Key Comparison Factors
Now to make things easier, below are the key factors for you to check with before making any decision.
- Performance
- Because of its Ahead-of-Time (AOT) compilation, Flutter provides almost native performance.
- Complex applications may run more slowly since React Native relies on the JavaScript bridge.
- Since it compiles straight into platform-specific code, Kotlin offers native performance.
2. Development Speed
- Flutter’s hot reload function accelerates UI testing and iterations.
- Its well-known JavaScript syntax lets React Native enable fast prototyping.
- Although it may take longer, Kotlin’s native approach guarantees strong outcomes.
3. Community & Support
- Among the three frameworks, React Native boasts the biggest community.
- With significant Google backing, Flutter’s community is expanding quickly.
- Its inclusion with Android Studio means Kotlin has a smaller yet passionate community.
Choosing the Right Framework
Now when you have complete clarity about the frameworks, it is important that you understand the attributes that can help you choose one. So, below we will give you some of the essential options to consider.
Option 1: If the priority is a visually stunning application, make sure to hire Android app developers who have the expertise of working in Flutter platform.
Option 2: Now if you are getting the application with timeline as concern, then you must go for Javascript developers with react native know-how.
