    Flutter Vs React Native : Performance Benchmarks you can’t miss ! 🔥⚡️

    When choosing between Flutter and React Native for mobile app development, performance is a crucial factor. A recent benchmarking study compared app size, memory, and CPU usage for three app types on both frameworks using current versions. Flutter generally showed smaller APK sizes and better CPU & memory usage, with smoother scrolling and fewer framedrops compared to React Native. However, React Native had a higher FPS in bulk Lottie animations but at the cost of increased CPU and memory usage. The findings suggest that while both have their strengths, Flutter slightly edges out in overall performance efficiency.

    Rust GUI library via Flutter, done simple

    Combining Rust's powerful programming capabilities with Flutter's popular and mature cross-platform development features enables efficient GUI creation. Using the flutter_rust_bridge, developers can seamlessly integrate Rust's state and logic with Flutter's flexible and responsive UI elements. This approach leverages Flutter’s extensive ecosystem and hot-reload feature for rapid UI development, while also acknowledging certain compromises such as the necessity for boilerplate code and the split between Rust logic and Flutter UI.

    Dio + JWT in Flutter — Solution of async hell

    JWTs, or JSON Web Tokens, are used for authorization in backend services by providing access and refresh tokens. In Flutter, handling async HTTP requests can lead to multiple token refresh attempts when access tokens expire. To manage this, Dio's QueuedInterceptor can queue requests and handle tokens more efficiently. Key functionalities include a token validator, request refresher, and a request retry mechanism to ensure smooth operation and security.
