nitro_generator 0.2.0

Code generator for Nitro Modules (Nitrogen). Converts *.native.dart specs to Dart FFI, Kotlin, Swift, and C++ bindings.

nitro_generator

A high-performance code generator for Nitro Modules (Nitrogen). This package converts your Dart interface specifications into optimized native bindings for Android (Kotlin/JNI), iOS (Swift), and C++.

Features

• Performance-First: Generates lean, zero-copy FFI bindings.
• Cross-Platform: Unified generation for Dart, Kotlin, Swift, and C++.
• Type-Safe: Maps Dart types to their native counterparts with strict validation.
• Complex Types: Supports @HybridObject, @HybridStruct, and @HybridEnum.
• Async Support: seamless @nitroAsync bridging for non-blocking native calls.
• Streaming: Robust @NitroStream support with configurable backpressure strategies.
• Binary Records: High-performance @HybridRecord support using a compact binary protocol, eliminating JSON serialization overhead.

Usage

1. Define your native module interface in a .native.dart file.
2. Annotate your classes with @HybridObject, structs with @HybridStruct, etc.
3. Run the generator:

flutter pub run build_runner build

The generator will produce:

• lib/src/generated/*.g.dart: Dart FFI bindings.
• android/src/main/kotlin/.../*.bridge.g.kt: Kotlin JNI bridge.
• ios/Classes/*.bridge.g.swift: Swift bridge.
• ios/Classes/*.bridge.g.mm: Objective-C++ bridge (for exception safety).
• src/*.bridge.g.h: C++ headers.
