SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires code_assets, hooks, native_toolchain_c, record_use, ffigen.

What problem does it solve?

This skill removes the complexity of manually configuring native C/C++ interop in Dart and Flutter projects by automating the compilation, linking, and packaging of native code assets.

Core Features & Use Cases

  • Native Asset Hooks: Automates the build and link lifecycle using Dart's native hooks system.
  • Tree-Shaking Optimization: Reduces binary size by stripping unused native symbols during the linking phase.
  • Use Case: When integrating a C-based library like SQLite, use this skill to handle cross-platform compilation, verify binary integrity via cryptographic hashes, and ensure the final application bundle only contains necessary native symbols.

Quick Start

Use the dart-setup-ffi-assets skill to configure the build and link hooks for the native C library in this project.

FAQPage Schema
How do I automate C/C++ native asset compilation for Dart and Flutter projects?

Automating C/C++ native asset compilation uses Dart's native hooks system to orchestrate the cross-platform build and link lifecycle. This compiles C/C++ source code into native code assets, removing manual interop configuration complexity.

What is native asset tree-shaking and how does it reduce Flutter binary size?

Native asset tree-shaking reduces Flutter binary size by stripping unused native symbols during the linking phase. This ensures the final application bundle only contains necessary native symbols, optimizing high-performance native interop distribution.

How do I configure Dart build and link hooks for C libraries like SQLite?

Configuring Dart build and link hooks for C libraries like SQLite requires setting up programmatic build toolchain orchestration. This handles cross-platform compilation, verifies binary integrity via cryptographic hashes, and packages native code assets.

Does Flutter native asset integration support binary integrity verification?

Yes, Flutter native asset integration supports secure binary integrity verification via cryptographic hashes. This ensures compiled C/C++ source code packaged into native code assets remains secure and unaltered during cross-platform distribution.

What is the best way to package C interop code for cross-platform Flutter distribution?

The best way to package C interop code for cross-platform Flutter distribution is using native asset hooks to automate compilation and linking. This approach optimizes linker tree-shaking and strips unused native symbols for reduced binary size.
