React Native vs. Flutter : A performance comparison between cross-platform mobile application development frameworks

Abstract: This study compares the performance of two popular cross-platform mobile application development frameworks, Flutter and React Native. As the number of mobile users continues to grow, the ability to target multiple platforms using a single codebase is increasingly important for developers and companies. We conducted three manual UI tests; scrolling through a list, testing the camera, and filtering a large dataset to measure the performance of the frameworks in terms of CPU usage, memory usage, and janky frames on an Android device. The results indicate that Flutter may provide better performance in specific situations when compared to React Native. The study contributes to the existing research by providing additional insights into the performance of these frameworks under specific test scenarios.
