SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ffigen.

What problem does it solve?

This skill eliminates the manual, error-prone process of writing Dart FFI bindings by automating the generation of type-safe code directly from native C/C++ header files.

Core Features & Use Cases

  • Automated Binding Generation: Uses package:ffigen to parse native headers and generate Dart FFI code, ensuring ABI compatibility and structural accuracy.
  • Tree-Shaking Support: Configures recorded usage mapping to enable native asset tree-shaking, reducing binary size in production builds.
  • Use Case: When integrating a C library like SQLite or a custom native module, use this skill to generate the necessary Dart glue code instead of manually defining pointers and function types.

Quick Start

Use the dart-use-ffigen skill to generate FFI bindings for the native header files located in the third_party directory of this project.

Frequently Asked Questions about dart-use-ffigen

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate Dart FFI bindings from C header files?▼

To generate Dart FFI bindings from C header files, use the ffigen package to parse native headers and automatically produce type-safe Dart glue code. This automation ensures structural accuracy and ABI compatibility without manual pointer definitions.

What is the best way to automate native library integration in Flutter?▼

Automating native library integration in Flutter is best achieved by generating FFI bindings directly from C/C++ headers. This approach eliminates error-prone manual code writing and ensures type safety when connecting Dart to native modules.

How do I configure ffigen to reduce binary size in production builds?▼

To reduce binary size in production builds using ffigen, configure recorded usage mapping to enable native asset tree-shaking. This process strips unused native code, optimizing the final application package.

Does ffigen require specific configuration for entry points and output paths?▼

Yes, ffigen requires proper configuration of entry points, inclusion filters, and output paths to ensure generated Dart FFI bindings maintain type safety and tree-shaking compatibility.

Why use automated FFI code generation instead of manually defining Dart function types?▼

Automated FFI code generation is preferred over manually defining Dart function types to eliminate human error and ensure ABI compatibility. It parses C/C++ headers directly to structurally accurately map native libraries.
