FAQs – Flutter vs React Native

  • Is Flutter better than React Native?

    Well, this is true up to a great extent. Flutter is very easy to use, and it remains more resistant to frequent updates. It means that when Android or iOS operating systems get any updates, the application remains the same. On the other hand, React Native relies heavily on native elements, so whenever the operating system gets any update, your application may encounter some sort of problems.

  • Is Flutter used for User Interface (UI) only?

    Flutter is a frontend SDK, which is also known as UI plus business logic. People often misunderstood that Dart is used for the backend, but on contrary, Dart is used for frontend logic only, hence we can say that Flutter is purely a frontend SDK.

  • Which has more job prospects React Native or Flutter?

    React Native uses one of the most popular development languages, that is JavaScript. React Native enjoys the support of the JavaScript community, which gives it a sizeable advantage over Flutter when it comes to job prospects.

  • How React Native code is compiled?

    As we know, React Native utilizes JavaScript to compile the user interface of an application, but it also uses native-OS views. To incorporate additional features, React Native allows code compilation in OS-native languages (Kotlin and Java for Android and Objective-C and Swift for iOS).

  • What cannot be accomplished using Flutter?

    Flutter can’t be used to develop an application for WatchOS, tvOS, Android Auto, or CarPlay. Flutter offers very limited support for Wear OS, which was formerly known as Android Wear. You must integrate Bit code support for Flutter to deploy to WatchOS and tvOS. It is necessary to use an alternative framework or native code to develop applications on these platforms.
