Flutter vs. React Native: Comparing 5 Essential Factors

01 | Performance

Choosing the right framework often boils down to performance. Let’s analyze how well each framework handles animations, complex designs, and speed.

Aspect	Flutter	React Native
Compilation	Directly compiles into native ARM code, ensuring consistent performance across platforms. Ideal for complex UIs and animations.	Relies on a JavaScript bridge to communicate with native modules. Hermes (a JavaScript engine) has improved this, but slight delays may occur in complex apps.
Rendering	Uses Skia, a custom rendering engine, bypassing reliance on native components.	Depends on native components for rendering, which can introduce inconsistencies across platforms.
Animations	Delivers smoother animations due to its self-contained rendering pipeline.	Animations are decent but can lag in highly intricate scenarios.
Complex UIs	Excels in maintaining performance for intricate and dynamic UI designs.	Performance can vary depending on native module integration.
Speed	Direct compilation makes Flutter generally faster for rendering-intensive tasks.	Optimized for most use cases, but may lag behind Flutter in high-performance demands.

The choice between Flutter and React Native ultimately depends on the specific performance needs of your project. Complex UI? Hire a Flutter developer. A simpler app with native-like interactions? Hire a React Native developer instead.
