Dart FFI Binding Generator

What it does

This skill provides a standardized, automated workflow for generating Foreign Function Interface (FFI) bindings in Dart using the package:ffigen tool. It eliminates the need for manual DynamicLibrary.lookup calls and hand-written struct classes, which are typically brittle and error-prone.

When to use it

Activate this skill when the task involves:

• Creating new FFI bindings for C, Objective-C, or Swift libraries.
• Extending existing native integrations.
• Refactoring hand-crafted dart:ffi setups into a maintainable, generator-based system.

What's included

• Instructions: A detailed step-by-step guide covering dependency management, dynamic path formulation, generator script creation (tool/ffigen.dart), and static analysis verification.
• Best Practices: Strict constraints on header locations, inclusion filters to minimize binary size, and mandatory license preamble requirements.
• Verification: A comprehensive checklist including dart analyze and specific handling for compiler errors versus lint warnings.
