Vendored Skia Dart Modifications

This file records local changes made under third_party/skia_dart so we can track the delta from the published package and avoid losing rendering-critical API work during future vendor refreshes.

That sounds like an ambitious and exciting project! I'll research how to upgrade the SkWasm renderer to use Skia Graphite and adapt it to run natively on iOS. This will involve understanding the SkWasm renderer, Skia Graphite integration, and modifying the Flutter engine for iOS compatibility. I'll get back to you with a detailed breakdown and potential implementation steps.

Upgrading Flutter’s SkWasm Renderer to Skia Graphite (with iOS Native Integration)

Introduction

Flutter’s SkWasm renderer is a new WebAssembly-based rendering backend that uses Skia for Flutter Web apps. It aims to reduce download size and enable multi-threaded rendering on the web (Web renderers | Flutter). Meanwhile, Skia Graphite is an upcoming Skia rendering architecture designed for modern graphics APIs (Metal, Vulkan, WebGPU) to replace Skia’s traditional GPU backend (Ganesh) ([Switch from Ganesh to G
