code reusability. All that the developers are expected to do is make use of around 90 percent of React Native codes for Android and iOS. This significantly helps in reducing the overall time as well as the cost of the app development project.

The presence of pre-developed components in the respective open-source library of the platform allows developers to access necessary codes freely. The given codes are already composed. The developers only have to get them ready for deployment. This results in faster development of the application.

#Simplified UI

The driving force behind the functionality of React Native is its uncomplicated and simplified mobile UI or User Interface. The JavaScript library in the platform is like the open-source framework instead of serving as the traditional framework. As such, developers are capable of achieving the right sequence for the development of apps. In most cases, the applications that are designed using React Native tend to be highly responsive, take less time to load, and feature seamless UX.

Cons Of React Native

Some of the disadvantages of React Native are:


React Native serves as a relatively newer entrant into the application development industry. The methods associated with the React Native lifecycle have not totally assessed as yet. This is the reason why it might have an unpredictable or negative impact on the functions of the app. The React Native framework keeps evolving every now & then –featuring newer updates almost every week. Therefore, app developers need to be updated on a regular basis to be aware of such changes.

#Difficulty In Learning

It can be a complicated process to learn React Native –especially for beginners in the field of app development. Additionally, along with the React Native framework, developers are expected to have knowledge about native app coding. React Native libraries having native bridges for features like maps, videos, and so more will require in-depth knowledge of the developers.

#Reduced Security

React Native serves as a JavaScript library. Moreover, it is also an open-source framework. Due to this, developers might face the challenge of ensuring that the app remains safe and secure at all times. JavaScript is quite sensitive. Therefore, developers might experience reduced levels of security in some cases.

The presence of pre-developed components in the respective open-source library of the platform allows developers to access necessary codes freely. The given codes are already composed. The developers only have to get them ready for deployment. This results in faster development of the application.

The creation of an open environment for discussing React Native is another major step in that direction. It serves to be a sign of ensuring an ongoing environment. Moreover, it also signals the bright future of the framework. As React Native has a stable position in the app development marketplace, it is on the path of continuous development.

Under all circumstances, Flutter continues to be a strong competitor to React Native.

React Native Or Flutter –Insights From App Owners And Developers

Jitendra Jain, Co-founder at Inventcolabs – “The major benefit of Flutter app development over React Native is the absence of platform restrictions. Flutter has no limitations from the platform UI. This is because it does not make use of the same. It continues rendering everything by itself. This tends to set the developers free when it comes to building the best User Experiences (UX) without making any compromises. It tends to be a major difference between Flutter and React Native.”

Sandeep Agrawal, Chief Engineer at Inventcolabs – “React Native serves to be the closest competitor to Flutter. I like React Native as it helps in setting the standard for ensuring cross-platform app development. However, during my experience with React Native, our team came up with some issues. These:

React Native simply replicates conventional and native methods. Therefore, it requires a proper bridge for translating the respective calls into the native API. This could be a challenging aspect when there are several native calls taking place. You can come across solutions for the same. However, with Flutter, there is no need to worry about the given issue. This is because the view layer gets rendered just like a game. Moreover, all components are designed by engineers and specialists of Flutter. As such, there are minimal native calls for bridging.

It is not always possible to customize the components of React Native. They are simply wrappers around the original native view. Therefore, if someone has made the decision not to wrap a particular method, then there is no requirement to access it. At the same time, new components by Apple and Google can no longer be available on React Native.

It takes longer to fix bugs on React Native. For instance, the dashed border issue along with separate issues supporting builds flavors and so more. Most companies that run React Native in production, execute a custom fork to fix errors that are not fixed upstream. The Flutter development tends to be more proactive. Moreover, you can expect fixes quickly. We end up spending most of the time searching for issues in the documentation of React Native. Then, it is expected to figure out why things were not working the way they should.

Hire flutter developers


Flutter or React Native –which one to choose? It might not have a clear winner. This is because project requirements tend to vary significantly. Therefore, the selection of the right framework will entirely depend on the specific business requirements and project parameters. Nevertheless, both React Native and Flutter are great frameworks for helping you develop a cross-platform application easier and faster when compared with other tools.
