Below, we compare these two technologies across several performance metrics.

Performance Metrics

• Compilation and Execution: Flutter compiles to native ARM code, leading to faster execution and smoother animations. React Native, however, uses JavaScript, which is interpreted at runtime, leading to slightly slower performance in comparison.
• UI Rendering: Flutter uses a custom rendering engine (Skia), which enables it to have full control over UI rendering, while React Native uses native components and bridges JavaScript with native code, which can cause some delays in rendering, especially with more dynamic UI elements.
• Memory Usage: Flutter generally uses more memory because of its custom rendering engine. React Native, though it uses native components, can be more efficient with memory usage in some cases due to the use of native code.

“Flutter’s direct compilation to machine code allows it to outperform React Native in many cases, especially in high-performance applications like games and graphics-heavy apps.”

Key Differences in Performance

Metric	Flutter	React Native
Compilation	Compiled to native code (ARM)	Interpreted through JavaScript bridge
Rendering Engine	Custom Skia engine	Uses native components via bridge
Performance in Complex Apps	Superior due to direct native compilation	May experience delays due to JavaScript bridge
Memory Usage	Higher due to custom rendering engine	More efficient in certain cases with native components

Conclusion

While both frameworks offer great cross-platform capabilities, Flutter tends to outperform React Native in terms of raw performance due to its native compilation and custom rendering engine. React Native, however, remains a solid choice for developers looking for a quicker development cycle and easier integration with native code.
