Flutter and React Native are two of the best options for cross-platform mobile development, and they both have advantages and disadvantages over one another.
React Native pros:
Use on a global scale: React Native has been around for quite some time. It has a large user base and approximately 42 % of app developers.
Installation: The React Native framework is simple to install. All you need is a solid understanding of Java.
React Native Cons:
Documentation and release. For release and documentation, React Native adheres to standard manual procedures. As a result, the process is quite slow.
Language for programming: Dart is a programming language designed specifically for Flutter. Dart is a new favorite among developers because it is both fast and elegant.
Documentation and release: The flutter platform is designed in such a way that applications developed with it can be quickly and easily released into online application stores such as the Google Play store. The platform is also designed in such a way that documentation of new application programs can be completed quickly and easily.
Installation: Installing flutter is typically a slow and laborious process. This is due to the fact that you will first require the binary for either GitHub or macOS.
Language for programming. Dart, the programming language used for flutter, is a relatively new language. The majority of developers are unaware of how it works. This makes it difficult to find developers who can use flutter professionally.
Use on a global scale: Flutter is only now gaining traction in the mobile app development market. Other platforms, such as react-native, have gained traction and popularity.
To recapitulate, both flutter and React Native are good, if not the best, in their respective fields. It is entirely up to the client and the work at hand to determine which works best for them.
