Building a High‑Performance Genshin Impact Map with CanvasKit, Gesture Recognition, and React/Vue Integration

This article explains why the official web map built with Leaflet suffers from poor performance, how using CanvasKit (Skia compiled to WebAssembly) together with @use-gesture and popmotion dramatically improves rendering speed and interaction smoothness, and provides a complete implementation and component wrappers for Vue and React.

Flutter Event Propagation and Gesture Recognition Mechanism (Source Code Analysis)

Flutter converts native MotionEvent data into a serialized ByteBuffer, passes it through JNI to the engine, creates a Dart PointerDataPacket, hit‑tests the render tree, dispatches the event to each hit object, and resolves competing GestureRecognizers in the arena so the winning recognizer triggers the appropriate callback such as onTap or onDrag.
