  • React Native's reliance on third-party dependencies may lead to compatibility issues and maintenance challenges as the ecosystem evolves.

4. Flutter (Dart)


Flutter is a tool made by Google to help developers create apps for different platforms, including iOS. It uses a programming language called Dart. What's unique about Flutter is that it allows developers to build apps that feel native to iOS devices, even though they're not written in the usual iOS programming languages. This means developers can make iOS apps that look and work just like ones made with Apple's tools. It's changing how developers approach iOS app development because they can now use Flutter to create immersive experiences specifically for iOS users. Check our comparison of Flutter and React Native to find the best language out of the two.


When to Use

Flutter is suitable for projects requiring cross-platform development capabilities and a consistent user experience across various platforms, including iOS, Android, web, and desktop. Its hot reload feature and customizable UI components streamline development and enable rapid prototyping. Check our cost analysis of developing a Flutter app to know more about when to use Flutter.
