Unlocking Native Power: Deep Dive into Dart Build Hooks
summary
Dart Build Hooks (preview now, planned stable in the next release 3.10) provide a JSON protocol to inject build logic via a package-local hook/build.dart that compiles native code, produces code assets (dynamic libraries) and writes an output JSON consumed by Dart/Flutter. Demo builds SQLite from a single C source using package native_toolchain_c’s C builder which invokes clang, produces a namespaced asset used by FFI-generated bindings, passes dart test, supports multi-arch caching in a shared output dir and is asset-type agnostic with extension APIs for custom asset types.
