Benchmarking rendering performance, memory footprint, startup time, and third-party library ecosystems.
Choosing between Flutter and React Native is a critical architectural decision for modern cross-platform mobile initiatives.
### Rendering Architecture Comparison
- **Flutter**: Employs the Impeller C++ rendering engine, drawing directly onto the GPU canvas. This guarantees consistent 60fps/120fps animations without bridge bottlenecks.
- **React Native**: Leverages the New Architecture with Fabric renderer and TurboModules, providing native UI component fidelity and seamless interoperability with native iOS/Android libraries.
### Decision Matrix
- Select **Flutter** when custom UI components, pixel-perfect multi-platform parity, and graphic-intensive experiences are top priorities.
- Select **React Native** when extensive code sharing with an existing React web codebase and native OS UI controls are paramount.
