About Dart: Use ffigen

From the official flutter/agent-plugins repo. When a task needs new native bindings to C, Objective-C or Swift, this skill points the agent to package:ffigen. It covers configuring the generator, running it and wiring the output in, and it steers the agent away from handwritten dart:ffi code that drifts out of sync with headers.

A small skill, but it saves agents from a common source of subtle native bugs.
