Cross-platform mobile development is gaining momentum due to its ability to reduce development time and cost by using a single codebase for Android and iOS. While frameworks like React Native have set the foundation, newer alternatives like Flutter and Lynx have redefined performance and developer ergonomics.
Why Flutter Has Good Performance
🔧 1. Native Compilation (AOT)
Unlike some other cross-platform frameworks, such as React Native, which rely on JavaScript interpreters and runtime bridges to communicate with native components, Flutter adopts a different and more optimized approach. When a Flutter app is built in release mode, the Dart codebase is compiled ahead of time into native machine code. This means that all the Dart code is converted directly into the machine-level instructions required by the target platform — be it Android or iOS — before the app is installed or run.
This AOT compilation provides a major performance boost. Since the app is already in the language the device understands, there is no need for an interpreter at runtime, and the application can start executing instantly. This significantly reduces startup time, ensures faster runtime execution, and improves…
There is a new rendering engine called Impeller in Flutter which is now used by default on both Android and iOS which gives much better performance. Skia is not the default renderer for flutter now in mobile platforms. Please update this.
